Tim Tollefson returns to Trail Runner Nation for a wide-ranging conversation about what makes trail running special and what happens as the sport continues to grow. Using a "Wheel of Trail Running" format, the discussion lands on two big topics: cultivating the next generation of trail stewards and the ongoing professionalization of trail running. Tim shares how his work with Runners for Public Lands and Mammoth Trail Fest has changed the way he views trails, volunteerism, and the responsibility runners have to give back to the places they love. The conversation explores everything from carrying a small saw on training runs to the challenges and opportunities created by big sponsors, larger race organizations, and growing prize purses. Throughout the episode, Tim makes a compelling case that trail running's future depends on balancing growth with the community values that built the sport. It's an honest look at how runners can help preserve trail culture while welcoming more people into it.
