Met some friends to ride fat bikes at St. Ives golf course. Part way through the first segment, I tipped over on a hill and shortly afterwards, by saddle separated from the seat rails. I retrieved the saddle and continued, sitting on the rails (not comfy and too short to the pedals) and pushing on. Shortly after that I caught my leg on one of the exposed seat rails and ripped my Gore-Tex pants. I was DONE and left once the trail circled back to where we parked the cars. The other continued their ride without me holding them back. Not my best riding experience but not life threatening either. On the way home, a deer ran out in front of the truck and I knew calling it quits for today was the right decision!
