With the unseasonably good weather this week, I do a deep dive into the science behind sweating and hydration and its effect on running performance.

In this episode you'll get tips on what to do to know if you are consuming enough fluid and electrolytes on your runs and how to manage this in long races too to avoid big slow downs and mitigate the chances and severity of cramps

Hydration is even more important when the temperatures tick up but as it's very individual too, it can bite you in lower temperatures too if you don't stay on top of it.
