At Circle Brewing's 0.5K micro marathon, all runners are divided into heats, and each runner is given two pints of beer with a fill line to hold while running. Runners who spill below the line during the run will be disqualified. Prizes will be awarded to the winners of each heat, with a final heat to find the fastest and most careful runner of the day. Attendees can also stop by the RunLab tent to grab a complimentary massage (with a beer in hand for proper hydration). There will be food available from Ze Wurst. Proceeds will benefit Friends of Austin Animal Center to support the city shelter.
