still searching for the perfect fuel

[maillotpois]

I agree, but prefer a different Hammer product -- Sustained Energy. Same stuff as Perpetuem, but unsweetened/unflavored, so I can mix it with my favorite flavors of Gu2O powdered drink. The protein combined with carbs keeps the calories coming in without the spike that just gels would do.

Ditto. I like to mix 2 scoops of SE with 2 scoops of an electrolyte drink (generally Power Bar performance). Then I augment with real food (specifically V8s, PB sandwiches, bananas, PAYDAYS, Wheat Thins) or Hammer gel as needed.
