Scott Frey of Cerebral Performance joins the show for a deep dive into the next frontier of athletic performance. Scott believes the biggest breakthroughs of the coming decade won’t come from physiology alone, but from the brain and psychological sciences - and that belief anchors this conversation.

First up, Tim Tollefson returns to the show. In some ways, trail running is still having its “What Are We Even Doing?” moment. Through that lens, we take a look at the UTMB era, the rise of pro circuits, what the pros care about, and what happens when a grassroots sport takes bigger steps towards big-time structure. After that, I'm joined by Alyssa Clark for a roundup of trail running business news and ideation. Enjoy!

David Roche returns to the Singletrack Podcast fresh off his 12:18, second-place performance at the Javelina Jundred.

In addition to the race report, David dives into how high-carb fueling, recovery science, and fearless pacing are rewriting what’s possible in trail and ultrarunning, why overtraining and under-fueling are essentially the same thing, how athletes like Will Murray, Canyon Woodward, and Tara Dower are redefining performance ceilings, and what the next five years of the sport might look like.

Beyond the science, David opens up about aging in the sport, balancing family life with competition, and rediscovering joy in racing after the pressure of Western States. He shares lessons from his YouTube “Road to Western States” series, what he learned from stepping back, and how he and Megan Roche plan to rebuild their creative work heading into 2026.
