Rachelle isn’t actually a pro, but a pretty advanced rider nonetheless. She used to work for Pinkbike and now works for GT and was kind enough to show us around Whistler on one of her bikes not long before the crash.
Glad she’s OK, she’s a super nice person! Sounds like she made it out with only a broken arm.
Whistler has been incredibly dry, so my guess is that the rock slab is very dusty/slippery, steeper than it looks on video, and she got a bit off line, which happens to all of us.
