The rules: No trail can be ridden twice, and no e-bikes. This is what the two amateur mountain bikers Silvan Marfurt (1988) and Ralph Van Den Berg (1985) stuck to yesterday when they set a new world record. In 16 hours, the two conquered a descent of 20,845 vertical meters in Davos Klosters. Hardly surprising! The Swiss biking destination is known for its almost infinite number of single track trails and its Bahnentour, or “cable car tour,” which is what inspired this world record. “The Bahnentour, with its descent of about 10,000 vertical meters, is my favorite Davos Klosters tour. I rode it several times to prepare,” stated Ralph Van Den Berg.
