My mare Angel is a 7 year old OTTB. Thus far we had only jumped 2-3-2'6. I think we did something 2'9 once when on a ride at a local hunt at least a year ago. On a whim I decided to try something bigger. So yesterday she cleared a jump that I think was 3'4- 3'5 ish- that is actually the highest either of us have ever jumped. Nice to know she can do it. Will continue with the low stuff for now- we are hoping to do first BN in September. I know that a cow can jump 4' but I was still very proud of my little Angel. Hope she has what it takes to be an eventer!
