15th in the World on a Sprained Ankle: Inside the 100K World Championships

Nine days before the 2026 IAU 100K World Championships, Allison Mercer sprained her ankle and wondered whether she would even reach the starting line. She ultimately ran, finishing 15th in the world and third in the masters competition.

Allison returns to Free Outside to take us inside the entire experience: the frantic ankle rehabilitation, racing 100 kilometers in extreme heat, her fueling and cooling strategy, Courtney Olsen’s late charge to the world title, Charlie Lawrence’s victory and the U.S. men capturing team gold by only 44 seconds. She also explains the sacrifices—and surprising out-of-pocket costs—required to represent Team USA.

Then we discuss Joe “Stringbean” McConaughy’s record-setting John Muir Trail run, their friendly FKT rivalries, ultrarunning’s latest OnlyFans controversy, and why road ultras might be the sport’s most underrated events.
