Hello -- one of the top runners on the XC team that I coach keeps getting "side stitches" -- those cramps in the side/abdomen that only seem to happen while running. He is a senior and runs all three seasons, so he's no newbie and we can't figure out why this is happening all of a sudden.
He ran well in a preseason 5K scrimmage, but since then, every time he tries to run, he ends up getting a side stitch. He has yet to run well in a regular-season meet or workout. He even gets them during warm-ups and easy runs sometimes.
He should be our #2 guy, if not our #1, but as it is he's hovering near the bottom of our Varsity results. With this going on with him and our presumptive #3 out with a minor calf injury, I'm eager to find a solution.
I know that sometimes eating too soon before a race can cause this, but he had breakfast at around 7 today and ran at 10 -- and still got a side stitch. I doubt it's abdominal weakness, as we've been doing core consistently for four years (and this never happened to him when he was a Freshman and came onto the team without having done any core before).
Sometimes this can be caused by going out too fast, but today I had him run a conservative first mile... and he still got one.
Any ideas? I know it could be related to his breathing, but other than that, I'm lost as to how to address this.
Thanks in advance.
