Last month I met up with my running club for a Saturday group run. It was going to be a hot day, really hot, but we were going early and mostly running on shaded trails. Eight miles later, my pace had cratered, I was soaked, having sweated through my shoes, and reduced to walking the last half mile to get back to my car. It was a tough and disheartening workout. But it didn’t have to be.
Just drink plenty of water and you’ll be fine. Right? Not exactly. Anyone that has run in the heat and ran face first into “the wall” can tell you that sometimes figuring out what enough means can be complicated. With summer training comes the heat and humidity, two of Mother Natures tougher foes for endurance athletes.
If you don’t have access to a coach or a lab, how do you figure out how best to hydrate so you don’t end up crawling along the sidewalk?
