Mary McCarthy isn't just a content creator who runs, she's putting down 60-mile weeks and running elite-level times without a professional setup.
In this episode, she explains why she runs her easy days genuinely slow, treats the first 30K of a marathon as a warm-up before racing the final 12, and why your Strava heart rate zones are probably lying to you.
She talks about fueling like her male training partners because under-eating is a direct route to injury, shares the brilliant story of overtaking her ex-boyfriend in the final 200 meters at Valencia without him even knowing, and addresses the criticism that comes with being a content creator running serious mileage.
Her message to the critics: you can't judge someone's training from the outside, the same way you wouldn't judge someone else's relationship.
