Chrisanna, congrats! A first century is quite an accomplishment.
It sounds like it was a fun ride, too. Good sag stops help a lot on a long ride.

I just did a 175-miler this past Sunday, across Wisconsin, from Iowa to Lake Michigan in Racine. It was awesome! It's the longest I've ever biked in day. It was only supposed to be 150 miles, but turned out to be more. We had a support driver, but he got lost so we ended up going the last 50 miles with no support, no towns on the route to stop in, and even hoarding what water we had left, we were out before we hit town and could stop and re-fuel. Now I want to do a double century. It's funny, till you start doing long miles, it's difficult to imagine doing it. But once you get out there, you find out that it's possible. Quite a feeling, isn't it?

Anyway, one of the first things I did when we got done (went with 2 others) is mix one scoop of Endurox into my water bottle, shake it up well, and drink it. NOT my favorite stuff, but I have found that it really helps me feel better the next day after a long ride than if I don't use it. I don't use it after short rides, only the long, endurance type rides. I recover much better. I've also tried using the companion product to Endurox, Accelerade, for during the ride. If you can stomach the flavor, I believe it helps, too, to extend endurance. You can usually find it on sale from one of the big mail order bike places, and sometimes, your LBS will give you a good price if you mention the prices online or mail order.

Again, congrats!
