Tim Tollefson is a pro runner for Craft Sportswear, living in Mammoth Lakes, CA. He is also the Founder and Race Director of Mammoth Trail Fest. Tim is just eclipsing his tenth year as a trail runner where he's been one of the best athletes in the world. Approaching his 40th birthday, Tim is in a bit of a transition, still motivated to compete at the top while building the foundation for his next chapter. Tim is a longtime friend and our careers are unfolding in similar ways, making this a really fun conversation.
