This week, Zoë and TJ are talking about one of the most misunderstood workouts in endurance training: the long run. From pacing and fueling to recovery and race-day readiness, they unpack the real science behind why long runs work—and what most runners get wrong about them.
They kick things off with a few Hot or Nots, breaking down three trending supplements in the endurance world: creatine (actually backed by science), nicotine pouches (just... no), and nitric oxide boosters (spoiler: eat your beets, skip the powder). Then, they dive into a listener question about post-ultra burnout, the fear of losing fitness, and how to rebuild motivation after a big race without overdoing it.
In the main segment, Zoë and TJ go full science-nerd on what’s happening inside your body during a long run—mitochondrial biogenesis, glycogen supercompensation, fat oxidation, and more. They talk pacing, fueling, hydration, terrain, and recovery, explaining how to get the most from your long runs without wrecking yourself.
Whether you’re chasing your first marathon finish or a 100-miler PR, this episode will help you train smarter, not harder.
