Hydration has always been one of the most important yet overlooked issues in races and especially in marathons. Our body produces sweat to lose the heat produced by our muscles during running, and it is important to make sure that the water loss is replenished to ensure our body is functioning properly. As a marathon exists in a compressed time period, our body’s heavy sweating rate makes it possible to get dehydrated quicker than usual. This causes our blood to grow thicker and the heart has to pump harder to push it around, which can cause several problems.
