Time To Change The GameRunning 160 kilometres on unfamiliar terrain is always a challenge, no matter how fast you do it. Jim Walmsley takes this challenge to a whole new level by trying to cover the distance faster than anyone thought possible. By doing so, he's able to truly push the boundaries of human performance. "I'm taking what I know from the track and entering the totally-unknown world of ultra-trail running to find out how I can take the sport to a new level of performance - one that has never been seen before."
