Drinking More Water Doesn’t Affect Marathoners’ Performance Stephen Fung April 25, 2007 Marathon runners are under the false impression that drinking lots of water before and during the race will improve their performance and keep them cool. However, a recent study shows that normal hydration of the body is sufficient to keep a runner going. They should simply listen to their bodies and drink when thirsty, but further intake of liquid will not make them win the race. Runners in today’s London Marathon may be tempted to down several litres of water to keep their cool and achieve their best time, but large fluid intake does not achieve either, according to a sports scientist from the University of Exeter.
