I just came from where it was 120 in the shade (Kuwait), so 105 actually doesn't seem that bad now.

I think everyone else already covered it. If you're not out riding, you should be inside the clubhouse cooling off, drinking water (NOT soda), and eating at least some snacks (Gatorade isn't the best substitute for electrolyte replenishment, but it will do in a pinch). Skipping breakfast should not be an option - people who do would be just setting themselves up for failure.

Misters help, big fans for the shaded areas if they are available for when people are in the pits. Sean's idea of soaking his underarmor in cold water to wear during sessions is perfect. Even if it's just a regular cotton t-shirt is fine, it helps keep the core temperature down.

That being said, proper hydration is the most important aspect of it. And people often don't realize how physically intensive riding is. Stress to them that if they start to feel "off" in any way, to bring it in and take a break. Heat injuries are insidious, they sneak up on you and most people don't realize they're getting to that point until they are passing out.
