So there i was just coming up to some lights about to go green, on The Mall, and there was a fixie in front of me. I cruise past him and accelerated away...up to 25,...26,..... 27mph. I thought "That'll ensure i beat him to Trafalgar Square"..at which point he FLEW past me as if i were standing still!! He must have been doing 35 mph at least.. Nearly 20 years i've been commuting, he was the fastest i've ever seen! "RESPECT"
