Lace ’em up and grab a handheld, because we are hitting the trails for a heavy-hitting (but light-hearted) Episode 104!

This week on Buckle Up: An Ultrarunning Conversation, Coach Brian and Mandy Mullen are sitting down with the resilient Aaron Nelson. If you’ve ever had a "DNF" (Did Not Finish) burning a hole in your soul or a "Why" that’s bigger than the miles ahead, this conversation is for you.

Aaron is heading back to the start line this May with a serious "redemption" mindset and a heart full of purpose. We’re diving into the grit it takes to return to a race that previously kicked your tail, and how running for a cause—specifically fundraising for cancer treatment—can turn your legs into literal machines.
