I am pretty new to barrel racing, and so is my mare...
And I need help!
She was previously a pleasure horse but she has so much gaming potential.
She likes to run, but that is begining to become a problem.
Whenever we enter the arena she feels the urge to go full speed. Whether there are barrels set up or just and open arena.
If i try to hold her back she tends to rear or buck.
I have seen some horses become extremely antsy and hyper when they are in the arena and I definatly DONT want that to happen with me and my horse.
Not having a trainer at the moment makes it hard to improve..
Does anyone have any ideas or advice that could help me with this issue?

my horse tends to get very hot as well. i ride everyday of the week. i make sure that at lest 3 of the 7 days im riding has nothing to do with barrels . take her back to pleasure land. and focus on being in the arena around the barrels but pay no attention to them. get her to focus on you and not them. if you live some where you can go on a trail ride or something, give that a try. make her life about more than just barrels and she will eventuall get the idea.
