Careful, cause the same happened to me this weekend. The sweetest biker called me from behind to make sure I was ok. The pain had me walking half a mile. The heat can play a factor in the cramp as well.

You may need to put something solid in your tummy. I had a nice green apple. Also I carry Perrier with ice in waterbottle and Accelerade in my hydration pack.

Mineral water and an apple sets me straight. Sugar and doses of caffiene can probably throw you over heeving or in pain.
