are people aware of these little fellas? - http://www.maximuscle.com/viperboostbar/ - they're like rocket fuel. Have a couple of bites, wait about 30mins and off you go! (take about 2/3 hours to wear off, just in case you are planning on trying to get some shut eye!). Not only do they actually work, but they taste great and are soft and easy to eat. Great to get you home on a long ride when you would normally bonk.
