When I left work yesterday Wunderground showed temps from 115-120°F. The official temp for Phoenix was 118°F. Whatever. It was hot.

But it is a DRY HEAT

I like the heat. But keep in mind my rides are generally an hour, commuting in each direction, and then a few years ago when the office building was closed and working from home, I take my ride mid-day now. But I likes the heat, here is a 5-year dataset, with about 1500 points, looking at effect of temperature :


If you are thinking of riding consistently in very warm weather, then consider the Canada workplace heat index system as a guide. Canada, Mexico, and USA all have the same actual workplace comfort technical details, requiring three different (and very unique!) thermometers and some other analysis, but only Canada has done a masterful job of converting all that technical detail into something you can check on your mobile device and then decide what to do (in the workplace.. You just check temperature and humidity on your phone and then read a "humidex" number of the chart below, and then the decision about how often you can work and what other support you need (like resting in a cool room or drinking a certain amount of water) is prescribed. I propagate that Canadian system everywhere warm in my working world now, because everyone can understand it in a practical senses, despite they may or may not like the effect on the workplace.




Bravo Canada !

Sure is.

That thing might spontaneously combust! Was about 80f here today with medium humidity, got in a good 60 miles.

Stay safe...

I‘ve been using a geigerrig which has the benefit of air pressure to pump out the water. You can then spray your head, neck or whatever to cool down. There is one downside I’ve learned. A few liters of water on your back is heavy. I’ve discovered I need to adjust my bike’s handlebar height to prevent the pain.

But it is the easiest way to get enough water.

There is one thing that scares me more than sustained triple digit heat; it is the electric bill from running the AC that goes with it.

So after your 100*+ rides, how do you cool off?

I crank down the AC at night then when the electric bill hits ... But I sleep good...

Summers might be costly, but our winters are cheap.

I prefer 50'F to 80'F, so recent 90'F+ with high humidity in the UK has been challenging, but my rides are never more than two hours long.

Many years ago, I ended up in a ditch in France due to heatstroke, lessons learnt etc.

100-102 all this week with the humidity heat index 110. Tired of the heat.

I may be a wuss but after heart surgery and resultant meds you'd need one of those special Fed guys from Seattle to get me out the door much less on a bike.

I just take a shower, have something to eat and drink lots of water.

I always have gel packs in the freezer and fridge. As soon as I get inside I put a cold pack on my neck, grab another for my legs, get a quart of something cold to drink, sit down and try to avoid being covered in warm cats. My oldest cat is lap leech.

Humans around here are just lumbering around all slow and lethargic. The 100+ doldrums. Walking zombies at HEB the regional grocery chain.

So, a normal day then?

109° this coming Sunday, Monday, and Tuesday in the Antelope Valley, (high desert in northern Los Angeles county). Be safe everyone riding there.

105F today. Couldn't keep my heart rate down, even pedaling at a minimal effort. Just took it easy and drank more than usual. Wasn't fun, but it makes days in the 90s seem cool in comparison.

Going to Junction, Texas tomorrow to sit in the South Llano River it is forecast to be 106 but I’m not going to feel it. Not going to stop in Covidville on the way. The name of the town is being withheld to protect the guilty.

Swimming pool and cold drink.

107 degrees at 3pm here in DFW, Texas. That's why my weekday rides are starting at 4:45am when it's a nice, brisk 85 degrees...

I almost always end up in the pool after a ride. It's been freakin' toasty around here lately (110+ almost every day for weeks) so I do all of my riding early in the mornings or on Zwift.

Was in the river for 7 hours didn’t feel the 106 degrees. I drank ice cold Gatorade Zero all day now I got a sore throat! Too much cold liquid and this is what happens. Been soaking up the AC inside but I can’t stand it inside. I’m waiting for that cool 99 degrees then I will water the plants and be outside. It would be something to actually have a definitive Summer, Fall, Winter and Spring.

Where did everyone go?

A couple of weeks ago I decided to see how much fluid I'd lose over the course of an average ride in these higher temperatures. The temp was hovering around 100 when I left and I ended up losing a full 6 lbs in 2 hours/42 miles (I'm 6'4 215 lbs)
Since 1 liter of water weighs 1 kg, 6 lbs comes out to 2.72 liters of water. Add the 1 liter of water I drank along the way and I lost just under 1 U.S. gallon of fluids in two hours.....

Needless to say, I gained the weight back pretty quickly
