I recently spoke with a marathoner who's prone to cramping in long training sessions. He described the sheer terror of race day, explaining how difficult it is to find the right balance: pushing hard enough to hit his goals, while holding back enough to prevent a race-ending cramp.
Kyle Edmund, who was recently forced to retire from the Australian Open due to leg cramps, spoke about his frustrations after the tournament, "I'm disappointed with it obviously because it's not my tennis that's let me down because my tennis is good enough to do it, it's my body that's let me down."
Edmund is one of the first athletes I've heard to address the mental component of muscle cramps as well, "You can't play full out because you lose confidence in your movement and when you do move you start to cramp up again. It was the same situation I felt in Davis Cup where I couldn't do anything. To beat these guys you have to be 100 percent."
