I have a 15.3 hh Thoroughbred that I am learning to jump on. During lesson my instructor set up a line with perfect striding making it easier for me to concentrate on my position and not worry about the strides. Someone moved the jumps recently and I would like to set the line back up but I don't know how far apart the two jumps should be. I trot up to the jump and my horse has one good canter stride before the second jump. Can anyone help me on figuring out the steps or feet?
