I don’t drink coffee.  It’s not a rule, I just don’t regularly drink it. I prefer to keep it as a back-up last resort.  I bring this up because these are my favorite running fuel: Chocolate Cherry Clif Shot Gel   I love them!  But there’s a slight problem…as delicious as they are, they are also “turbo”.  What does that mean you ask?  Well, it means that Clif puts enough caffeine in them to power a city!  It says it’s the equivalent of 2 shots of espresso.  Of course, non-coffee drinking me has no concept of what that really means, but I will get hyper on half a small dunkin donuts coffee. So, while this does give me a helpful boost during a long run, I can’t have more than one for fear my heart will explode.  Also, I’m not 100% sure that it was a good idea to down one before my run 2 hours ago.  I’m supposed to be heading to bed, but I feel more like heading out for a second workout! ACK! CAFFEINE!!!  😛
