Gu puts out a line that has caffeine, and one that doesn't, Cliff shot/blok also has an option for caffeine or no caffeine.
Now, it's my understanding that caffeine dehydrates. So I can understand that it would give you that little boost on a ride, but if it comes with the penalty of dehydration, is it really worth it?
How do people who really know what they are doing, choose which thing to use?
Are the people using the caffeine doing a time trial where they need to go 'balls to the wall' for 15 minutes, could use the caffeine because they don't need to worry about dehydration?
Or do people who ride distance use caffeine energy foods as well?
I ride 20-30 miles at a time regularly, and half centuries are very normal for me, along with a couple of century rides every year. Water is very important to me. given the choice, I can't possibly see using something that would dehydrate me. Am I way off here?
