Dehydration is the leading cause of training injuries. It hinders every bodily function needed to run. A 2% decrease in body weight caused by dehydration affects your performance. Studies have shown athletes finish a 12K run up to 2.5 minutes faster when properly hydrated.
Water is 75% of your body. Hydrate to avoid injury, recover faster and perform better. Every physical reaction in your body depends on proper fluid levels, including:
Dehydration impacts mental toughness. Running is as much a mental challenge as it is a physical one. Even mild dehydration reduces concentration levels, negatively affects your mood and causes fatigue.
You can't forget to water a plant and then drown it in fluid to make up for it. The same is true for your body. Your body doesn't store water to use for later. You must hydrate continuously at the right levels all day to replace fluid loss.
So whether you carry, wear or hide your water in the bushes - make sure you are taking care of your body.
