Hi guys 
There's a charity run at my school soon and its going for 24 hours but you don't have to be on the track the full time. Anyway I was wondering is it possible to walk for the full 24 hours straight? Or how long can the average person possibly walk for? Thanks!
(By the way the track is quite easy, mostly flatland)
