Limited Distance rides of 40 to 55 km are great for riders new to endurance riding or riders who desire to ride shorter distances. The same rules apply as in the longer endurance distances, except the rider has up to 30 minutes upon reaching the finish line to achieve an equine pulse parameter of 60 bpm and pass a post-ride evaluation by a control judge. Equines must be 48 months of age to compete in LDs and it must be run in conjunction with an Endurance ride.
