Ok this will be the first hot race. You people better hydrate with water..... yes there are a few who need that part of the statement. Spectators that means you too. Also please carry extra water and some wet rags for the racers.
Racers if you feel you are getting overheated do not stop in the woods find someone then stop. You will not be able to get any air in the trees. Don't be shy if you need help ask anyone.

Mix 1/4 Pedialite with water in your hydro pack. I fill a water bottle 1/2 full of Pedialite (you can get flavored or non up to you) freeze it then place the frozen block in my hydropack. It will melt and keep the water somewhat cool not cold, but in hot weather you don't want to drink cold water. The best way to hydrate is to drink cool or warm water. DONT OVER PEDIALITE you can over do it and it will be counter reactive.
