111 degrees here in dusty old El Paso a few years ago. Most of the summer is over 100 in the daytime. We keep Camelbak in business here in the Southwest - Hydrate, hydrate, hydrate, sunscreen, sunscreen, sunscreen, hydrate some more, and you get used to it.

The only race I ever podiumed on was a six hour mountain bike race I entered a few years ago. It was 104 when we started at 4 in the afternoon. The night laps were a break from the heat, but I was too tired by then to notice.

107 later today, but only 10% humidity. It's not a "fun" ride, but very do-able if you hydrate constantly. Supposed to get to 108 tomorrow and 13% humidity. It's kind of weird arriving home with a dry jersey, but caked with a salty coating.

Yeah, it's the humidity. THAT is why I will never live east of the Rocky Mountains. The humidity would kill me. At least you can do stuff in the dry desert heat.

I got out and rode in the 109 degree heat. It was my first day back in the saddle after an almost two year layoff. I had been trying to get out all that week and something kept getting in the way. I finally got my afternoon cleared up on the day of the record heat, and I wasn't about to let it keep me from finally getting back on the bike. Just coasting I could feel the heat beating against my chest. It has felt pretty decent since then, only being around the low 100s to upper 90s.

I commute to and from work in NW Florida. Most summer days the cycle to work isn't too bad (low 80s usually, but humidity is usually also at about 80% which is bloody obnoxious), but the cycle back during rush hour at 4:00PM is pretty atrocious. We had a couple weeks where our daytime temps weren't lower than 98F and hit up in the area of 100-102F a couple times. Throw in a 60% average humidity in the afternoons and it makes for a very sticky ride to and from.

I was out every day hiking/walking/trying to run at the Warner Parks during the heat wave last week. I also had the place to myself, as I'd go right around noon, when the moms with strollers and the senior citizens had packed it in due to the heat. I sweated like crazy but never felt anything like heat exhaustion. I went in the late afternoon when it was well over 100 degrees and vowed to go MUCH earlier the next day.

For me it was probably around 110F. Last year we had 90 days over 100 and checking my log from last year I road on at least 50 of those days. The key is to hydrate, use sunscreen, and realize when your body is telling you to stop and get out of the heat.

Last summer on a commute home it was 110°. Last Friday it was 105°.

Not a lot of fun.

113 in Oklahoma City a couple of weeks ago. Tied the record for the hottest temperature ever recorded. It felt like it was about 140 in my shoes!

113

Two 24oz water bottles lasted 15 miles and I was done. Screw that, not even remotely fun.

For a Texan I have fairly low heat tolerance, but when it comes to riding if you're not afraid to let sweat build up it can be nice, the breeze evaporating the sweat and cooling you off. I'd rather bike than walk in heat. I think it got into the 115-ish range my first ride a couple of days ago. I agree with another Texan I saw in the thread; I'd rather ride hot than cold. You ride, you sweat. Sweat will evaporate and cool you, no matter the temperature. When I was a kid I'd refuse to ride in the cold because I hated the feeling of my nose going numb. Guess that's the difference in growing up North and growing up South. Went to Tenessee one summer for church camp, and the greeters appologized for eighty degrees. We all agreed that was ridiculous, it felt great.
