Draw reins and running reins

Draw reins and running reins are types of riding gear used to influence a horse’s head position. They work like a simple pulley: the rein slides through a ring on the bit, giving the rider more leverage to bring the horse’s head in and down. A regular rein attaches directly to the bit and is held by the rider; running or draw reins slide and can apply more leverage. In English and Western riding, the designs differ in details but use the same idea.

In English riding, many riders use two reins: a normal snaffle rein plus a running or draw rein. Sometimes riders hold both; other times they use only the running or draw rein with the snaffle rein slack. In Western riding, draw reins usually attach to the cinch rings and run through the bit rings to the rider’s hands. They are rarely used with the regular reins, and using a curb bit with draw reins is controversial and considered dangerous by many.

Draw reins are common in polo as well. They connect to the bit and to the saddle billets, giving direct action. In polocrosse, draw reins are mostly banned except in Market Harborough.

Running reins and draw reins are meant to help when a horse won’t respond to lighter aids. They should be used only until the horse gives the desired response, then stopped. They can help teach a horse to yield to rein pressure and lower its head, and may help heavy-mouthed horses. But they can become a crutch, making a rider depend on them instead of good riding.

Misuse can cause real problems: a horse can become hard-mouthed, travel on the forehand, overflex the neck, or develop neck and back pain from holding an artificial position. Over time, the horse may not engage the hindquarters or move freely. When used by skilled riders for short periods and with proper supervision, they can address specific issues, but they are not a substitute for good riding.
