At Tap 'N' Run, runners aren't out to claim the title of Fastest Runner. They're out to claim titles such as Best 'Stache, Celebrity Look-A-Like, or Largest Squad. That's because this 4K is a fun run in the truest sense: 21-and-over participants can run, walk, skip, or even potato-sack to the three beer stands set up along the course. They're given a 5-ounce brew at each and another 12-ounce bottle at the finish line. After using their finisher's medal to crack open that last beer (yes, it's also a bottle opener), they can head to the afterparty in hopes of claiming one of those race-day superlatives. One of the most sought-after awards is Most Unique Team Concept, as everyone's invited to dress up in costumes that at previous races have ranged from superheroes to ice-cream cones to runners running a race.
