I bought my mare a few months ago, she is nice and sensitive but very level-headed and calm at the same time (5 year old paint). Before I bought her she was only being ridden maybe once a week or less, so she was quite green and her muscles were not properly developed.
Since then I have been riding her about 3x a week, with a LOT of improvement and she was still happily working.
I recently moved her to a better facility where she is much happier and gets to walk/run around all day at will, I find she has much more energy but normally it is easy to put it to productive use.
Today, however, I took her out and she had a nice forward walk but as soon as I asked for the trot it was the fastest trot she could possibly muster and she kept breaking into the canter. She was calling for the other horses once in a while which is NOT like her at all, she is very good about being alone. I let her get some of her steam out and do her thing until she was ready to come back to me and then I tried to regulate her pace with my seat and my posting but it only lasted for maybe a circle and then it was frantic running again..
I'm wondering if this could be caused by soreness? The last 2 weeks I have been riding her at least 5x a week (not overly hard but still) and also yesterday we went for a long forward walking trail with lots of hills which she is NOT used to...
I'm just afraid I'm losing my nice calm girl, I am hoping there is something else going on since after my ride I led her out on her own quite a ways away from the barn by noisy traffic, etc. and she was just fine without the other horses..
It's so hard not to let my frustration get the best of me when she is just going going going with no response to anything I am asking of her but I know getting strong with her will only make it worse..
Any help would be great!
