I'm a coach and one
I'm a coach and one of my athletes recommended it, then I listened to the Marathon Training Academy podcast that featured Emily Sisson and she recommended it. So I ordered the free sample pack. I first used it during a 21 mile run last weekend and here's my thoughts:
1) Easy to open which is a big deal when you're fueling on the run
2) Not too thick so I don't have to chase it with water
3) Flavor wasn't too strong which was fine for me
I plan to use this during my marathon.
