Episode 91 - Can I predict my sweat losses without actually measuring them? | Prof. Ollie Jay

Imagine being able to predict what your sweat rate is going to be at any given running pace or power output, in different weather conditions, with reasonable accuracy. Well, now you can. In this episode Prof Ollie Jay (Thermal Ergonomic Laboratory, University of Sydney), one of the brains behind this new tool, joins us to discuss how it all came together, how accurate it is, and how to best use it. Have you gone to plan your fluid needs for training or race day, but weren’t sure how much sweat you’re going to lose? Do you train in a cool environment for an event in a hot environment? Or you just don’t have the time to measure sweat losses in multiple training sessions to understand your needs? This is the podcast for you.   Podcast Guest: Prof. Ollie Jay - Thermal Ergonomics Laboratory, University of Sydney.   Ollie's online presence: X: @ollie_jay13 LinkedIn: linkedin.com/in/ollie-jay-793a1b11/ Instagram: @thermalerglab   Sweat Rate calculator and papers mentioned: Sweat Rate Calculator: sweatratecalculator.com Validation - Indoor Exercise: https://doi.org/10.1152/japplphysiol.00829.2023 Validation - Outdoor Exercise: https://doi.org/10.1152/japplphysiol.00831.2023   Fueling Endurance eBook | T -12 Race Nutrition Course | Practitioner Resources The Fueling Endurance eBook contains answers to 49 of the most common nutrition questions that runners, cyclists and triathletes ask, and contains insights, tips, and quotes from experts and athletes.  The T -12 self-guided course will help prepare you for your next event, with online tools, guides, information and instructions to take you through the 12 weeks leading up to race day.
