I stood at the end of a ridiculously grueling trail amid the red cliffs of Western Colorado. Around me, runners enjoyed various cold, locally brewed beers wrapped in neoprene sleeves emblazoned with a sketch of the mountain we'd just torn up and down and the words "I survived the Summit and Plummet." It was not yet 11 a.m.; we'd just finished one of the hardest five-mile runs in North America. We'd earned those beers. At least, that's what we told ourselves.
It's a common ritual among my running buddies. We run, then we drink. And we're not alone. The outfit that organized today's informal run often congregates at Grand Junction's Kannah Creek Brewing Company following its weekly trail runs. Paonia's Elegantly Attired Running Ladies, my women's group, meets every Friday evening for a run that finishes at Revolution Brewing. And then there's the famous Hash House Harriers, with chapters around the world, which calls itself a drinking club with a running problem. Among runners, coffee is perhaps the only beverage more popular than beer.
Turns out the research on alcohol and exercise is as herky-jerky as our culture's attitude toward the bottle. Most early studies investigated alcohol's potential as a performance enhancer. It seems ridiculous now, but during the 1904 Olympic Marathon, U.S. gold medalist Thomas Hicks was given a mixture of brandy, strychnine, and egg whites in an effort to gain a competitive edge. Many coaches then believed alcohol boosted energy.
In more recent years, not surprisingly, that belief has been largely disproved. One study on sprint-and middle-distance runners, for example, found that at most distances the more alcohol the athletes had, the slower they ran. Still, another study on male cyclists found that drinking the equivalent of two shots of hard liquor one hour before exercising didn't give athletes any distinct advantages, nor did it significantly harm heart rate, blood pressure, or oxygen uptake. Even a hangover doesn't seem to diminish your aerobic capacity—it just makes you feel lousy, so you underperform. But at the same time, there's evidence to suggest that drinking after a workout might spoil recovery of muscle damage and reduce the amount of energy stored in muscles.
So what was all this conflicting information really telling me? Being a former scientist, I had my own theories about how drinking and running mix, and I couldn't resist putting them to the test. The nearby Colorado Mesa University had just opened the Monfort Family Human Performance Research Lab, a state-of-the-art exercise-science facility that seemed like the perfect venue to explore alcohol's effects on running performance. My friend Gig Leadbetter, Ph.D., coaches the school's cross-country team and is an exercise scientist at the Monfort Lab. He's also a home brewer and winemaker and, without any arm-twisting, agreed to put together a study for Runner's World.
