In this episode Gerard Donnelly hosts triathlon nutrition expert Taryn Richardson to dissect popular nutrition myths and give evidence‑based guidance for triathletes. The conversation opens with a deep dive into the current creatine craze, exposing the prevalence of low‑quality gummies that often contain little or no creatine and emphasizing that creatine monohydrate powder remains the most reliable form. Taryn explains creatine’s physiological role (rapid ATP regeneration for short, high‑intensity efforts), who may benefit (masters athletes, peri‑/post‑menopausal women, strength‑training triathletes), and the risks of over‑dosing (saturation limits, gut upset, kidney load). She stresses individualized dosing based on muscle mass and medical clearance. The hosts then shift to race‑day nutrition, identifying the biggest mistake as failing to test and “gut‑train” a fueling plan under race‑intensity conditions. They discuss how stress hormones suppress digestion, the need to practice carbohydrate intake at the intended intensity, and how temperature and humidity alter sweat rate, sodium loss, and fluid needs. Practical tips include measuring personal sweat rates, adjusting for heat, and rehearsing nutrition in hot‑weather sessions. Carbohydrate loading is unpacked: it is not a single pre‑race pasta binge but a strategic super‑compensation protocol that builds on normal daily intake. Taryn warns against trying carb‑loading for the first time on race week and recommends practicing it during long training weekends to up‑regulate digestive enzymes and transporters. The episode challenges the “lighter = faster” mantra. Taryn argues that chronic calorie deficits harm bone health, hormones, and performance, especially for age‑group athletes. She advocates fueling for performance first; body composition will improve naturally when training is supported by adequate calories and protein. Habitual eating patterns, late‑night snacking, and the psychological toll of constant dieting are also examined. Finally, the duo reviews common supplements. Creatine and caffeine are deemed well‑researched but dose‑specific; protein powders, bars, and ready‑made meals are useful only as convenience tools when whole‑food protein needs are met. Multivitamin and vegetable‑powder supplements are dismissed as low‑value. Pickle juice for cramping is labeled a placebo‑only rescue, and beetroot juice is described as a modest nitrate boost that should follow solid nutrition fundamentals. Throughout, the hosts stress evidence‑based decision‑making, independent product testing, and the importance of having Plan B/C nutrition strategies for race‑day contingencies.
