Running martingale, club model, havana, horse size: the rings guide the reins and limit a high head carriage, with a softer bearing action than a standing martingale — the reins slide through the rings, the hand keeps some slack. Classic use on the young horse under saddle. Adjustment: the rings should reach wither height when the reins are tightened — a running martingale set too short knocks the mouth at every movement.
