Should I drink water before running? How much to drink? How long do you drink before running? Can I drink after running? How long can I drink? Thank you for your suggestions, but please answer thank you from a practical point of view. Before running, it is recommended to drink 355-470 ml of water and pour it into a cup, probably a cup or half a bottle of mineral water. It is recommended to drink water 15 minutes or more before running, otherwise the water will be uncomfortable when it keeps shaking in the stomach with the running body. The suggestion in running is to drink a few mouthfuls every 20 minutes, which is about half of that of marathon disposable cups. You can drink it at any time after running. There is no upper limit on the amount of water you can drink after running, and you usually feel thirsty after drinking it. It should be noted here that it takes time for the water just drunk to be transported to the body cells, so drinking water hard in a short time may not immediately quench your thirst. In addition, if the running distance is longer than 10 km, you can consider supplementing the electrolyte of functional drinks or eating something supplemented with salt and sugar while drinking water. In order to avoid the adverse reactions caused by the rapid decrease of electrolytes and blood sugar in the body after drinking water.
