My $0.02: I tried Gu Chomps recently. Didn't like them. Stuck to my teeth.

For background, my stomach is very finicky during a ride, especially when it's hot out. Most days, all I can tolerate is orange Gatorade, vanilla Gu and water. (Sometimes grapes are good, but I can't force myself to choke down most other real foods.)

This summer I've tried a few new things, including the Gu Chomps.

I also tried Gu Roctane, because I figured I probably needed to get more sodium during long hot rides. I don't love the flavor (vanilla/orange), but it's okay, and it doesn't upset my stomach. More important, it seems to really help. I've really been feeling much better during my rides, and I'm not retaining so much fluid anymore like I used to. So far I've been using about 1/2 Roctane, half regular Gu during rides.

I also tried Cliff Quench (orange) last week. It's a very low-sugar, low-cal electrolyte drink with a little organic cane juice for a touch of flavor. Unfortunately I hated the taste, and wound up tossing most of it.

So for me, Gu Roctane is the winner.

I'm perfectly happy getting some carbs with my electrolytes, since it's the only "food" I'm able to ingest during the ride.

BTW, Nancy Clark recommends 250-500 mg of sodium per hour during rides lasting more than 4 hours in hot weather.
