You sure that wasn't your average speed?

111F in Kansas 2 years ago, but only for 7 miles. Felt like I was riding into a hair dryer. Drained my 96 oz camelbak.

This summer was like riding in hot oatmeal. I carried extra water in my pannier (frozen in water bottles) and took several breaks during the sections when there were no trees for shade. One afternoon, I went into a bathroom and soaked my jersey in water just to enjoy the cooling sensation of evaporation. It worked for about an hour but that was all I needed to get home.

I used to live in Tucson, and it was similar. I went almost 10 years car free.

I have ridden Tucson to Phoenix (142 miles) to visit my mom, once in the middle of August, so temps were above 100 F the entire trip, and if I remember, it was about 115F in PHX that weekend.

108F, a couple times. Have to make sure my water bottle is full (and preferably iced) before leaving work.

The commute is no big deal, since I can survive an hour riding in the heat. Longer rides (weekends and tours) make that kind of heat a big deal. That's when I look for a library (with air conditioning) or swimming pool.

Doohickie

About 105. I don't do that anymore.

I went out this last summer, headed out at 8 am to avoid the heat and decided to push my luck and keep going, got caught at my furthest distance form home about 20 miles out. By the time I made it back home it was about noon, bank clock temp said 105, I could hardly keep going bike acted like both tires were flat as rolling through sand. The asphalt was sticky and the tires were soft due to the heat. Last 2 miles was up and down some challenging (for me) grades. Hit the house, drank about 1 liter of water and took a tepid shower for about 1/2 hour then laid down exhausted.

Actual temp was above 110, full noonday sun midsummer. I skipped the next couple of days and went out at 6:30 to 7 am and after 7pm for the next few weeks to avoid the heat.

108
Drink lots of water.

This summer when it was 115 degrees. We took a reading of the pavement and it was 150. I only did it a few times. Even with 3 bottles of water, it was too much for me.

Same here since I live in Raleigh. It was miserable because of the high humidity and radiated heat from pavement. I wouldn't recommend it. I avoid commuting on days when forecasted high 100 F or higher. The trouble is that forecasts are often wrong, so I commuted on at least two days over 100 this past summer. I would rather commute on winter days with lows in the teens than summer days with highs above 100.

Well this is my first year commuting, so I have not rode in our summer yet. But after reading some of you other Phoenix valley dwellers have been keeping it up during summer....I guess I'll try. Honestly, not really looking forward to July and August out here. My ride is 12 miles and I leave work around 4PM, so it's the peak of the heat.

fietsbob

I rode the shuttle van to the VAMC , PDX, and back,
the driver had the heater going the whole way , Cranked Up.

AlmostGreenGuy

This is me about 2 minutes after an hour long ride home in 105 degrees and wicked humidity, a couple years ago. I kicked Abby out of her little swimming pool, and hogged the water for the next half hour. She still hasn't forgiven me. ;-)

The Chemist

Last summer I rode 145km on a day where the air temperature was about 35C (95F) with humidity making it feel at least 45C. I drank a huge amount of water and Gatorade that day, and I still might not have made it through except for the fact that it absolutely poured rain for the last 20km or so - I'd never been happier to ride in the rain, that's for sure.

lungimsam

105F, if I remember correctly. No problem. 5.7 miles one way only. Shorts and a t-shirt.
It was comfortable on the bike.
It was worse for the first 30 minutes at work with my body heated like a furnace and sweating for a while.
But not any worse than rides in the 80's and 90's.

We had record heat this summer, with more days in the 90's or above than ever before. I commuted numerous times this last summer in triple digits.

One day last June it was 106F plus humidity and I was feeling especially ornery, so I took the long way to work. Then at lunch I noticed there was no wind (an extreme rarity in South Dakota) so I decided I needed to take advantage of that situation while it lasted and rode 10 miles just for fun. Then on my way home from work I was feeling great so I decided to take the long way home as well. I wound up logging more than 42 miles that day.

Interesting living in our area, as we regularly see a 130+ degree swing from our yearly high temps to our yearly low temps. I ride in all of them.

truman

110 plus >40% humidity plus 15-20 mph headwind. Survived by being old and stubborn and hydrating all day. 102-108 and windy was pretty much the entire 2011 summer, and I slogged through it just fine.

silmarillion

There were a couple of days toward the end of July this summer where it was 100+ However you have to remember the thermal heat coming off the road is usually 10 to 15 degrees hotter.

I know on those days I was seeing the temps on my computer and HRM around 108.

I would rather ride in high heat any day rather than riding in sub-freezing temps...

devianb

101 degrees for 6 miles. I survived, but made a rule to never ride above 95 degrees.

Lurch

It was reportedly 103 degrees during the return half of my 14.4 mile round trip commute a couple of years ago. Had to repair a flat on the way back too.

norsky

105 was the hottest in mpls and minus 19 was the coldest.

erig007

I prefer exactly the opposite. South of Canada is too warm for me.

WickedOne513

I think mine was a trip home from work 16.3 miles in 103° luckily it wasn't as humid as normal here this summer. I just started freezing half a bottle of water and added a second bottle.

When I lived in Western Australia in the desert, we had a small cycling group and we'd ride on wednesday afternoon. Temperature was about 45 C (113 F). Also strong headwinds. The only way I survived was that a kind young lass in tight lycra shorts, obviously much fitter than I, suggested I tuck in behind her and stay as close as possible. It worked. I was able to keep up.

Notso_fastLane

I apply that rule down to about 35F, but I'm ok up to about 120F.
