Unless you're trying to nail gold in each and every event I don't see how its frustrating at all. What is it thats getting to you?
If it was I certainly wouldn't be playing it to chill, which I do, and have, the past few nights while listening to a hardcore history podcast. Just go your own way, without doing events, and its pure downhill goodness. Run the events when you want to test yourself. Some are easy, some are frustratingly difficult, depending. But even then the instant restarts and instant teleportation anywhere across the mountain helps a lot.
Basically, what I do is find an event that starts just about as high up as I can get for a particular side of the mountain. Then I just avoid going through the circle that starts the event and see if I can find my way down, at speed, until I reach some frozen lake far below, or else I reach the edge of the map. If I run into any problems - like blind cliffsides filled with jagged rocks (pretty much a setup for the basejumping and gliding events) I just hold down the triangle for 2 seconds and whoosh, I'm back up at the top where I might see whats to the left, or right, or behind, or whatever. You can find some nice, long runs and slip into a smooth zone.
