So I popped outside to get a slice of pizza to supplement my peanut butter and home made waffles for lunch. Figured the extra sodium is going to be pretty critical going into tonight's TT effort.
Gonna be warm. Someone shared this article. Makes me feel a bit better about it. That said two weeks ago was pretty tough, at the end of the ride we were all pretty damn warm, last week not so bad.
The heat, it is all in your head.
Assuming you don't dehydrate too far or get heat stroke. Which oddly are usually coupled together. The body cooling system works really well on the bike as long as you are moving and are hydrated enough. Once you drop below the critical hydration level body says "fuck, i can't spare any more water - we're in trouble - no more sweat" well yeah you're gonna do some major damage. hydration isn't just during though. Right? Yall know that.
It is all about the previous 24hrs. Not just water but sodium intake in that time too. Excessive sodium chloride will boost your ability to hold water and since you sweat both... hey that's how it works.
WUGAZI has been pretty f'n awesome. Cranking this stuff.
Soundtrack for the day - at least after the Tour finished (I have a lot of cleaning to do at the desk, i'll actually get started on it tomorrow maybe). Oh language warning. (what would expect from a mix of Wu-Tang Clan and Fugazi). Props to one of the nicest guys out there Jeff carrying the SLAMMABAMMA HAMMAH Bramhall for the link and suggestion.
grab a quick read of this... about food
And then there is this on Google+
That alone makes Google+ the antithesis of Facebook. Facebook has been taken over by brands, companies. Sure why not you have a huge massive captive audience. 'Your' "advertising" is even more effective there than on TV. Some people are joking that all anyone does on G+ is talk about how awesome G+ is. Have to say, I disagree, that is what FB is for!
Track 10 is on repeat... and LOUD

"Heat is in your head" article is BS. What kind of cyclist averages 160-180W? That is recovery pace for most of us. So I supsect they were not trained cyclists.
When I participated in a heat study at UNH, I could not see any temperature displays. I just knew the room was hot on my hot trials (95F, very low humidity, two industrial fans blowing on me). No body core temp either. Only the researchers could see that. In a hot trial, it took only 20 minutes for my body temp to reach 103.5F, which was the safetly limit where they cut me off. My power output plummetted too. Above 104F, permanent organ damage, coma and death can occur. I was the only subject unable to complete a hot trial (tried twice). At room temp, I was the fastest subject in the study of trained cyclists. Forget average power, but it was over 300W for about 40 minutes.
Perhaps there is a psychological aspect, but I think in a competitive situation, a trained athlete can pretty well block that out. It becomes a matter of the body shutting down when a critical threshold is reached.
I have a hillclimb race on Saturday. Temp is expected to reach the 90's again. Average speed is about 8mph, so not much cooling. I know my core body temp will reach 103.5 well before the summit and things will start shutting down. I'll lose no more than about 2 lbs of fluids in that time, so I will still be hydrated. Our bodies have self preservation mechanisms built in to prevent our minds from driving body temp much above 104F. A hot day on a hill is more of a test of cycling economy and cooling efficiency than fitness.
Good Comments Doug. I'll take a high speed TT over a slower CX or MTB ride (or hill climb) in the heat any day.
Back when it first got really hot Matt Kraus posted a comment about how important it is to train in the heat so you can adapt to it and get your body's cooling systems used to it.
Hopefully I'll be doing the max effort for less than 20 minutes... hopefully.
It really isn't something I should be joking around about, heat is pretty serious stuff.
The heat advisory and warnings shouldn't be taken lightly. Esp if you haven't been outside much.
(I was getting carried away a bit).
That said I did put two "servings" of salt on my peanut butter (unsalted) and waffle at 3:30... and am looking for a 3rd water bottle to be used 1° for cooling post TT
Now I'm questioning commuting tommorow. Since I started losing weight / biking my tolerance to heat is better than ever - but sheesh! Permanent organ damage?
No different really than ultra distance runners who suffer permanent joint damage after a grueling hundred miler. Athletes have a knack for pushing past the first warning limiters. Heat is just one of the barriers that entail considerable risk if you try to bully through it.
riding in the heat isn't a big deal unless you're going really really long or really really hard.
stay hydrated, and take it easy...
the bike is great, as long as you are sweating and have some skin exposed (legs arm and face are often enough) and have a breeze you'll still cool down even in 100 degree weather, and you can always just slow down, take a break.
Hot days are good to practice the commute trying for the lowest HR avg possible (unless you have a long commute then you'd be going for the longest one often).
Was really okay today. I packed a bit of ice around a couple water bottles in an insulated lunch box. We all cooled down with it post TT.
Worked out pretty damn well.
