ride to time
Ride to Time, or Speed to Safety, is learning how to ride at a certain pace, and judge how fast your horse is traveling.
Pony Club riders need to know this when competing in show jumping or eventing. If you go too slow in a showjumping ring or on a cross country course, you will get time faults.
This is a discipline which can lead to work in the racing industry, as track riders and jockeys.
