Fitter Radio Triathlon Podcast

We review the racing from IRONMAN 70.3 Rio de Janeiro, IRONMAN 70.3 Lapu-Lapu and the World Cup in Paraguay.
Plus, we delve into the challenges of racing in hot conditions and share strategies for heat preparation and acclimatisation. We highlight the importance of understanding individual responses to heat and the need for effective monitoring during training. We discuss the complexities of heat stress and acclimation for athletes and their own personal threshold for heat tolerance. We share the science around the effectiveness of active versus passive heat stress and the importance of hydration. The conversation highlights the different needs of male and female athletes regarding heat acclimation protocols and emphasizes the necessity of managing expectations during hot races. The group shares insights on how to prepare for extreme heat conditions, the role of heart rate in performance monitoring, and the significance of listening to the body's signals during competition.

We review the racing from IM703 Boise and WTCS London at the weekend.
Individual physiological adaptations to a repeated 8-wk endurance training period exhibit limited reproducibility. We discuss a recent study which demonstrates how an individual's response to one training period does not reliably reflect their capacity to adapt to the same training stimulus in the future.
