No 14 is not to old. If you are meaning human, you can start any age, or horse, that's still not old :)

I'm not made of money at all if you haven't got your own horse get a loan, or ride a horse in competitions for someone else. Then try and scoop up some county level prizes, and try and get a sponser. Keep aiming high!

no way is it too old,my horse is 13 and he acts live a 7year old , i know loads of horses in their 20's that are still jumping loads (and winning )
