Thanks! I have been experimenting during training, and found that the Gu gels make me gag, so those are out. The Clif Shots are okay, even if they do get a little sticky on hot days. For this ride, I will stick with the bloks and Nuun and then make a list of your other suggestions to try out for the next ride.

Actually, I just realized that the one thing I haven't tested out is pb&j sandwiches, which will be provided (I'm sure) at the rest stops. I'll be careful with those, don't want to suffer stomach cramps for 50 miles!
