In a remarkable display of endurance, British cyclist Alex McCormack has set a new provisional seven-day distance world record, covering an astonishing 3,826.47 kilometers. This feat was achieved through relentless cycling along a 150-kilometer out-and-back route along the Moselle River in Koblenz, Germany. Over the course of seven days, McCormack averaged 18.5 hours per day in the saddle, culminating in a monumental 727.75-kilometer ride on the final day. (media-centre.canyon.com)
The previous record stood at 3,813.81 kilometers, set by Arvis Sprude in 2024. McCormack’s achievement surpasses this by 12.66 kilometers, though it is still pending ratification by the World Ultra Cycling Association (WUCA). (media-centre.canyon.com)
Throughout this grueling endeavor, McCormack faced unseasonably cold, rainy, and snowy conditions, which significantly impacted his performance. The adverse weather forced him to limit rest periods to only a few hours each day, dedicating the remainder to continuous cycling. Despite these challenges, McCormack’s determination and resilience were unwavering. (media-centre.canyon.com)
Canyon team lead sports marketing Markus Schweikert recounted the intense final moments of the attempt:
“As soon as the clock hit seven days, he was about 4km from the end [of the 150km loop] and he stopped dead – he had absolutely nothing left, he was empty.” (media-centre.canyon.com)
McCormack’s support team played a crucial role in his success, managing logistics, nutrition, and recovery. They ensured he consumed an estimated 14,000 calories daily to sustain his energy levels. Team member Harry Dowdney highlighted the difficulties posed by the weather:
“The biggest thing for the support crew was to wake Alex after short naps and make sure he kept eating and drinking. There was no way he could replace those 14,000 calories. We had to constantly remind him to eat and drink, passing him food as often as we could.” (media-centre.canyon.com)
For this record-breaking attempt, McCormack utilized a custom Canyon Speedmax CFR, a time trial bike equipped with high-profile carbon wheels, integrated hydration systems, and a top tube bag. This setup was designed to minimize aerodynamic drag and maximize efficiency over the extended distances. (media-centre.canyon.com)
This achievement adds to McCormack’s impressive list of ultra-distance accomplishments, including victories at the Atlas and Hellenic Mountain Races in 2025 and the Highland Trail 550 in 2024. Additionally, he set a Double Everesting World Record in 2025, climbing 17,732 meters in just under 21 hours. (media-centre.canyon.com)
Looking ahead, McCormack is preparing for a summer campaign targeting the Triple Crown of U.S. ultra-distance events: the Tour Divide, Colorado Trail Race, and Arizona Trail Race. A documentary chronicling his latest challenge is also set to be released later this year, offering an in-depth look at the physical and mental demands of ultra-endurance cycling.
