Meb Keflezighi, Olympic medalist, 2009 NYC marathon winner, and 5th place finisher in this year’s Boston marathon often completes long runs relying only water. And he’s probably a better runner because of it -The new rules of long run fueling
MY COMMENT: This is a concept first introduced by Greg McMillan, or at least that was the first time I had seen it, except we NEVER took carbs back in the 70s on long runs! I'll never forget running 2 hr 28 min in the heat and humidity on a hilly course in Arkadelphia, Arkansas (70 something degrees and 70 something humidity). We got plain water every 5 miles, and risked disqualification for taking anything else. Unbelievable!
