"I think runners specifically are convinced that sh*tting your pants is normal...I see stuff all the time online of people saying, 'Oh, running causes me to have GI issues.' No, running plus your nutrition is the cause."

Grace Kelley really wants you to be able to run without sh*tting your pants. And she's got the myth-busting reels on Instagram to help! Kelley is a sports dietitian, part of the Lane 9 Directory, and a runner training for her first marathon, Fall 2025. Throughout the process, she's testing out a variety of gels so you don't have to, and keeping a spreadsheet with the facts. She's also making reel after reel of objectively bad nutrition advice from the internet, to save your gut and your run from an ill-informed fueling strategy.

We had a great time chatting with Grace about how she started running on Dry Land (IYKYK) after swimming through high school, how an appointment with a dietitian changed her career path and her own relationship with food, and more about her private practice.

Then we dig into some nutrition trends that may be affecting YOUR gut, and what might help.
