Forums >General Running>Does this make me a hothead?
OK, so I'm a data geek.....
Went for a short easy run today - 95 F and 80 F dew point. It's at least two years since I have seen those temperatures. Body temperature went from 97.5 at the start to 99.0 at the finish. I was going to take the day off, but could not let the heat and humidity go to waste.
Did a tempo run last week at 92 F and 74 F dew point. Five miles total with the last three tempo. Lost 4.5 lbs and body temperature went from 97.6 up to 100.0 at the end.
In both cases, I was comfortably sweating enough to be dripping wet at the end. I think it would be bad idea to do attempt a long run at these temperatures.
If you're not bringing water (or otherwise don't have access to it), then probably yes, but as long as you have water available and adjust your pace accordingly, I think hot temperatures shouldn't in general be a reason to avoid longer runs. That being said, personally I both dislike running in high heat and don't like having to drag water with me, so I just run early enough to avoid the worst of it.
Based on the rapid weight loss and temp increases you describe I think you need to pay more attention to hydration (both before and during). Just my 2 cents.
My pace vs heart rate and perceived effort is roughly constant until I sweat off 6 to 7 lbs. After another 1.5 lbs sweat loss, my heart rate will increase 30 BPM. I last did that about three years ago. It was not fun - tempo run effort and heart rate at a slow recovery pace.
I've put together a chart of sweat loss vs distance and temperature. I use that to decide if and how much water to bring.
Imminent Catastrophe
Been there. At some point I pass a threshold and my HR goes way up. At some point the heat/humidity exceeds your body's ability to dissipate it, even if you have adequate hydration. Then it's time to cut it short or find some other way to cool off your body.

If you want accurate readings, you should use a rectal thermometer. Just saying.
I ran a 50k that started at midnight. It was 96 at the start (and humid). 88 at the finish.
I did not spontaneously combust.

That would be a way cooler story if you did.
It was hot. Great job. Saw your time and lap consistency in your log, too.

Ah, but.
My goal was 4:59:59.
Missed it by exactly 30 seconds. (official time 5:00:29).
Fooey.
Still though, I was 10 minutes faster than last year and the weather was about the same. A fun time.
Yes, but I could not tell it.

You can + the thread at the top.

Wouldnt that be the greatest part? Telling a story after your combustion that is...

Personally, I find its not just hydration that's important, but actually eating a good amount of salt the couple of days before your long run so you can actually retain the water and stay hydrated. (Btw that logic could be totally wrong). Its just Ive run 10 miles in 85 F and lost 5lbs (im normally 145) and not had to much salt prior, but today i ran 12 miles in 90- 85 F and lost a pound and last two nights ive had a fairly salty diet.
