Hydration Demands for Running a Marathon
A two-time Ernst & Young Entrepreneur of the Year, Ryan Wuerch founded and chairs the board of DOSH. Outside of his professional endeavors, Ryan Wuerch enjoys running marathons.
Preparing for a marathon involves more than just training your body to handle the rigors of the race. One of the most important things marathon runners need to monitor, both in the days leading up to and during the race, is water intake.
Dehydration is a serious problem that can negatively impact your performance. Conversely, if you drink too much water, you can suffer from hyponatremia, which, in its most serious instances, can lead to brain swelling that causes seizures, among other life-threatening complications. A 2005 New England Journal of Medicine article showed that 13 percent of the participants in the 2002 Boston Marathon may have been affected by the condition.
Hence, it is important to stay hydrated in the lead-up to a race, but to avoid drinking water when you're not thirsty. Do the same during the marathon. Most runners consume less than 16 ounces of water per hour when racing.
