I jump in the pool before and after

I've started putting a sprinkler out and doing a one mile loop through my neighborhood.

LOL. Sometimes when running and it's getting warm, I'm grateful when I pass a home where their sprinklers near the sidewalk are on at that moment.

I run in the Louisiana swamp--high temps & near 100% humidity daily. I am currently running 50ish miles per week in anticipation of training for a 50-mile ultra in Nov. To tell the truth, I dread training in this weather over summer than the actual race (which will be in Nashville).

As others said, it's all about acclimating yourself to the conditions. At this point if someone was just starting I would probably advise them not too (it's really hot here and I think the adjustment curve would be too risky). However, a few tricks to the conditions I've been using: 1) Run EARLY--I'm out at 4am most mornings, 2) Run with FUEL--gels, water, electrolytes I use a CamelBak with a 1.5 liter bladder (which is good for about 10 miles before I need to refill it), 3) DIET--probably the most important factor, you have to eat right plain & simple, I'm plant based and I eat TONS of fruit, 4) Run with walking breaks, I've been doing this recently on my 20-mile runs (like a short walk every 5 or a short break when I refill at halfway) helps out a lot, 5) take advantage of the days that might be slightly cooler, it rained here last night so the temp was 72°F and felt slightly cooler than 81°F on Tuesday (still 100% humidity though) AND of course on the days that are hotter don't push it as your body has to work harder to maintain as it is.

Lastly, I document my fluid & food intake on all my runs/rides on Strava and here. I find it helpful to look back on for future planning. Especially when I'll be hitting 30+ miles for my long run come September.

I crazy hydrate the day before, take breaks under shade, and most importantly... slow down!

Trails. Get under some trees. It makes all the difference.

Since you have an irrational fear of running in the dark, I second this.

safety first, not irrational fear

Get some lights.

not fall to the ground safety, like getting mugged safety
unless you feel like running beside me and being my body guard

I run in Memphis at night and early morning. If I can feel safe running at night in a city with the highest crime rate in the nation then anyone can.

ETA: If you are that worried about it though, talk to one of the Miami running clubs or groups. I am sure you will probably find someone near you to meet up with that early in the morning.

Kudos to you!!! I will choose to play it safe and run in the daylight.

seriously, why would you encourage a woman to put herself in what she feels is an unsafe situation?

OP: if your a dog person get a 4 legged running buddy, mine watches my back for me

Tampa was incredibly hot today. 7am and it was already 82 degrees and close to 95% humidity depending on which service you believe. I immediately gave up on the thought of a tempo run, but did manage to get 6.5 miles in with only one short water break at around 29 minutes. i was surprised at my pace (around 7:47 for most of it) but I was absolutely suffering at the end but I did get through it and since I had the day off was able to get a bunch of things done so its been a good day.

Everyone has already said the right things..shade, stay hydrated, slow the pace and I would say absolutely wear the lightest clothing you have and avoid those darker colors. Also, get rid of the hats unless they are totally vented. I always shake my head when I see people running with baseball hats on. Crazy and dangerous. Guys, wearing those long basketball shorts close to your knees is not smart either. And ladies, you may want to rethink those black yoga pants that go below your knees. There is a time and a place and when it is over 80 degrees, you put that stuff in the closet.

Finally, and this was something I discovered today after 27+ years. My 12 oz Pegasus weighed 16.5 ounces at the end. Ouch. I didn't bother to see how much my soaked baelga's weighed either, but I am guessing that I was carrying 30% more weight on my feet at the end than the start. I am probably going to switch shoes mid run going forward and see if that helps.
