Talk:Mountain running

Fell running?
How does mountain running differ from fell running and trail running? Maybe this article should merge with fell running? Clarification is badly needed here. Rwood128 (talk) 20:08, 7 December 2018 (UTC)

Mountain running
I've been looking for some info on mountain running and differences between trail and sky running and it seems 1.skyrunning is a type of mountain running 2.there are two version of mountain running race: uphill/downhill race and uphill race. In the former runners run from the bottom of the mountain/hill to the top and than return. This differs from the trail running where there are numerous ups and downs on the route. 213.149.61.163 (talk) 19:54, 23 December 2018 (UTC)
