Season 4 Kickoff: Courtney and David Sinclair Both Named #10 on the 2025 UROY List?

Season 4 of The Next Aid Station is officially underway.

We kick things off by diving into the current state of ultra running, breaking down the top 10 men’s and women’s ultra runners shaping the sport right now. From dominant veterans to athletes redefining what’s possible, we talk performances, trends, and what’s standing out heading into the season.

We also preview what’s ahead in Season 4—new conversations, deeper storytelling, and a continued focus on the people, races, and moments that make ultra running what it is.

Whether you’re lining up for your first ultra or deep in the sport, Season 4 starts here.
