This is interesting,
I was off with my boy to the supermarket to buy some jelly babies for tomorrows long run, but now we might just hit the baby food department. I think sports "nutrition" is a rather big con and haven't brought gels or bars for sometime.
Having just read Ben Goldacre's Bad Science, I've got a bit of a thing against nutritionists in general, suffice to say I've found no discernible performance difference from spending 2 quid on an energy bar or gel, or buying a cheepo Spar flapjack.
I still think the best stuff is homemade, whats to stop us just mashing up a banana and wraping it in something that it might stay in... hmmm... will have to consider my point a little...
