Run one, two, three, or four Friday evenings in April at our Crystal City 5K Fridays Series. April 6, 13, 20, & 27, 6:30 p.m. sharp, outside Crystal City Courtyard Green. One of the most popular and fun 5k races in the metro area, it’s a great way to work off your week and meet others for happy hour (and a drink too). Runners will receive post-race drink tickets that can be used at select Crystal City watering holes. Run the whole series and get a great entry fee ($5 off PER race) and a race premium.
