zip tie a few more plastic water bottles to your cage than usual and bring some hard candy to keep your mouth from getting dry..no one can train for the heat but you can prepare for it by staying in contact with your people, hydrating and bringing something to make shade..it's sometimes hard to come by ..run out of water and hang out without shade in 120 heat and the best athlete on earth won't last long.......also important is to keep telling yourself how much fun it is to be this miserable..tricky
