Need tips on running in the heat

Run slower
Drink plenty of water pre run
Bring water with you on the run.

Invest in a camel pack. You need to hydrate before, during and after your run. If you live in an area where it is hot (like I do) then you need to stay hydrated big time.

Drink lots of water and a little Gatorade. Eat lots of veggies and fruits to help you keep hydrated.

Wear super light clothing. I have thin cotton t-shirts that I like to run in.

And try to keep to the shade. I live near a park with lots of trails that run through the woods. I wouldn't run half as long if I didn't have the tree coverage!

I don't run a lot, but I do it in triple-digit weather -- and I walk for hours in that heat on a regular basis. Aside from conditioning myself to be out in it, here's what helps me.

1. Hydrate, hydrate, hydrate. Before and during. This can't be emphasized enough. I drink a quart before going out, carry a cold quart with me, and duck in to buy another when I've emptied it. Yes, this means taking a bathroom break. It also means forcing yourself to come in for a little while, and that helps. Some people drink Gatorade or some other electrolyte-y thing to replenish the minerals they sweat off. I find a bottle of Perrier works quite well. YMMV.
2. Don't wear antiperspirant. Let the sweat flow, except into your eyes of course.
3. Your hair looks longish like mine. Shower right before running. Then put your hair up (e.g., in a bun or a clip) while it's wet.
4. Wearing a hat is a mixed bag - it keeps direct sun off, but holds in the heat you generate. YMMV. Sometimes I find one helpful for shorter jaunts.
5. Clothes, either strip down to the essentials (sports bra and close-fitting shorts) or make sure what you wear is light-colored and reflective, but not heavy. Surprisingly, natural fibers can hold the heat in more than today's synthetics.
6. Seek the shade. Run on the side of the street that has shade from trees or buildings. Also sprinklers and water fountains.
7. You might try a cool scarf. They take advance preparation, but the effect is pretty nice for a couple hours. Search Amazon for the phrase. Sometimes you can get one for as little as a buck at the local big-box store.
8. Take breaks when you need them, and don't be an idiot. If your heart is racing and your face is beet-red and you're feeling dizzy, STOP. Sit down or bend over, whatever it takes to get your head lower than your torso. Breathe deeply. If you can get somewhere cooler, do.

That's about it off the top of my head. I'm sure some runners will chime in with helpful advice. This is more "desert rat/coping with the heat" advice. Good luck!

One more suggestion -- Don't sprint and then jog. Instead, finish strong: Jog until you're close to packing it in, and then get in your faster running, especially when there's an air-conditioned destination. For me, this makes the difference between finishing the run and having to quit.
