Powerbar newsflash....it is basically a Fig Newton with protein and a few other tidbits. All you really need for inride fuel is a mix of fast and slow release sugar calories. Fig Newtons are about the best combo of that.....the sugary center and the flour cake. And they can be purchased in bulk at your local Sams Club for rock bottom prices. If you are looking for the ultimate last minute sugar rush, the best thing in the history of mankind is natural honey. It metabolizes faster than anything, and is the best thing in the world for a 30-45 min energy boost.
