I came off my pony today. We are crap at corners in the arena in canter- she always cuts the corners. We've been working on this with my instructor and it's part pony and part my fault. Anyway today she cut the corner in canter and nearly went over a jump wing that was in the arena that I'd mounted off. She had to quickly change direction and I fell off. Nothing was damaged other than my ego but I did bash the bottom right hand side of my helmet on the floor. Not hard but I felt it. I don't have any signs of concussion. My question is whether you would replace your helmet (knowing how much this costs!) or not?
