14 Most Steps Climbed in a Single Attempt
Stair climbing challenges represent some of the most demanding endurance feats in the world of athletics and record-setting. While most of us struggle with a few flights of stairs, elite climbers tackle thousands of steps in single attempts, pushing the boundaries of human endurance and mental fortitude. These vertical marathons test not just leg strength but cardiovascular capacity and psychological resilience.
Here is a list of 14 remarkable stair-climbing achievements that showcase the incredible heights humans have reached in a single attempt.
Empire State Building Run-Up

The annual Empire State Building Run-Up challenges participants to climb 1,576 steps across 86 floors. Elite climbers typically complete this iconic vertical race in under 10 minutes, with the current record standing at just over 9 minutes.
The narrow stairwell forces competitors to develop specialized techniques for passing and maintaining momentum throughout the ascent.
CN Tower EdgeWalk Stair Climb

Toronto’s CN Tower presents climbers with 1,776 steps spread across 144 floors. This charity event attracts hundreds of participants annually who tackle the concrete spiral staircase that winds its way up one of the tallest freestanding structures in the world.
The fastest climbers complete the challenge in approximately 13 minutes, though most participants take significantly longer.

Taipei 101 Run Up

The Taipei 101 tower features 2,046 steps across 91 floors, making it one of the most challenging vertical races globally. What makes this climb particularly difficult is the combination of step height and the building’s altitude, which creates air pressure changes noticeable to climbers.
The record for this climb stands at just under 11 minutes, an achievement requiring extraordinary leg power and oxygen efficiency.
Stratosphere Tower Stair Climb

Las Vegas’s Stratosphere Tower challenges climbers with 1,455 steps in a uniquely shaped stairwell. The distinctive feature of this climb is the uneven spacing between landings, which disrupts rhythm and forces climbers to constantly adjust their pace.
Participants often report the final 200 steps as particularly grueling due to the thinner air at the tower’s upper levels.
Eureka Tower Climb

Melbourne’s Eureka Tower presents 1,642 steps across 88 floors of increasingly difficult climbing. The stairwell narrows as climbers ascend, creating a psychological challenge as participants feel increasingly confined while fatigue sets in.
Competitors often train specifically for the unique layout of this tower, which includes several sections with steeper-than-standard steps.

Milad Tower International Climbing Competition

Tehran’s Milad Tower features 1,805 steps and presents climbers with one of the most technically challenging stairways. The unusual design includes several sections with curved staircases and variable step heights, making it impossible for climbers to establish a consistent rhythm.
Elite athletes typically complete this climb in approximately 15 minutes, though the record stands closer to 12.
Eiffel Tower Stair Climb

While not the tallest structure, the Eiffel Tower’s 1,665 steps present a unique challenge due to their open-air design and irregular spacing. Climbers must contend with weather conditions, including wind and sometimes rain, adding an environmental factor absent in enclosed stairwells.
The exposed nature of the climb creates additional psychological challenges for those with a sensitivity to heights.
Willis Tower Stair Climb

Chicago’s Willis Tower (formerly Sears Tower) features 2,109 steps across 103 floors of consistent, well-maintained stairs. The challenge here comes from the sheer volume of steps combined with the consistent grade, which quickly leads to muscle fatigue without any variation to provide relief.
Firefighters regularly train on these stairs, often completing the climb in full gear weighing over 70 pounds.

Sydney Tower Eye Stair Challenge

With 1,504 steps, the Sydney Tower climb offers panoramic views through occasional windows that either motivate or distract climbers. The stairwell features several sections where the incline changes subtly, creating additional strain on different muscle groups throughout the climb.
Participants often report the psychological boost of glimpsing the harbor views provides crucial motivation in the later stages.
Cologne Cathedral Tower Climb

This historic cathedral presents 533 steps of medieval architecture, featuring narrow, winding stone stairs that prevent modern climbing techniques. While containing fewer steps than modern skyscrapers, the ancient, uneven stone steps and tight spiral design make this climb particularly challenging on ankles and knees.
The constrained space prevents participants from establishing the rhythmic climbing pattern possible in modern buildings.
Swissotel Vertical Marathon

Singapore’s Swissotel features 1,336 steps across 73 floors with minimal landing space between flights. The continuous nature of this climb with few rest opportunities creates a particular challenge for pacing strategy.
Competitors must decide whether to push through without breaks or incorporate micro-rests at the minimal landings provided.

Niesen Stairway Run

Switzerland’s Niesen mountain railway stairway contains an astounding 11,674 steps, making it the longest stairway in the world. Unlike urban tower climbs, this outdoor staircase follows the path of a funicular railway up a mountainside, exposing climbers to changing altitude and weather conditions.
Only opened for the annual race, this climb takes elite athletes approximately 1.5 hours to complete.
Landmark 81 Skyrun

Vietnam’s tallest building challenges climbers with 2,383 steps across 81 floors of increasingly difficult climbing. The stairwell design features inconsistent lighting that creates visual adaptation challenges as participants ascend.
The combination of height, humidity, and architectural design makes this one of the newest and most demanding stair climbs on the international circuit.
Mount Everest Base Camp Stone Stairways

While not a single staircase, the combined stone steps leading to Everest Base Camp total approximately 3,500 steps spread across multiple stairways at high altitude. Climbers must contend with decreasing oxygen levels and extreme temperature variations while navigating these ancient stone paths.
The combination of altitude sickness, weather exposure, and physical exertion makes this multi-day step challenge among the most demanding in the world.

The Vertical Horizon

What makes these stair-climbing achievements so remarkable isn’t just the physical accomplishment but the mental fortitude required. Modern stair-climbing competitions have evolved from practical building evacuation drills into legitimate athletic events with specialized training methods and equipment.
The sport continues to grow globally, with more buildings opening their stairwells for both competitive and charitable climbing events each year. These vertical challenges remind us that sometimes the greatest human achievements aren’t about covering vast horizontal distances, but about the determination to keep climbing upward—one step at a time.
