How often should runners hydrate during a race?
The most important thing to consider is the length of the race and the weather conditions. During a short race, runners should aim to drink at least 6 to 8 ounces of water every 15 to 20 minutes. For longer races that last more than one hour, runners should strive to drink 8 to 12 ounces of water every 20 to 30 minutes.
