My only advice is to try and get your workouts in as early as you can.  I deal with a similar issue in St Louis from time to time.  Make sure you are properly hydrated and scale back your intensity a bit if you feel the humidity getting to you.  Though, during our recent heat wave I retreated to my treadmill in the basement because it was just too hot outside.

Hi PkPanther34,

I have been battling the summer heat and humidity here in South Florida too.  My strategy is to run early before the sun comes up, keep it slow, and keep it short.  I am just trying to keep my base ability there during the summer so that when the "cooler" weather comes in October, I don't have to start from scratch.

Learn to recognize the signs of heat sickness.....lightheaded feeling, nausea and chills, sudden stopping of sweat.  Been there done that...I grew up in Florida!

I would rather battle the heat than go to the "dreadmill".  Can't stand it!

pKPanther34. I live & train in South Fl. I have found that being properly fueled and running as early as possible is the only way around this brutal summer we are having. I did 22 miles Sunday morning. that was my longest run to date. I started running at 3:45 to get a jump on the heat and humidity. staying properly Hydrated and adding electrolytes makes all the difference in the world. It your body is not recently use to our type of humidity. I suggest you start out running short distances 60 to 90 seconds slower than your normal training pace. short walk breaks will also help. iuse several products by Hammer nutrition that have helped me. I suggest you check out their website among others that have plenty of good reading on running in high heat and humidity.

THE GOOD NEWs IS when you run in "normal" temperature you'll find your endurance and times are usually much better than you anticipated.

I'm a slower runner. My half marathon race pace is around 9:45. Training for my first Marathon in October my current training pace on long runs varies between 12:00 - 13:00 minutes depending on our current temperature and humidity. it's more about covering the distance this time of the year.

I also use the dread ill to do some of my speed work.

In the spring I run during the hottest time of the day till it gets over 85 then I start running early.

Another trick when it gets over 95 run one mile fast-  5k race pace- then stop rest three min. and start running normal speed.

Run 3-4 miles at 10k race pace. Don't run slow all summer.

Run out and backs. Its easer to finish fast if you are going towards the barn.
