    Disclaimer: I am not a professional!

    With that being said, I am currently in a very hot environment that is only going to get hotter throughout june and july.

    So far, I've been running in 102 to 108 degree weather.

    I stay hydrated and I flee from caffein and other dehydrating substances.

    I haven't died yet, luckily.

    So I'm sure you can pull of 90.

    We used to do up to 18 miles in very hot weather, and a lot farther on roller skis (50+ km). Look for shade, carry water and drink it every 20 minutes: I used to carry two water bottles: make sure you re-fill them when you can.

    An electrolyte replacement in the water can be good, but thin it more than the instructions say. The main thing is still WATER.

    Wear a shirt, maybe a hat.

    If you feel AT ALL faint or weak, STOP!

    Other than that... We used to book up to 20 hrs a week in very hot weather, with no damage at all.

    I think it's personal preference. I like to run when it's hot. If the weather is cold, I usually tense up and it affects my running form. Even if I'm wearing warm running clothes.

    It's sorta dumb, but make sure you keep hydrated at all times and rest every so often. Also make sure you have on sunscreen.

    Run in the heat...but be smart about it. Run in the morning or later in the evening to avoid the hottest part of the day. Hydrate well (and often). Find courses with shade (trails can be great, but so are tree-lined streets if they are an option). The more you do it, the more you will build your tolerance, so ease into it...increasing your mileage in the heat over time.

    I did that once without proper hydration. But it was about 95~100 degrees. I ended up with a heat stroke.

    So I guess.....don't do it?

    I just did 5 miles today here in Chicago. It was in the upper 90s. No problem! I always do it. No water bottles either, just water fountains around.

    If i were you, i'd run early in the morning or late evening when the sun is down,
    Hydrate as always and you can get away with running shirtless during those times

    It's fine. When I run in heat, I just make sure that I'm hydrating (1/2 litre per hour but you need to know your own number - too much will cause bloat) and I take electrolyte replacement salts (1 every 30 min).

    Don't take both salts AND something like gatorade - do one or the other as your salt protocol.

    If you're running for less than an hour, don't worry about any of this. If you're doing multi-hours, then it starts to matter.

    LOL! Sorry dude, didn't mean too. Maybe we in Chicago have become immune to the weather. I mean, even in harsh 10 below winters I don't wear gloves. I dont get cold... my hands will start getting little cuts and bleed, but, eh, I moisturize them and move on.

    Dude I do it all the time....last summer it was over 100 and I ran...Suggestions...Eat a little something an hour before running like yogurt, a couple of bananas...carbs and or protein for energy...stay hydrated..carry some water with ya if need be...lack of water zaps your strength...Lastly...pace yourself...your not running for the speed as much as your running for the cardio....Happy trails....BUD

    Is no one here from Florida? Go by the heat index! Aka the weather channels "Feels like ____" temperatures. Otherwise temperatures can be misleading IMHO.

    If you aren't used to running in 90F, don't do it, especially if it is really humid and full sunshine. It takes a while of being used to running in the weather to get used to it, at least a week or two. Whenever summer hits in Florida, I always pace myself because heat strokes are so freaking common in the sunshine state.

    In regards to those talking about running in 90/100/110 or whatever degree weather, I really think they should clarify on what exactly the conditions were. 95F in swamp-ass-BFE, FL is no where near the same as wonderfully dry 95F in the Palm Desert, CA.

    If it is 95 degrees outside in Florida with like 80% humidty in full sunshine.. that is like a heat index of 151.

    Here's a good link from about.com ... I kind of think it is funny that heat index is under FL information. http://goflorida.about.com/od/floridaweather/ss/weather_3.htm

    90 degrees? that's nothing (i'm used to triple digits). just stay hydrated, wear sunscreen, and remember to go shirtless and send us pics.

    Do not do that. You can fold in heat other ways that aren't as ... deadly. I love to work out in a warm place with sweats on, but it's easier to pace and keep track of my heart rate that way. With running, it's so easy to push over and not realize and if you're hot, it could end badly. Run under cooler conditions, but wear sweats, you'll see that the body can make it's own heat.

    When you run in the heat, you have to understand the increased physiological demands. Your exercise means your muscles need blood, but you are overheating and your muscles create heat, so therefore, the skin will get priority. There is a conflict of interest of your body's needs: getting rid of heat and moving. The brain can only open the diameter of so many blood vessels at a time, and you only have so much blood to go around. The skin blood vessels will dilate and the muscle blood vessels will constrict more than they would if you were not in heat (not like that, physical heat...heh). You will lose water in attempt to evaporate it (the evaporation causes the heat loss, not the water loss from your pores...so if it's humid, less will evaporate, and it's even MORE dangerous--you could get a fever quickly).

    In primitive times I'm sure you ran away from the bear until you fell over from heat stroke. In today's times it's just not going to be a very good workout: you cannot work as hard because of the heat, you will lose more water and electrolytes. This is what a gym is for...or wait till sunset or do it early before it gets hot.

    This is well-established enough that it is in undergraduate exercise physiology textbooks, so any kinesiology major should be able to verify.
