Hey ladies! I am doing an olympic triathlon this weekend and aside from this eentsy beentsy problem, I am really excited!

Basically I have been running 8-10 times since my cross country bike ride finished in early august. At first, I found running to be really easy-- it took me no time at all to build up to the mileage for the tri. One day I ran 5 miles and I got a side stitch on my right side almost immediately, but I decided to power through it, running all 5 miles with that stitch. The next time I ran, I got the same stitch and decided to chill out. Then I managed to get sick for a week so I stopped running all together.

Today I got back on my feet again and got that same right side stitch. I don't know what the deal is! I don't think I'm doing anything differently than I was before. I try to breathe through it and relax the stitch, but I'm having difficulty doing that. I was well-hydrated and hadn't eaten recently

I am wondering if it could possibly be my shoes. I only ever had problems with side stitches before if I had eaten too recently. And these shoes are still really new to me. I didn't used to have problems with this when I ran on my Pearl Izumi Float II

Thoughts?
