So yes, Marathon runners need and wear hydration packs.

How Big Of A Hydration Pack Do I Need?

Many of us especially the big guys ask this question, “How big of a hydration pack do I need?” 

Well, it depends on the activity you are about to carry out. 

If you are going for a hike, you will a hydration pack of 21 liters or more. Any hydration pack over/about 21 liters is usually designed for hiking.

 How Much Water Should I Drink During A Marathon?

Calculating how much water you need to drink during a marathon can seem intimidating but it all depends on your body size and pace, the heat and humidity, and your sweat rate.

The maximum amount you should drink during running is the amount that can empty from your stomach or the amount that you’ve lost as sweat, whichever is less. Drinking more water than you’ve lost brings the risk of hyponatremia. 

Research has shown that most runners’ stomachs can empty only about 6 to 7 ounces (180 to 210 ml) of fluid every 15 minutes during running, representing about 24 to 28 ounces (720 to 840 ml) per hour.

If you drink more than that, the extra fluid will just slosh around in your stomach and not provide any additional benefit.  

 However, calculating how much water to drink during a marathon can be very simple if we take Sam Murphy‘s idea into account;  “Drinking when you’re thirsty!”
