  • 3 Deficiencies Holding You Back | Extra Mile
    Oct 8 2026

    Are you tired because life is busy… or could your body actually be missing something?


    In this episode of Untapped Extra Mile, Oli Patrick tackles some of the most common nutrient deficiencies - iron, vitamin D and B12 - and explains how they could be affecting your energy, health and running performance.


    Oli breaks down the warning signs to look out for, from unexplained fatigue and breathlessness to changes in performance, and explores when blood testing can actually be useful. He also explains why runners may need to pay particular attention to their nutrient levels, whether supplements are really necessary, and why simply taking more isn’t always the answer.

    Plus, we look at why deficiencies may be becoming more common - and the simple questions you should ask before reaching for another supplement.


    Because when it comes to performance, sometimes getting better isn’t about adding more. It’s about finding out what’s holding you back.

  • How To Run Like An Olympic Medallist | Daryll Neita
    Oct 5 2026

    What does it actually take to get faster? For Olympic sprinter Daryll Neita, the answer isn't running further, it's running better.


    Training five days a week in Florida, Daryll takes us inside the world of elite sprinting, from long winter sessions designed to build strength to the short, explosive work that creates speed. She also explains why sprinters rarely run more than 300–400m and why the gym can be just as important as the track.


    For everyday runners, Daryll shares the simple principles that matter most: stay injury-free, make strength work explosive, master your drills and keep chipping away.

  • Is Magnesium Worth It? What Every Runner Needs to Know
    Oct 1 2026

    If magnesium is so good for you, why doesn't everyone need it? Spencer Matthews and Oli Patrick get into one of the wellness world's most popular supplements and separate the genuine benefits from the hype.


    They look at what magnesium could mean for sleep, recovery and running, why your diet might matter more than your supplement cupboard, and whether different forms really make a difference.

    This episode is a closer look at whether magnesium is something every runner should be taking, or simply another supplement we’ve been told we need.
