What about the foot issue? It might be possible to substitute the Sat starts with some explosive med ball throws from your block settings to save wear and tear on the foot for the meet. Place a mat in front of the blocks and throw out while pushing off the blocks and land on the mat without drawing the back foot forward (which would smash your knee into the ground!) If you don’t have a mat, secure the blocks into the grass, otherwise you’ll kill your wrists…
