At one of my local trails on a section that is now gone, there was a small drop followed by a right turn. It was like ball bearings. I went down too fast to do anything but land on my shoulder. I had to do physical therapy for side whiplash. It wasn't an injury per se, but rather the little muscles tensed up and they were locked up.
I also went down on another trail, this time a section of off camber rock right after another small drop with leaves covering the trail. Something sent me slightly wide of the mark and I went down hard on my ride side with bruises on my hip, thorax and shoulder.
both of these I’m glad I didn’t put a limb down. I’ll take bruising over a broken bone.
my ankle break was a result of trying to put my foot down on a wall ride.
Sometimes it is better to go down with the ship.
