Giving up drinking while marathon training: Worth it?

I joke a lot that I run for beer — except it’s not really a joke. Seriously, if there’s anything better than a cold beer after a long run, I don’t know what it is. (OK, maybe Bloody Marys at brunch after a race. Those are also pretty legit.)

But would I be a better runner if I stopped drinking during marathon training?

A recent article in Women’s Running took a look at the drawbacks of drinking during training, including dehydration, empty calories and its negative effect on your muscles.

The author, Charlie Watson, writes that studies show alcohol consumption decreases the use of glucose and amino acids by skeletal muscles. This, in turn, hurts your energy supply and metabolic process, and it also hurts your body’s ability to store glycogen, which you need for those long runs. As a result, you’ll be slower, and you’ll crash sooner.

“Ultimately, it’s up to you. Personally there have been training cycles filled with weddings and bachelorette parties where I wouldn’t have wanted to give up alcohol,” Watson writes.

I can certainly relate to that.

And honestly — I don’t know if I could do it! To be honest, I like drinking! And while I don’t get slammed the night before a race (anymore — learned my lesson after the 2013 A10) I usually have a beer or two with my pre-race dinner and I’ve always been fine. Even before marathons. Moderation is obviously key, of course.

But maybe I’d run even faster if I abstained.

Watson, the author of the article, said she gave up drinking while training for a BQ, which is what I am gunning for, as well. Perhaps it is something I should consider.

Have you ever ditched drinking in the weeks before a big race? If so, how did it affect your training and your race time?
