Lots of great input here ! I agree that the long periods of the really fast & fun extended trot may contribute to injuries ! I try to find the medium trot that is not real concussive, either ! I also think trotting fast downhills is a killer on their legs ! I have been pooh poohed for years for riding conservatively at many rides, but I salute all who do & keep racking up the miles on their still sound horses ! Bottom line is we all would like to win, but it is a lot riskier ! - Hiking Heidi Helly
