By the time I'm done with 6 ish hours on the bike and infinit, I want something different. I had a run mix for my first but dumped it 1/3 thru as it was making me sick. If it's hot I carry a hand bottle for water but live off the course.

If you have any protein in your mix, get rid of it for the run mix, it gets very frothy when it's shaken (unless something has changed in the last few years)
