Lately I've been taking my runs to the next level (you always have to push it) by doing my regular run, sprinting back to my apartment, chugging a beer or two, and going back out and doing another half run/three quarter run.
Anyone else do this shit? Beer hits your blood sugar pretty hard, dropping it, over a couple hours. But if you do it as a mid run thing (and eat a proper recovery meal immediately after) I'm finding it's just the right combo of impaired judgement and short term blood sugar/carbohydrate boost to get me going again.
Beer certainly does give me a lot of energy. The drunk kind of energy. The best kind of energy.
