Cramps in my side

I have been trying to figure these out as well.  I have decided that its either a lack of run fitness or maybe that it has to do with eating too close to the race but I'm still not sure.  They are debilitating though and are a huge PITA!!

If you are talking about side stitches I've suffered on and off ever since I began try-ing. I get those more frequently when I eat/drink too close to a run or too much during a race. The way I can battle them is by breathing; if the side stitch is on the right side I inhale when my left foot hits the ground and exhale when my right foot hits the ground (I usually breathe every 2-3 steps depending on speed). If the side stitch is on the left side I do the opposite. If you do this correctly you can get rid of those by slowing down the pace a bit but without stopping. Otherwise just stop and get your breathing in rhythm with your cadence.

Try it, again if it is a side stitch this has helped me as recently as my last Oly race. Do a Google search on side stitches for more info; good luck!
