I've been training for my first marathon for several months now. A few weeks back I started speed work on one of my days. After about a mile of going good and hard I get a side cramp in my right side. The only way I can get rid of it is to walk for a bit, and even then it will come back after I've been running for a while again. This does not happen with my medium or long runs. I've been watching my hydration and nutrition and I make sure not to eat for at least an hour and a half before the run. Any ideas>
The best known cure, in my opinion, for a side stitch, is to put your hand on your head, and blow all your air out. Once you have done this, blow even more air out . Then when you inhale, try to do it smoothly and slowly. This is more of a quick-fix than prevention, and it isnt perfect, but it could help if you are in trouble.
Yeah I have round that the best way to cure a stitch is to breath out as fully as you can and repeat. if that dosnt make it go away quickly then you might need to think or something else though...I had an aweful stitch during a half marathon once and this trick literally saved my PB!
I'm not sure what speedwork you're doing, or how you determine your pace. But slowing a little may help prevent the stitch from starting. Another technique that may help keep it from starting (and works for me) is closely related to the tips above: belly breathing. Make sure to breathe with your belly, your diaphragm, not just with your chest/lungs. It may take some practice but it should help.
