Watch: Kara Goucher's Journey to 2016 Olympic Trials Marathon

I was introduced to the "The Dozen" in the winter of 2012 by my favorite Oregon running family. I love this set of core exercises for its efficient targeting of core muscle groups, and because no gym equipment is required! You can do this on a grass field, in your hotel room, or really anywhere you can lay on a flat surface.

This past August, we launched our Year of the Underbird program: an open application for aspiring Olympic Trials marathoners, with a promise to select 5 women for a 6 month contract encompassing a stipend, gear, storytelling, and community support. As we reach the end of our flight with our selected athletes, we invited each of them to share a few reflections on their past 6 months as teammates.

We are honored to support five exceptional Black women athletes challenging norms in the running industry: athletes, advocates, and powerful voices in the sport. We invited each of them to reflect on their journeys through sport: how their identity has affected their development, and how they hope to impact the rising generation of athletes. Hear from Madie Boreman, Kendra Coleman, Brenna Detra, Carmen Pelar Graves, and Ari Hendrix-Roach.
