Thanks for the advice.

I do have a jersey, but I thought being wet was good on a 100 degree day.

I need to use salt and get potassium tablets.
I need to research Isotonic drinks, gatorade or accelerade.

I have a couple of coupons for free sports drinks. I'll try them out. One thing I don't like to carry a lock (more weight) which causes me to avoid stores.

The idea of freezing your water bottles sounds good.
