Alex McCormack is 28 years old and has just redefined what a human body can endure.

For seven consecutive days, between March 26 and April 2, this British cyclist rode the same flat 150-kilometer route along the Moselle River in Koblenz, Germany, over and over again. Snow, rain, temperatures close to zero. Up to 18 and a half hours a day on the bike, with his neck and hands battered by constant friction.

At the end of the seventh day, the counter read 3,826.47 kilometers: more than the entire Tour de France covers, but compressed into a single week. He beat the previous record by just 12.66 km, a razor-thin margin that can only be explained by years of extreme training, including an Everesting feat in under 21 hours. The record is now awaiting validation by the World Ultracycling Association before reaching Guinness World Records.
