Gels, Chews, and Bars - Oh My!

This week's Pew to Half training run will have me doing 8 miles on Saturday morning.  It's time to start thinking about bringing energy supplements along with me on the run.  I haven't tried them before, so I am open to any recommendations.  If you've ever used any, please leave a Comment on what kinds of supplements you like best - including specific brands if you have any preferences.  If there are any that are just awful, you can let me know that too.  Thanks bunches!
