Warm up your horse before the start of the ride. Take it easy and do not try to keep pace with the experienced horses and riders. Experienced, well conditioned horses can complete a ride in half the time of a new horse. If your horse is excitable and hard to control at the start of a ride, wait until the other riders leave, then start out slowly. Then increase the distance, speed and number of times per week over a period of three months or so until the horse reaches peak condition.
Conditioning needs to be continued throughout the ride season.
It is a good idea to get a stethoscope and learn what your horses normal working and resting heart beat is. Find out how long it takes to recover after a strenuous workout. You should handle your horses feet, mouth, tail, take anal temperatures and generally learn every aspect of their bodies so you know when there are anomalies. You should be able to discuss all anomalies with the vets, as well as point any areas of concern to them. Protection of the horse is essential to ensure a long term partnership.
