    ABOUT THIS EPISODE

    In this episode, Matt answers 15 questions submitted through YouTube about race weight, weight loss and running performance.

    Topics include losing weight while maintaining training quality, carbohydrate cycling, calorie deficits during a marathon taper, post-workout fueling, finding your ideal race weight, losing fat versus muscle, GLP-1 medications and heart rate, creatine and water weight, and whether the same weight-loss approach can work for shorter-distance runners and triathletes.

    Matt also shares his own experience dropping from around 86kg to 69kg, how body weight played a role in eventually breaking 2:20 for the marathon, and how he is approaching the final two weeks before the Melbourne Marathon.

    Later in the episode, Matt gives an update on his Melbourne Marathon goal, testing the Puma Fast-R 3, the upcoming Dynafish launch in Australia, New Zealand and the UK, and his move to Lisbon for six months.
