Robin Gemperle Sets Standards in Ultracycling
Robin Gemperle: Revolutionizing Ultracycling
Robin Gemperle, an athlete from Aargau, Switzerland, is currently making waves in the world of ultracycling. As of August 21, 2025, he is competing in the Silk Road mountain Race in Kyrgyzstan, a grueling 1954-kilometer route with 27,938 meters of elevation gain, largely on gravel roads above 2500 meters.
This race is considered an icon in ultracycling – a discipline focused on completing enormous distances in the shortest time possible – and is known for its extreme weather conditions. Gemperle’s approach to the sport is innovative; he prioritizes relaxation and sleep, averaging four hours of sleep per night even during races, believing it allows him to maintain a higher pace than competitors who attempt to minimize sleep. He focuses on performance metrics like wattage and pulse control, similar to professional road cyclists in events like the tour de France.
Gemperle’s success is rapidly changing the landscape of unsupported ultracycling, where athletes are prohibited from receiving outside assistance – no vehicles, supervisors, or drafting. Participants must carry or purchase all necessary supplies. He previously competed in the Transcontinental Race, finishing in the top 10 on his first attempt and second place on his second, just behind Christoph Strasser. Last year, he won the Transcontinental Race, surpassing Strasser.
More recently, Gemperle completed the Tour Divide in North America in 11 days, 19 hours, and 14 minutes, covering 4400 kilometers and 33,000 meters of altitude, setting a course record (though not officially recognized due to a slightly altered route caused by forest fires).
Before dedicating himself to ultracycling, Gemperle was a talented mountain biker and initially studied architecture.He transitioned through fixed-gear racing before discovering ultracycling, and now works part-time while pursuing his athletic career. While some view his professionalized approach as disruptive, many find him inspirational.
