Beet juice energy gel?
I’m typically pretty cautious when reports of a particular ingredient or 'super' food are linked to boosts in athletic performance, but like others, I’m intrigued by the possible endurance benefits of drinking beetroot juice. If you haven't been following the topic and this is the first you're hearing about the potential power of beets, here's the quick gist: A handful of studies performed over the past several years have found that consuming beet juice lowers the oxygen cost of exercise, due to the high concentration of nitrates found in beets(1-3, 5-8, 15).

When Geoffrey Mutai crossed the finish line at the 2011 Boston Marathon in the fastest time ever run (2:03:02) he gave a glimpse of the unthinkable. Although his performance was aided by a tailwind, the fact that Mutai was only a few seconds from 2:02 territory more solidly shifted the possibility of a human covering 26.2 miles in less than 2 hours from a question of 'if?' to 'when?'. While some people think we're still generations away from witnessing the feat, others envision it happening much sooner. I'm on the latter side of the fence and believe we'll see it occur in the next twenty years.
