17y.o barn owner

At least 7

Ohkay if someone ever told me that I had to ride their horse i'd tell them to stick it where the sun don't shine. That's YOUR horse. YOU are allowed to ride it whereever you please. (Property permitting) No one ownes the road so you can ride your horse on the road. And 20miles is a long way even walking and you horse /will/ get tired and sweaty im just warning you. She can't make you ride her horse or not ride yours. You give back enough with helping her in the barn, if she doesn't have time for all her horses then maybe she shouldn't have so many. I would stop riding hers all together and focus on my own if I were you. Your horse wants your attention and some snotty 17yr old who has too many horses shouldn't stop you from giving it.

Well the horses get about and hour break. B/c its 10miles to get to dominos farm(its a place with farm animals) and stay for about an hour helping around with the animals. And its 10 miles to get back.

Can you pony one horse and ride another? You could even switch off whose ponying and or point out that her horses really do need exercise so you will pony one and ride yours, and she should pony another to fully make use of your time. She's 17, maybe responsible enough to make sure horses are fed, cleaned, watered, and handle minor squables, but probably not always fair and diplomatic. If you really want to fight fire with fire, insist on riding your horse, if she refuses to go, go anyways (if your safe riding alone on this type of ride), then the next time you know she is going to be riding on the road, tack your horse (in his stall if you really don't want to tip her off) and just insist you ride with her. She can't control the ten foot radius around her and say your can't ride there. Just leave when she does, then what choice does she have anymore. Sounds like you are learning from her and kind of a working student, and sometimes that requires doing what the trainer wants done, not what you want done. I woud try ponying first though, and you can politely insist that you trade off or both pony a horse to make it fair.

Poying a horse would be too much trouble, because we jump ALOT and go to through lake and all that

If you are talking about a five minute warm up, then you should have no problem with my post. I said excessive, not a five minute period to get the kinks out. Lunging in small circles for extended periods of time is hard on their legs, especially for horses who aren't used to using their body correctly.

I thought it was a road ride? Im confused now. Is it a road ride or something else. Im not sure thre are jumps and lakes on roads.

Its both, We cut through trails to make it faster. It was super fun and it rained so that make it even funner!!!!!
