I agree. When I first moved from 80m - 100m hurdles, I started training at 100m height and it scared me and I became demotivated because they felt so high and my strides as a result got out and I started stuttering because I can’t lead with both for 4 strides so was trying to make 5. Couple of months later, did an 80m race to find that the striding was stupidly short, I had too much speed and was stuttering because I could only fit 2 strides in beacuse I’d picked up so much speed. If they’d been set for 100m I’d have been fine. When I was doing 80m we used to train low and just do the drills - I have the speed so work on the techqniue and then the package goes together just before the season kicks off.
