Ultramarathons are sometimes called eating competitions with a bit of running thrown in, and with so many different nutrition products and approaches at our disposal these days, it can be hard to know how to fuel properly. So, we talked to GU Energy Labs’ Nutrition and Performance Research Manager, Roxanne Vogel, about the ins & outs of eating on the run; how GU’s line of products fit into that equation; the importance of “flavor scientists;” and a whole lot more — including Roxanne’s lightning ascent of Mt. Everest and living in a hypoxia chamber.
