Log (jump)

Log fences are obstacles that are jumped in equestrian competition, including in the cross-country phase of eventing and in hunter paces. Additionally, they may be met when fox hunting.

Log fences differ from the usual equestrian jump, which involves removable poles set in jump cups that are attached to a standard, because they are solid and do not fall down. Therefore, the horse may touch the fence, and even scramble over it, without penalty.

However, the fact that they are solid increases the risk that horse and rider will be injured if they make a mistake: the horse may hit it so hard that the rider is launched from the saddle or the horse may stumble over it and fall on landing. In the worst-case scenerio, a horse may hit the fence on his forearms, and somersault over it, which risks injury to the horse and especially the rider if the horse lands on her. Therefore, the rider must be especially proficient before attempting solid fences, to ensure he can approach them properly. Additionally, most riders get into a slightly more defensive seat when jumping log fences, and do not raise out of the saddle as high or fold as much, which will allow them to stay in the saddle if their horse accidentally hits the fences and stumbles on landing. This position is considered a fault when jumping show jumping fences, because the horse is always encouraged to bascule over the fence to help prevent him from touching and knocking the rails, and keeping the weight on his back encourages him to drop it instead. However, a "slightly" defensive position is not only acceptable when riding over solid obstacles, but in most cases ideal.

Horses will generally jump log fences quite well, as they look natural to the animal. It is best when designing and jumping such fences, however, to only ride over obstacles that have a larger log (rather than a thin, stick-like pole) as the horse will respect the jump and is more likely to jump it cleanly and boldly. Due to the risks, it is especially important to jump log fences in a forward manner with plenty of impulsion and good balance.
