Editor’s Note: Last month’s Physiology & Nutrition post, OSMO co-founder Stacy Sims’ regular column, discussed why she thinks gels are a poor choice for fueling endurance athletes. It’s a good read and generated a lot of comments and questions. It also piqued the interest of several brands known for their gels, one of which sent a rebuttal. As did one of the Peaks Coaching coaches, which serves as their column for this month. Both responses are posted below unedited, as was Sims’ post.
As an introduction and a little background, we’ve interviewed Sims when OSMO launched. We’ve also interviewed Allen Lim when he launched Skratch and asked similar questions. Then, in preparation for last year’s TSEpic, I interviewed Sims again about food choices. That post has a primer about why solids work when gels may not, which was one of the common questions in the comments. And Sims has already prepared Part 2 of “Why No Gels” which expands on that. Look for it this Friday. In the meantime, here are a few counterpoints to the original.

Understanding fueling strategies is essential to my long lasting success as an Olympic distance runner.

Having said this, I was disappointed to read the recently published article on “Why Not Gels?” in which the author misrepresented scientific facts and concluded that gels are “the most detrimental fuel sources for performance.”
