What this translates to, to ME is......the importance (or, benefit) of keeping your hydration as cool as possible, for as long as possible.

I read Lim's article. Keeping the core temp down seems to be important.  I wonder if this is even debatable?  How much better do you perform in 60deg. weather v. 95deg. weather?



Just saw a short topic in Runners World (might have been an older one from last year--it was in a stack of magazines someplace I was waiting last week) that quoted some research that said that for every 5 degrees over 60 degrees it is during a marathon race, the average pace of each runner drops by 20 to 30 seconds. That's a HUGE amount.

Now I just saw this last week and I have not yet had a chance to research the article that they quoted from but I intend to very soon. I know that I run slower when it is very hot out, but that seems like a huge amount to me.

I agree, but I can't help but wonder about triathletes that have issues shedding heat (I'm one of them, of course it's hard to shed heat when it's blazing hot all the time down here). 

Torbjorn Sindballe always talked about his frustration of not being able to win Kona due to his ability to keep his core cooler.  He used all sorts of tricks including gloves that held ice to keep his core temps down.  Macca has also discussed his work on reducing heat.

So it does beg the serious question if this is this a valid way to help keep core temps down during the run in IM races.

This makes a good case for those 'stay cold' water bottles.

Here's an interesting page that I found while searching this topic on the internet. Just an overview with a further link to some articles, but interesting reading:

Way to crush my dreams of an electric-powered mobile slushie cart at the NYC marathon.  You runner folks don't carry enough cash anyway.  Pfft!

Don't worry, one of the cycle companies will start producing a hitch you can attach to your bike so you can tow one along the course with you.


I will take one in carbon...thank you.  Sealed

There are ice vests that would be far more useful to running than drinking slushies.

As previously mentioned, the general science here is not at all earth-shattering. Keep cool however best you can. But slushies require far more...infrastructure than other things. And they certainly aren't going to have Icee machines on any courses.

They had a snow cone machine on the Eagleman run course this year.

Gee, shock that the triathlon community would embrace this sort of thing.

Slushies give me brain freeze...would be painful to run like that Surprised

kellekl - 2010-08-03 11:07 AM I just got a snowcone maker for my b-day. Slushies at my house before the next group run! -k


The health and sports magazines are all over this, I've read it in about 4 places so far, and one of the suggestions is just this ^^^, make a gatorade snocone.

FWIW - gatorade freezes colder than 32F, a little experimenting with time in and out of the freezer and you should be able to get a slushie consistency.  Gatorade doesn't expand as much as water when frozen either.

What is the weight penalty to cooling effect ratio of an ice vest?  Carrying all that extra weight?

But only 1 degree lower at 31 degrees F.

Also considering Gatorade is 96% water the difference in expansion (if any) is negligible.

So I would not consider these to be big factors.  They would taste good however

I couldn't say, I've never worn one. None of these are going to be "perfect" solutions, anyway. It's all attempts to allow you to maintain a higher effort for longer.

I think you mean that it freezes at a colder temp than 32. Ice will freeze colder than 32 as well, 32 is just the temp at which it starts freezing.

And again, your body won't absorb it until it warms it up. So, not only are you expending energy to exercise, you are expending energy to warm the gatorade/slushy/whatever, and you are not getting your expected absorption rate either. Might be ok for long rides, wouldn't want to try it in a race, especially a sprint/Oly.
