This week Kilian is stepping down from the mountains, where he’s considered as the best trail runner in history, to run for 24 hours on a track. How far do you think he can go? The longest distance ever run in 24 hours is 303.56km back in 1997, which Kilian says is "absolutely wild!" Exact dates of the attempt are still being decided, we’ll announce it in the next few days - stay tuned.
