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.
