In endurance, skin is a piece of equipment

Over eighty kilometres, what rubs helps decide whether the horse finishes. Where tack works on skin, how to cool properly, and what to check after the ride.

Showjumping lasts minutes, a dressage movement lasts seconds, endurance lasts hours. That changes everything. A wrinkle in the numnah that nobody notices on one circuit is a bald patch after eighty kilometres, and a bald patch can end a ride. Here skin is not cosmetic. It is a part that holds or does not hold.

Nobody is eliminated because the horse looked dull. They go out because something rubbed.

The girth area and saddle area, hour after hour

The trouble spots are well known: the girth area behind the elbow, the edges of the saddle panels, the ground under a breastplate. The question is not whether it rubs once, but how often. Over eighty kilometres a horse takes tens of thousands of strides, and every one of them drags skin against kit.

• A hand over the girth area and back before tacking up: sand and grit out.
• Keep girth and numnah clean, yesterday’s dried sweat is sandpaper.
• Pull the numnah up into the gullet, wrinkle free, every time you mount.
• At every gate, feel along the lines where kit sits.

Sweat and salt turn friction into a problem

Horse sweat carries a lot of salt. Let it dry in the coat and the crystals stay behind, working like fine sandpaper under any strap. Add the dust of the track. That is why endurance crews do not only cool, they wash: water over the lines where kit sits, scrape it off, and the girth lies on skin again, not on salt.

Cooling at the vet gate, from the bottom up

Time counts at the gate: the pulse has to drop below a set limit before the horse is presented. So cooling is quick and follows an order, legs and the underside of the neck first, then the chest, then the big muscle masses. Working from the bottom up gives the horse a moment to meet the cold water, instead of a bucket on a working quarter.

The second principle is scraping. Water standing on the coat warms up and insulates. So water on, sweat scraper off, water on again, until what comes off stays cool. And keep walking: a horse being led cools better than one standing still.

Bridle, boots and the look over afterwards

On the head it is noseband edges, cheekpieces and anything buckled too tight. Boots are the other running argument: they collect sand, and sand under neoprene for hours is a reliable rub. Plenty of riders go without, or rinse them out at every gate. After the ride you work through the horse: girth area, behind the elbow, saddle area, head, legs, once with a flat hand and once with your eyes.

An endurance horse does not finish because it is tough. It finishes because somebody took every strap seriously.
