William Sichel is one of the world’s best multiday runners. Now, at the age of 66 he’s completed several 6-day races over 800 k (500 miles) and he’s also finished the famous 3100 mile race in New York. He has a background as a semi-professional table tennis player and already back then, he used unconventional training methods. When he stopped playing table tennis, simply because it bored him, he went into running and ran his first marathon on 2:43. He then ran a 100 k and was surprised that he won this competition, which was also the Scottish Championships.
