Grace pretty please will you stop attacking every thing I say. I'm sure Tegan could see the humour in my post and didn't take offence. Neither did I the offence when Ana mocked me, I deserved it!
I am speaking about x-country from a position of knowledge as a course builder and one who organised the North West Area Trials. Yes, the fences are horrendous, but anyone who attempts to simply jump them at speed is going to come a cropper. There are choices to be made on every course. Some jumps you have to take a speed others you need to count strides, slow up, steady the horse etc. this is the reason that the riders, like jockeys, walk the course first to work out lines of approach, pacing, strides, etc.
Tegan is also correct that men and women compete on equal terms. No, there is no weight restrictions in eventing or show jumping.
Riding is a dangerous sport. Look what happened to Superman (sorry I forget his name) and that was 'only' show jumping.
