  • Shoe controversy, Boston marathon training & Thyroid hormone use in Olympians

    Shoe controversy, Boston marathon training & Thyroid hormone use in Olympians
    Sep 12 2025

    We start off with a listener question about recovery runs before diving into the Hayden Wilde shoe saga and a mess at the Tokyo World Championships track & field with the warm up track. We then discuss whether the women’s & men’s races being on the same day for Paris Roubaix is going to be good for the women or not before briefly previewing the Ironman World Championships. We finish with two research papers, one on use (or overuse) of thyroid hormones in Olympians and one on the training characteristics of Boston Marathon runners.
