What is a bending line and how do you ride it?

A bending line is a related distance between two fences that are not set on a straight line — the path from the first fence to the second requires the horse and rider to follow a curved track rather than a straight one, which affects both the number of strides available and the approach quality to the second fence depending on which arc of the curve the rider chooses. Bending lines introduce a strategic dimension that straight related distances do not have: the rider can choose to ride the inside of the curve, which shortens the distance and requires fewer strides or a slower pace, or the outside of the curve, which lengthens the distance and requires more strides or a faster pace. The correct choice depends on the specific fence heights, the horse's natural stride length, and the number of strides the course designer intended — information that the course walk provides by allowing the rider to walk the distance on both the inside and outside arc and feel which track produces the most comfortable stride count. Riding a bending line correctly requires early commitment to the chosen track: the rider must begin curving toward the intended arc immediately after landing from the first fence rather than drifting straight before turning, because the distance from landing to takeoff on a bending line is a function of the arc chosen, and committing late to the arc changes the effective distance. A common bending line error is riding straight between the fences rather than committing to the bend, which typically produces either too many strides if the horse drifts toward the outside arc, or an awkward approach angle if the rider attempts a late turn toward the second fence. Bending lines also test the rider's ability to maintain the horse's balance through the turn while preserving the pace and impulsion needed for the second fence.
