My Ultimate Direction Thunderbolt will be recruited for action tomorrow morning: My running partner Molly and I, along with Molly's 17-year-daughter, Lane, are headed outside the city to run. No water fountains or convenience stores to rely on for liquid refreshment. But we will be circling a big body of water: We're running around Hagg Lake to take in the course of the race we're doing in late September, Happy Girls Forest Grove half-marathon. I've got to see for myself how much of the course is on road versus trail and how many hills will rise to meet our feet along the 13.1 miles. A bunch of my gal-pals are doing the race, so I need to do recon for us. (If you live in greater Portland area--or even up toward Seattle or down toward Eugene--sign up for the race. The organizers put on a great race, and I love a great women's race.)

I'll be loving the Thunderbolt's three 10-ounce bottles with leak-proof caps, and I can count on the stretchy belt to stay comfortable and chafe-free around my hips the entire way around the lake. Even if Molly, Lane, and I get a bit lost...

Here are the three winners of an Ultimate Direction Thunderbolt, as well as their solutions for staying hydrated on a run:

Penny Verdeck: "I always plan my long run routes past peoples' houses that I know so I can stash water there--my run kinda looks like a flower on my Garmin map. "

Meg: "For my first marathon training (waaaay back in 2005), I did the drive-and-stash maneuver for long runs. I’m just about to start training for marathon #2, and I’ve been dreading the hydration issue. I now live in a more urban area, and there are a lot fewer safe hiding spots. I’ve been looping back to my front porch, but am also eager to get a belt, which would free me up to try more interesting routes."

Jerilee: "I really don’t hydrate during training runs- which is why I need to win this. Time to break that bad habit!"

Penny, Meg, and Jerilee: Please email us your full name, mailing address, and the size belt you need (XS-L, measurements shown on this page; we find they run a bit big so if you're in doubt, go with smaller size). The rest of you ladies: Stay cool and well hydrated, especially in regions hit by scorching temps.
