There is a lot of very honest feedback here. We all know that a horse that is willing, safe and compatible with it's rider is a must. Nearly any horse can do endurance given enough time, conditioning and management. However, if you don't currently have a horse and want to start looking more at the conformation side of things this may help. Please note - this is what we look for in Australia for our hot and humid conditions, your conditions may vary the type of horse you are after.
Arabians and part Arabians are often sought after, as well as the hardy Brumby or Mustang types. Appaloosa's also tend to have lower heart rates.
- The lower the resting heart rate the easier it will be for you to strap your horse back to below the parameters. Unlike humans, horses resting heart rate does not get significantly lower the fitter they become.
- Good solid feet are a must. The bigger the load bearing surface the better. No hoof = no horse.
- Wide nostrils for oxygen uptake and cooling.
- A Wide chest for organs - lungs and heart.
- Height can be an indicator for a longer stride = easier ride & less strides is economical.
- Solid well formed legs.
