Fuel Of The Week: Water

As the summer heat skyrockets, so should your water intake.

You know you need to be well-hydrated on the run, and if you find yourself trying to lose weight, it’s another reason to turn to the tap.

“Being dehydrated by just 2 to 3 percent can impair aerobic performance by up to 10 percent,” says Prudence Athearn Levy, a registered dietitian, licensed nutritionist and trail runner in Edgartown, Mass. “And, being even slightly dehydrated makes it more difficult for you to lose weight.” She says to aim for eight to 10 glasses of water every day.

The people at CamelBak have a vested interest in helping you fill your bladder—the one in your backpack—more quickly. So when customers complained about how slow water purification pitchers made by the likes of Brita or Pur are, Camelbak decided to expand. Designed to get rid of chlorine taste and smell (not lead), the Relay pitcher ($37; camelback.com) is indeed much faster to fill, which can be really helpful when you need to fill up water bottles, or any other hydration device, before a run.
