For jumps, repetition is huge. I had taken a few bike park lessons, but overheard some guys talking on the gondola saying if you ride jump trails for 10 days, you'll be good at jumping. Started just lapping jumps all day. Went from not clearing 60% of Crank it Up to comfortably riding Dirt Merchant pretty quickly (pre Pro-Line). I still can't bunny hop FWIW. It's pretty hard to beat the progression of the Whistler park given the amount of runs and predictably built jumps. It's just built for progression with Crank It Up (More)/A-Line.
I'm hoping to get some cornering coaching this summer if anybody can recommend somebody in Whistler/Squamish/Pemberton.
