While many people would associate water or Gatorade with exercise, those people would be wrong, and the Irish Snug knows it. Every Thursday at 6:15 and 6:30 p.m., waves of runners head out from the pub, following a 5K route around Capitol Hill before returning at a sprint, walk or crawl. Why are they running? Because there is a free spaghetti dinner waiting for them. Oh, and lots of carbohydrate-rich $3 pints of beer.
