Accept that people might call them hamsters. "We always make the joke too: 'Come on, let's do the hamster'," says Oriol Antolí (Terrassa, 1983). A few days ago, he achieved the Spanish record for Backyard Ultra, a discipline that comes from America. It consists of running a 6.7-kilometer circuit with a start every hour on the hour: the minutes left between reaching the finish line and the next starting gun are used to eat, rest, and even sleep. Whoever lasts the longest wins, like in the Japanese movie Battle Royale. It's a test of endurance, not speed. The discipline is "very successful" and is becoming increasingly popular in Catalonia: the third edition of the Backyard Ultra de Terra Endins brought together 200 participants in Torelló at the beginning of May.
