Episode 129: The science of cognitive fatigue in running

Researcher and runner Katherine Boere joins Corinne to talk about the connection between physiological depletion and cognitive function in runners. We've all been there: Making wild choices late in races that we swear seemed to make sense at the time. Why do decisions seem to get harder after you've run farther? The two of them dig into: the research around cognitive fatigue in marathons and ultramarathons what role low energy availability plays and what it means for how you train, fuel, and recover Boere is a Ph.D. candidate in the neuroscience program at the University of Victoria and a senior performance researcher at the Nike Sport Research Lab. And much or her research is inspired by her own experience putting in the miles out on the trails.
