I'm trying to lose some weight so I try to keep the calories as low as possible on my rides. For the first hour you probably only need water - 2 bottles. I like one water and one Gatoraid though. Anything much longer than an hour you will need to re-fuel. But don't overdo it. Remember, you probably only burn about 500-600 calories an hour (this varies of course) so you don't want to take in too much. Just eat a few bites of something every 15 minutes and stay hydrated.

Copperas Cove? I'm just up the road from you. We ought to get together and ride!
