You would get some cool shots using a tripod. It would make it a lot better if there was some variety and a mix between still and moving shots.
Overall, it wasn't a bad edit at all. I'm not to sure on the titles or the font you've used at the beggining. I think simple always looks better, maybe just have some plain white or black text for each riders first shot.
Maybe try and get some filler/ non skiing stuff in there too, might make the edit seem more fun and give it a bit of an atmoshpere.
Just whenever you next get out to film try and get interesting angles on things.
Sick edit and there's some really cool stuff in there.
