FF: What's the hottest race you've run in and how'd you get through it?
JW: The 2016 Olympic Trials in Los Angeles was probably the hottest marathon I’ve run, but I’ve run some track races that were hotter. You just have to adjust your pace. The longer the race is, the more your pace has to adjust to accommodate for the heat. Your body has to work really hard to keep cool, and once you start overheating it's really hard to reverse that. I think you can also be preventative in your fueling by starting the race hydrated and getting water early on.
When the weather is cool, I approach my fueling just from a calorie standpoint. When it's hot, my focus shifts away from calories to hydration because I know that’s what can break me. I just try to drink as much water as I can handle throughout the race. I’ll grab a cup every time I pass through an aid station, which is usually about every mile, and then grab my bottle at the elite stations every 5K. When I ran my first marathon in 2013, I wasn’t sure how to grab the water cups. My coach told me to come like an eagle out of the sky, squeeze the top of the cup and sip out of the end of it.
