i have my first horse show in two weeks from today. i have only beeen riding about two months, but about 6 months 5 years ago. it is just a walk/trot class and i am using one of the stable's horses. my main problem is keeping my heels down. i really want to learn how to, if there are any exercises or anything! also any show tips would be helpful. i have to wake up at 4am! leave by 5, get to my trainers house by 6am, then bathe, load, etc and be at the show by 8am!
