Stair climbing

Stair climbing is the physical activity of ascending flights of stairs, serving as a simple, accessible, and low-impact form of aerobic exercise that engages multiple muscle groups while minimizing joint stress compared to high-impact alternatives like running.^[1]^[2]^[3] As an everyday practice, stair climbing offers significant health benefits, including improved cardiorespiratory fitness, enhanced body composition, reduced blood pressure, better cholesterol profiles, and increased insulin sensitivity, which collectively lower the risk of cardiovascular disease and metabolic disorders.^[4] Regular participation, such as climbing more than five flights daily, has been associated with approximately a 20% lower risk of cardiovascular disease and a 39% lower likelihood of dying from cardiovascular disease, independent of other lifestyle factors.^[5]^[6]^[7] It also strengthens bones, muscles, and joints, aids in weight management by burning calories efficiently—up to 10 times more than sitting—and boosts mood and cognitive performance through short bouts of vigorous activity.^[8]^[9] These advantages make it particularly suitable for beginners, older adults, and those in cardiac rehabilitation, as it can be integrated into daily routines without specialized equipment.^[10] In its competitive form, known as tower running, stair climbing has developed into an organized sport where athletes race up the stairwells of skyscrapers and landmarks, testing endurance, speed, and mental resilience over thousands of steps.^[11] The sport's origins trace back to November 26, 1905, when the first recorded event, the "Stair Championship," was held at the Eiffel Tower in Paris, organized by the newspaper Les Sports; cyclist Eugène Forestier won by climbing 729 steps to the second level in 3 minutes and 12 seconds.^[12]^[13] Tower running gained momentum in Europe during the late 20th century and spread globally, with over 300 events held annually worldwide by the 2020s, including major races like the Empire State Building Run-Up in New York and the Towerrunning World Cup series. As of 2025, events continue to grow, with races like the Empire State Building Run-Up attracting international participants.^[11]^[14]^[15] These competitions, often spanning 200 to 600 vertical meters, attract elite athletes and recreational participants, fostering international federations like the Towerrunning Association and highlighting urban architecture as a venue for physical challenge.^[11]

Overview and History

Definition and Everyday Importance

Stair climbing refers to the physical act of ascending or descending a series of steps using the legs, commonly encountered in residential homes, office buildings, and public structures such as outdoor staircases in parks or urban environments.^[4] This activity is distinct from the use of mechanical aids like escalators or elevators, as it relies solely on human propulsion to navigate vertical changes in level.^[17] As a fundamental form of locomotion, stair climbing integrates seamlessly into routine navigation of multi-level spaces, making it a ubiquitous element of daily mobility for most people.^[18] In everyday life, stair climbing serves as an incidental form of physical activity, often promoted through public health initiatives that encourage individuals to opt for stairs over elevators to accumulate movement without dedicated exercise time.^[19] Campaigns such as "Take the Stairs," supported by organizations like the Centers for Disease Control and Prevention (CDC), utilize signage, motivational prompts, and workplace programs to foster this habit in settings like offices and public facilities, highlighting its role in enhancing overall activity levels.^[19] These efforts emphasize stair climbing's convenience, as it requires no special equipment, gym membership, or travel, allowing integration into commutes, errands, and household tasks.^[20] The low-impact nature of stair climbing makes it particularly accessible for beginners, older adults, and those seeking alternatives to high-impact exercises like running, as it minimizes joint stress while engaging major muscle groups.^[20] For instance, it supports gradual fitness progression without overwhelming novices, and its moderate intensity suits individuals with mobility limitations or those recovering from inactivity.^[17] In research contexts, stair climbing is employed in gait and biomechanics studies, where specialized tools like force plate-mounted stairs measure ground reaction forces, joint kinetics, and movement patterns during ascent and descent to analyze human locomotion.^[21] Such instrumented setups, often used in laboratory settings, provide precise data on lower-limb mechanics, aiding investigations into balance, coordination, and fall prevention.^[22] Since the 1960s, stair climbing has been featured in health promotion efforts within popular culture, coinciding with the broader rise of aerobic exercise advocacy that positioned everyday activities as viable paths to fitness without the need for structured routines or facilities.^[23] Public health messaging during this era, influenced by early epidemiological studies linking physical activity to longevity, began exhorting people to incorporate stair use as a simple, equipment-free strategy for maintaining vitality amid increasingly sedentary lifestyles.^[23] This cultural shift underscored stair climbing's practicality, transforming it from mere necessity into a recommended habit for incidental health maintenance.

Historical Development

Stairs have been integral to architecture since ancient civilizations, serving as practical means of vertical movement rather than deliberate exercise. In ancient Egypt, the Step Pyramid of Djoser at Saqqara, constructed around 2670 BCE, featured external stepped structures that required climbing, symbolizing ascent to the divine, while internal passages in later pyramids facilitated laborious ascents for construction and rituals.^[24] Similarly, Roman engineering incorporated extensive stair systems in monumental structures like the Colosseum (completed 80 CE), where tiered seating demanded frequent ascents for spectators and workers, though these were utilitarian rather than fitness-oriented.^[25] Stair climbing as a purposeful form of physical exercise only emerged in the 20th century, amid growing awareness of cardiovascular health in industrialized societies. A pivotal milestone occurred in 1968 with the publication of Dr. Kenneth H. Cooper's book Aerobics, which popularized aerobic activities to enhance heart and lung function, explicitly including stair climbing as an accessible, high-impact option for building endurance without specialized equipment.^[26] Cooper's point system for exercise intensity, developed from his work with astronauts, assigned values to activities like stair ascent, positioning it as a benchmark for aerobic fitness and influencing public health recommendations.^[27] This shift aligned with the broader fitness movement of the era, transforming everyday actions into structured workouts. The 1970s and 1980s saw stair climbing integrate into gym culture through technological innovation. In 1983, Lanny Potts, Jim Walker, and George Schupp invented the StairMaster, a revolving staircase machine inspired by the endurance demands on oil rig workers who climbed multiple flights daily to maintain fitness in remote locations.^[28] Marketed by their company Tri-Tech, the device gained traction during the U.S. aerobics boom, appearing in fitness centers and celebrity-endorsed videos, and making stair climbing a staple of indoor exercise routines.^[29] The first recorded competitive stair climbing event occurred in 1905 at the Eiffel Tower, though modern organized competitions gained prominence starting with the 1978 Empire State Building Run-Up, organized by the New York Road Runners Club, where participants raced up 1,576 steps to the 86th floor.^[30] This event, won by firefighter Gary Muhrcke in 12 minutes and 33 seconds, highlighted the physical challenges of urban high-rises and inspired similar races worldwide.^[31] In the 21st century, stair climbing evolved into the global sport of tower running, with post-2000 proliferation of events in skyscrapers like Taipei 101 and the Willis Tower, coordinated by the Towerrunning World Association founded in 2013 to standardize rankings and championships.^[32] Simultaneously, it became a core element of firefighter training programs, emphasizing practical endurance for high-rise responses, as seen in simulations replicating the demands of carrying gear up dozens of flights during emergencies.^[33]

Physiological Aspects

Energy Expenditure

Stair climbing imposes varying metabolic demands depending on direction, with ascending primarily involving concentric muscle contractions to elevate the body's center of mass against gravity. The fundamental physical requirement for ascent is to overcome gravitational potential energy, expressed by the equation E = m g h, where m is the individual's body mass in kilograms, g is the acceleration due to gravity (9.81 m/s²), and h is the vertical height in meters.^[34] Human gross mechanical efficiency during this activity averages around 24%, meaning the metabolic energy expended exceeds the potential energy gain by a factor of approximately four due to inefficiencies in muscle work and heat production.^[34] For a 70 kg person ascending a standard 15 cm step, the potential energy change is $70 \times 9.81 \times 0.15 \approx 103 J, equivalent to about 0.025 kcal (using 1 kcal = 4184 J), but empirical measurements show a metabolic cost of roughly 0.11 kcal per step.^[35] Descending, by contrast, relies on eccentric muscle contractions to brake the body's motion, resulting in substantially lower energy demands—typically about half those of ascending the same height—while still exceeding resting metabolism.^[35] In comparison to level walking, which averages 3-4 METs (metabolic equivalents, where 1 MET ≈ 3.5 mL O₂/kg/min or 1 kcal/kg/h), stair ascent requires approximately 2-3 times more energy, reaching 8-10 METs, whereas descent demands about 1-1.5 times that of walking.^[35]^[36] For example, ascending 10 short flights totaling 3 m of vertical height sustains an intensity of 8-10 METs over the duration (a standard flight is approximately 12 steps or 3 meters vertical).^[36] A seminal study by Teh and Aziz (2002) measured these costs via direct oxygen uptake during climbs of an 11-story staircase (27 m height, 180 steps of 15 cm each), reporting gross energy expenditures of 19.7 kcal for ascent (9.6 METs, 10.2 kcal/min) and 9.0 kcal for descent (4.9 METs, 5.2 kcal/min) in healthy adults, with costs scaling linearly at 0.11 kcal/step ascending and 0.05 kcal/step descending for a 70 kg individual (~0.0016 kcal/kg/step).^[35] Variations occur with speed (faster ascent elevates rate by 10-20%), added load (e.g., 5-30 kg backpacks increase costs proportionally), and incline (steeper steps or ramps raise demands per unit height).^[37]^[34] Key influencing factors include body weight, which directly scales expenditure (e.g., 0.175 kcal/step for 105 kg vs. 0.11 kcal/step for 70 kg), pace, and handrail use; overweight individuals experience higher absolute costs due to greater mass, while gripping handrails reduces oxygen uptake and energy demands by 10-20% through offloading lower-body effort.^[36]^[38]^[39]

Health Benefits and Potential Risks

Regular stair climbing offers significant cardiovascular benefits, including improvements in cardiorespiratory fitness as measured by VO2 max, which can increase by 2–5 ml/kg/min after consistent practice over several weeks.^[4] A 2023 prospective cohort study using UK Biobank data from over 458,000 adults found that climbing more than five flights of stairs daily—approximately 50 steps—was associated with a 20% lower risk of atherosclerotic cardiovascular disease, independent of genetic susceptibility to the condition.^[40] Additionally, stair climbing has been shown to lower systolic and diastolic blood pressure by up to 4.8 mmHg and improve cholesterol profiles by reducing low-density lipoprotein cholesterol and total cholesterol levels.^[4] From a musculoskeletal perspective, stair climbing strengthens key lower-body muscles such as the glutes, quadriceps, and calves through repetitive weight-bearing activity.^[41] It also enhances bone density in the legs and spine by applying mechanical stress that stimulates bone remodeling and helps prevent osteoporosis-related bone loss.^[41] Furthermore, the activity promotes joint flexibility and supports weight management, with estimates indicating it burns approximately 0.11 kcal per step (or ~1.3 kcal per flight of 12 steps) for a 70 kg person, scaling with body weight (~0.0016 kcal/kg/step) and contributing to overall caloric expenditure in daily routines.^[35] Metabolically, stair climbing improves glycemic control by enhancing insulin sensitivity by about 24% and reducing postprandial glucose levels, making it particularly beneficial for individuals managing type 2 diabetes.^[4] It also positively affects lipid profiles, increasing high-density lipoprotein cholesterol while decreasing triglycerides.^[4] In terms of broader health outcomes, a 2021 UK Biobank study of over 15,000 participants revealed that climbing more than five flights of stairs daily was linked to reduced all-cause mortality (hazard ratio 0.91–0.93, or 7–9% lower risk) and a 12% lower risk of cancer mortality for those climbing 6–10 flights per day.^[18] Stair climbing supports mental health by triggering the release of beta-endorphins, natural brain chemicals that elevate mood, reduce stress, and alleviate mild symptoms of anxiety and depression.^[42] As short "exercise snacks," these bouts of activity fit easily into busy lifestyles, providing quick boosts in energy and cognitive performance without requiring dedicated gym time.^[42] Despite these advantages, stair climbing carries potential risks, particularly excessive practice that can lead to joint strain in the knees and ankles due to the high-impact loading on lower extremities.^[43] For older adults, it heightens fall hazards, which account for severe injuries like fractures in about 25% of cases and are a leading cause of mortality in this group.^[44] Overexertion may cause fatigue, while individuals with preexisting heart conditions or obesity should obtain medical clearance before starting, as vigorous ascent can exacerbate cardiovascular strain or balance issues without proper progression.^[43] Recent evidence reinforces these benefits for longevity; a 2024 analysis reported in the European Society of Cardiology's congress found that regular stair climbing was associated with a 24% reduced risk of all-cause mortality and a 39% lower likelihood of cardiovascular disease death among nearly 480,000 participants followed for 12 years.^[45]

Techniques and Safety

Climbing and Descent Techniques

Stair climbing ascent begins with alternating the leading leg on each step to maintain balance and distribute effort evenly across both lower limbs.^[46] Push through the heel of the trailing foot to engage the glutes and hamstrings effectively, providing propulsion while minimizing strain on the knees.^[47] Swinging the arms in opposition to the legs generates additional momentum, similar to natural walking or running gait, enhancing efficiency.^[48] For faster ascents, individuals can opt for a single-step pattern, contacting each step with alternating feet, which is more energy-efficient for moderate paces, or a double-step pattern, skipping every other step, which increases speed but demands greater muscular power.^[49] Descent techniques prioritize controlled movement to manage gravitational forces and reduce impact on the lower body. Step down heel-first onto each tread to absorb shock through the larger muscles of the legs, such as the quadriceps, which act eccentrically to decelerate the body.^[50] Using handrails provides essential balance support, particularly on longer descents, by allowing the upper body to assist in stability without altering gait mechanics.^[51] Avoid jumping or bounding downward, as this heightens joint stress and fall risk by bypassing the controlled eccentric loading that protects knees and ankles. Advanced variations build on basic techniques to target power and endurance. Plyometric bounds involve explosive jumps up two or more steps at a time, recruiting fast-twitch muscle fibers for improved athletic performance and lower-body explosiveness.^[47] Interval pacing structures workouts with short, intense climbs—such as 2-minute ascents followed by recovery rests—to enhance cardiovascular capacity without continuous fatigue.^[52] The StairMaster machine simulates real stair climbing in a controlled environment, allowing variations in speed and resistance to replicate outdoor progressions safely indoors.^[53] Optimal biomechanics during stair climbing emphasize an upright posture with the core engaged to stabilize the spine and pelvis, preventing forward lean that could strain the lower back.^[54] This alignment distributes load evenly across the hips, knees, and ankles during both ascent and descent phases. A rhythmic breathing pattern—inhaling during the ascent push and exhaling on descent—supports oxygen delivery and core activation, maintaining endurance over multiple flights.^[55] Training progressions for stair climbing should begin modestly to build foundational strength and confidence, starting with 1-2 flights of stairs per session to acclimate the muscles and cardiovascular system.^[56] Gradually increase volume to 10 or more flights over weeks, monitoring for fatigue to avoid overexertion, while focusing on consistent form. Incorporate stair climbs into running routes or circuit training—such as alternating flights with bodyweight exercises like squats—to develop endurance and integrate the activity into broader fitness routines.^[52]

Safety Guidelines for Adults

Before engaging in stair climbing, adults should conduct environmental checks to minimize hazards. Stairs must be well-lit, with a minimum of 100 lux at the tread level to ensure clear visibility, and equipped with non-slip surfaces such as treads or securely fastened carpets to prevent slips.^[57] Avoid using stairs that are cluttered with objects, wet, icy, or otherwise slippery, as these conditions significantly increase fall risk.^[58] Regular inspections for wear, such as frayed edges or loose steps, are essential to maintain safety.^[59] Personal preparation is crucial for safe stair climbing. Begin with a warm-up involving dynamic stretches, such as leg swings or marching in place, or a light walk for 5 minutes to increase heart rate and prepare muscles and joints.^[17] Wear supportive shoes with good traction and closed toes to provide stability and reduce the risk of foot slippage.^[1] Start sessions slowly, setting an achievable goal like 5 minutes twice daily and gradually increasing duration in one-minute increments to build tolerance without overexertion.^[60] To prevent injuries, limit initial sessions to 20-30 minutes and progress gradually to avoid strain. Monitor for signs of knee or hip pain, which may indicate joint stress, and stop immediately if discomfort arises; consult a healthcare provider if pain persists.^[61] Stay hydrated by drinking water before, during, and after climbing, even if not thirsty, to maintain fluid balance and prevent dizziness. Rest if feeling lightheaded, and incorporate breaks to recover.^[60] For special populations, modifications enhance safety. Elderly adults should adopt a slower pace, use handrails on both sides for support, and lead with the stronger leg when ascending to reduce fall risk and joint load.^[59] Overweight individuals benefit from progressive weight-bearing approaches, starting with short sessions and incorporating descending stair walking to improve fitness while minimizing impact on knees and hips.^[62] Those in post-injury rehabilitation should follow tailored techniques, such as using a cane or crutches alongside the weaker leg, and avoid stairs if unable to bear weight on the affected side until cleared by a professional.^[61] In emergencies, know fall response protocols: remain still to assess injuries, check for head, neck, or back pain, and call 911 if severe symptoms like loss of consciousness or inability to move occur; do not attempt to stand if spinal injury is suspected. Stair-related falls contributed to approximately 1 million emergency department visits annually in the United States, based on data from 1990 to 2012.^[63]^[64] Equipment tips further support safety. Opt for grippy footwear with non-slip soles to enhance traction on various surfaces. For high-volume climbing, consider optional knee supports or braces to provide joint stability, particularly if pre-existing conditions like arthritis are present, but ensure they fit properly to avoid restricting movement.^[61]^[65]

Development and Safety for Children

Stair navigation is a key gross motor milestone in early childhood, typically emerging as infants gain mobility around 6 to 9 months of age when crawling begins, allowing them to approach and ascend low steps using their hands and knees.^[66] By 9 to 12 months, many infants master descending by scooting or backing down on their bottoms, often turning around to face the stairs for safety.^[67] Between 13 and 18 months, toddlers start walking up stairs with hand support, such as holding a railing or an adult's hand, and may attempt descent by stepping down while facing forward, though backing remains common.^[68] By 24 months, children can often walk up and down stairs while holding on for support, and independent alternating foot use typically develops by 3 to 4 years.^[69] Infants employ instinctive strategies like the "scooting" or "crab-walk" method for descent, where they sit and slide backward using their hands for control, minimizing forward falls.^[67] As toddlers progress, they transition to reciprocal stepping with support, building confidence through repeated practice on short staircases.^[70] Stair-related injuries pose a significant risk to young children, with an estimated 93,000 cases annually treated in U.S. emergency departments for children under 5 years old, based on data from 1999 to 2008.^[71] For infants and toddlers aged 6 months to 2 years, common incidents involve falls due to rushing, carrying by adults, or obstructed visibility from toys and clutter on stairs.^[72] To mitigate these risks, constant adult supervision is essential when children are near stairs, particularly during unsupervised moments like nighttime.^[71] Installing sturdy safety gates at both the top and bottom of stairways, using hardware-mounted models rather than pressure-mounted or accordion-style ones, prevents unauthorized access.^[73] Caregivers should teach handrail use early, starting with the lower steps for practice, and avoid loose clothing or carrying items that could cause imbalance.^[74] Keeping stairs free of obstacles and discouraging play or running on them further reduces hazards.^[75] Encouraging age-appropriate stair climbing through supervised play supports motor skill development, enhancing leg strength, balance, coordination, and spatial awareness without forcing advanced techniques that could lead to frustration or injury.^[76]

Competitive Stair Climbing

Origins and Organizations

Tower running, also known as vertical running or stair climbing in a competitive context, is a sport centered on timed races ascending the stairwells of tall buildings or towers, with the emphasis placed on achieving maximum vertical gain in the shortest time rather than covering horizontal distance.^[77] Unlike traditional road or trail running, participants navigate continuous flights of stairs, often exceeding 1,000 steps, in environments that test both explosive power and sustained effort.^[14] Modern competitive tower running gained prominence with the Empire State Building Run-Up, the first major event of its kind in the United States, held in 1978 and organized by Fred Lebow, president of the New York Road Runners Club.^[78] This annual race up 1,576 steps to the 86th floor of the iconic New York skyscraper drew initial participants seeking a novel fitness challenge and quickly established the format for future competitions.^[14] The sport expanded significantly in the 2000s through European initiatives, including races like the Messeturm Run-Up in Frankfurt, Germany, and the Donauturm Lauf in Vienna, Austria, which introduced standardized timing and attracted international athletes.^[79] By 2009, the discipline was formally branded as "towerrunning," reflecting its growing organization and appeal beyond local fitness events.^[79] Governing bodies emerged to structure the sport globally, with the Towerrunning World Association (TWA), founded in 2013 and based in Austria, acting as the primary international authority responsible for world rankings, the Towerrunning Tour series, and event certification.^[80] In 2022, the International Skyrunning Federation (ISF) incorporated stair climbing by sanctioning its first world championships, held at the Jumeirah Emirates Towers in Dubai, thereby linking tower running to the broader skyrunning ecosystem.^[81] The sport's global footprint now includes diverse events across continents, such as the Taipei 101 Run Up in Taiwan and the annual Girnar Arohan Avrohan Spardha on Mount Girnar in India, which draws hundreds of competitors to its 5,500-step ascent.^[82] In the United States and Europe, longstanding races continue to thrive, while charity-focused firefighter climbs, like the 9/11 Memorial Stair Climbs organized by the National Fallen Firefighters Foundation, honor first responders and raise funds for survivor support programs.^[83] Tower running demands a unique physiological profile from its athletes, blending high anaerobic power for rapid step propulsion with aerobic endurance to manage lactate buildup over prolonged vertical efforts, often resulting in peak oxygen uptake levels comparable to elite endurance runners.^[84] Pioneers like Thomas Dold of Germany exemplify this, with Dold claiming a record seven consecutive Empire State Building Run-Up titles from 2006 to 2012, averaging finishes under 10 minutes 30 seconds and solidifying his status as a dominant figure in the sport's early professional era.^[85]

Major Competitions and Events

The Empire State Building Run-Up stands as a cornerstone of competitive stair climbing, inaugurated in 1978 as the world's first major tower race, where participants ascend 1,576 steps spanning 86 floors to reach the observatory. Held annually in New York City, the event in 2025 was held on October 8, attracting elite athletes and drawing over 225 competitors in timed heats.^[86]^[87] Similarly, the CN Tower Climb in Toronto, Canada, challenges climbers with 1,776 steps to the top of the iconic structure, serving primarily as a charity fundraiser organized by United Way Greater Toronto and WWF-Canada, with editions in November 2025 and May 2026 emphasizing community support for social and environmental causes.^[88]^[89] Global series provide structured competition through points-based tours and championships. The Towerrunning World Association (TWA) oversees the Towerrunning Tour, a premier circuit aggregating results from elite races worldwide, where Malaysian athlete Soh Wai Ching secured the overall title in 2023 with 25 victories across 28 events. The tour culminates in the TWA World Championships, such as the 2024 edition at Taipei 101, featuring 2,046 steps over 91 floors. Complementing this, the International Skyrunning Federation (ISF) hosts the Stairclimbing World Championships, with the inaugural event in 2022 at Dubai's Jumeirah Emirates Towers and the 2023 edition at Osaka's Abeno Harukas, where Japanese athletes dominated the podium across 60 floors.^[90]^[91]^[92] Regional events highlight local landmarks and charitable goals. In the United States, the Fight For Air Climb series by the American Lung Association spans multiple cities, including New York, Atlanta, and Philadelphia, with participants scaling skyscrapers like the Empire State Building to raise funds for lung health, featuring over a dozen annual editions. Asia's Frasers Tower Vertical Challenge in Singapore, running since 2022, involves 1,256 steps across 39 floors and supports disability initiatives, with Soh Wai Ching claiming victory in 2023, 2024, and 2025. The Hustle Chicago event, held at the former John Hancock Center, requires climbing 1,632 steps over 94 floors and hosted the 2025 Towerrunning USA Championship on February 23, combining competition with fundraising for respiratory health.^[93]^[94]^[95]^[96] Competitions typically employ formats centered on individual timed ascents, measuring performance by total time or vertical gain—often exceeding 300 meters in flagship races—with divisions by age, gender, and ability to accommodate professionals, amateurs, and first responders. While most focus solely on upward climbs, select events incorporate descent segments for added challenge. Post-2020, the sport has experienced sustained growth, with over 300 annual events worldwide facilitated by organizations like TWA, fostering greater participation among women and novices through inclusive categories and expanded calendars that included over 300 races in 2025.^[11]^[97]

Records and Notable Achievements

In the Empire State Building Run-Up, one of the oldest and most prestigious tower running events, the men's course record stands at 9 minutes and 33 seconds, set by Paul Crake of Australia in 2003. The women's record is 11 minutes and 23 seconds, achieved by Andrea Mayr of Austria in 2006. Suzy Walsham of Australia holds the record for most wins in the event with 10 victories between 2007 and 2019.^[98]^[15]^[99] Other notable achievements include multiple world championships by athletes such as Thomas Dold of Germany, who won four consecutive Towerrunning World Cup titles from 2009 to 2012. In recent years, Soh Wai Ching of Malaysia has emerged as a dominant figure, becoming the 2024 Tower Running World Champion by winning the Taipei 101 race and setting several Guinness World Records in 2025, including the farthest simulated distance climbed on a stair machine in one hour at 1.788 km.^[100]^[101]^[102] Guinness World Records also recognize endurance feats, such as the greatest vertical height climbed on stairs in 12 hours: 13,145.65 m (43,128 ft 8 in), set by Christian Riedl of Germany in 2021 at Tower 185 in Vienna, Austria. As of 2025, the one-hour vertical height record (male) is held by Ryoji Watanabe of Japan at approximately 1.65 km, though machine-based records continue to evolve with athletes like Soh Wai Ching pushing boundaries.^[103]^[104]
