Perhaps you scientific types can back me up, but here's what I know about body temperature post-ride: The quicker you get cool, the better. You know, for recovery and such.
An ice bath is the quickest way, but it's more than a little uncomfortable. It's inconvenient, too, unless you have your own assistant. And if you have your own personal assistant, you suck.
Without the ice bath, you'll need something quicker and more convenient. I've been testing the
Aspen Cool Collar for the last week or so. It could well be that quicker and more convenient option.
At the initial inspection, it's nothing to get excited about. It's a tube of cloth with velcro on the ends. Inside are some small beads. I was fairly certain mine was underfilled at first. There just wasn't a lot going on inside there.
To "activate" the Cool Collar, you soak it in icy water for at least 30 minutes. The little beads swell and end up filling out the cloth tube pretty nicely. So, no, it's not underfilled.
But what does it feel like? Well, imagine putting a wet sock around your neck. It's like that at first. It's kind of strange. But it does help cool you down. I wore mine while I did my post-ride stretching. By the time it was drying out and warming up, I was ready to shower anyway.
After a few times around the block with the Cool Collar, I have a few things to note:
1. The online directions are different from those included in the packaging. Follow the online directions -- soak it longer.
2. The best way to get the collar really, really cold is by putting it in a big cup of ice water in the fridge, then going for your ride. It'll be ready when you get back.
3. The Cool Collar is not color-fast -- at least not on the first soak. The cup I used was filled with blackish water when I pulled the collar out. Keep that in mind if you have a white-collared jersey on. Subsequent soakings have yielded clear water. I have no idea what that means.
4. It takes a long time to dry. Lay it flat, on a towel, and wait. It's going to be a while.
Overall, it's a solid product. And it's pretty cheap, too -- $15. It would be easy to stuff the thing in a water bottle in a cooler and take it to a race. It would be especially useful for a two-race day. Works for me.
Pain, suffering, etc.: Went to the Bike Masters ride last night. It was predictably horrible. My HR average -- the average -- was above threshold. I was well above it most of the time. And I was off the back on the first big hill. It's to be expected, but that was painful. It'll get worse, I'm sure, before it gets better. Looking forward to it.
