Systems, devices, and methods for gathering data from a horse and rider and providing training to the rider are provided. In one aspect, for example, a method of training an equestrian rider can include performing a ride by an equestrian rider on a horse, and obtaining ride data from the ride, the ride data including video, inertial measurements, rider joint, head, torso, and/or limb information, horse joint, head, torso, and/or limb information, and at least one force measurement between the horse and the rider during the rider. The ride data can then be analyzed and at least one riding improvement to be made by the rider can be identified, and the at least one riding improvement to be made to the rider can be relayed to the rider to provide training for a subsequent ride.
