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!
