What is the hottest weather you have run in?

Had a number of days (maybe a week in total) here in Houston when the high temp was 107. I ran at 2 in the afternoon during that time so maybe the temp at that time was only 105. I think the high temp of the day is around 5 or 6. It was not too comfortable and Houston is not a very dry city.

Hottest training runs have been in the 100-105F range here in Houston.

Hottest race i can think of was a 3200 in mid afternoon, 95-ish degrees or so. Fade badly at the end to finish in about 12:40 (slow i know) and a long way from my pr at the time (11:22).

I ran in 34C so about 93F once. I actually love the heat (at least what I consider to be heat) but it was really hard to run in, could just jog. Kinda sketchy too cause you could get heat stroke. At least in the cold it's just uncomfortable at times.

I don't know how people manage to train hard in the super hot areas.

It isn't necessarily the heat that makes running hard, but the Dew Point. If the dew point is high enough, your body literally can't sweat, and you begin to overheat.

One time when I lived in Louisville the temperature was only in the mid 90s, but the dew point was in the upper 80s. I've run in Phoenix many of time when it is over 100. That is uncomfortable, but bearable to run in. This Louisville run though, almost killed me.

I showed up at the park to run and only made it 3 miles at like 8:30 pace, I was in much better shape at the time probably averaging low 7's for an easy run. It felt like running in a steam room, just impossible.

The weather on the local news issued warnings all day about exercising outside because of the record dew point, but I thought I was tough enough to make it through it.

Agreed with what Batman said above. I've done runs in the 112 range in Phoenix and once the sun went behind the mountains it was actually quite comfortable. I thought that the temp had dropped dramatically but when I got back and checked my phone it was still 109!

I've done runs in Texas/Alabama/Tennessee that were 100-102 but had a heat index of 108 that were some of the worst runs you can imagine. I felt nauseous the whole time during one evening run of 3 miles.

I'm too old for that now. Treadmill it will be if it's that warm!

I still remember, it was July 2011 with the insane dew point in the Midwest. This article claims a heat index of 123 degrees in Iowa due to the dew point hit that week. Basically impossible to do physical activity. I ran on that day and will never forget how oppressive it was.

Summer 2007: I was only able to run at Chino Hills State Park from 11:30am-1pm before my shift started at 2. I ran 4-5 days per week in the low 100's everyday. Ended up doing pretty well with it, because a few weeks later, I ran the Disneyland Half Marathon on Labor Day, which was 107 at 6:30am! It was the hottest day of the year. My feet swelled in my shoes, and I ran barefoot from mile 6 to the end. My goal was 1:10, and I think I ran about 1:19 or so? There was a cut under my toe that didn't heal for about 6 weeks. Sucked.

I live in Tampa, ask me anything lol

I ran at night in Phoenix when it was like 104ish. Got back home without a drip of sweat on my brow and my shirt was completely dry. It was hot but not bad at all considering the sun was down. Hiked Camelback from the Cholla trailhead one afternoon in 104 heat as well. It was shaded and actually quite a pleasant hike.

Warmest: Six mile trail race @ 94 deg Fahrenheit with 85% humidity. Not pleasant.

Coldest felt worse though. Half marathon @ 3 deg Fahrenheit with 45 mph winds for a -25 to -35 deg. windchill.

Both races were in the same year of crazy weather.

45C which is about 114F.

I did not feel brilliant after.

I remember laying down on a stone floor feeling my heart beat. I wanted to jump in the pool but knew not to.

A three mile workout in 119 F (Las Vegas, not the official temperature, but unofficial reading on the time and temperature recording).

I used to live in Las Vegas. The hottest I have ever run in there was during the summer of 2013, 10 miles worth of loops at Baskin park in 118.
