Very good article on cramping from mxconditioning.com. Thank you. I think in my case it's a matter of "all of the above." Since my cramp onset is usually 4-5 hours into my activity (mountain biking, half ironman triathlon, enduro, etc...) then I surely need glycogen, which I take care of with a single cliff shot once per hour. Electrolytes, covered, I use Nuun in my camelback. I drink lots of fluid as well. Too much at times, since I end up peeing!

The stretching is a fascinating theory. I buy it for sure, it was my first inclination. My brother in law is a chiropractor and he encouraged me to get flexible for these events. I began a stretching routine back then. I'm still quite flexible today. I will now dedicate more time to stretching.

Thank you very much for posting those links skidad!
