When the temperature is higher the right hydration is far important. Even when drinking properly, it's normal to end up a bit dehydrated at the end of a run on a warm day...So make sure to drink a few glasses of water once you're back home to get your body back to a balanced state after your run or long walk.
When do you need to carry water while running ? How much water should you drink ?
Any walk or run longer than a few miles is going to require some portable running hydration.
The most common ways are bottles, belts and backpacks...
