What a guy! The great Wade Duncan, an American cycling to Alaska. Nuts in the nicest possible sense. He ruptured his achilles tendon a few days before. Saw a doctor and was taking huge quantities of painkillers and anti-inflammatories. Then, he realised, that if he kept his foot pointing downwards, he was painfree. So that morning he gaffa-taped his foot and ankle so it stayed pointing down. It worked. Previously he'd been cycling with just his left leg! Hope you reached Alaska Wade if you ever read this!
