Fasten All the Buckles or Snaps
Do up the throatlatch of the bridle. This endurance bridle has a snap at the throatlatch. Most traditional leather bridles will have buckles. So that your horse can flex his neck properly don't do the throatlatch up tightly';leave about 4 inches slack. You should be able to slip your hand, palm flat down, between the strap and your horse’s jaw.
Unless you are using a figure-eight, flash, or grakle noseband, leave about 2 fingers width between the lower jaw and the strap. If you are using a curb bit, you’ll need to do up the curb chain or strap. Leave the width of two fingers between the chain and the lower jaw. Leaving the chain too loose or tight can make the action of the bit or the chain more severe. If the bit has a port it could rotate up and hurt the top of the horse’s mouth.
Slip the halter off, tidy your horse's mane and forelock and you are ready to go.
