Thinking about ultramarathons? In this episode of the Marathon Handbook Podcast, Michael Doyle, Alex Cyr, and ultra coach Katelyn Tocci explain everything you need to know about making the leap from marathons to ultras. We define what an ultramarathon really is (1:40), debate whether the 50K is a “true” ultra (4:20), and share key differences between road and trail racing (7:00). We dig into fueling strategies (12:40), aid stations and gear (18:30), and how to pick your first ultra (30:45). Caitlin also reveals the biggest mistakes new ultra runners make (40:05). Then we dive deep into UTMB, Ultra-Trail du Mont-Blanc—its history (56:30), course details (1:03:00), controversies (1:19:00), and preview this year’s men’s and women’s fields (1:21:30). Finally, we make our podium picks and wrap up (1:36:00).
