Get ready for a beloved 5K through Arlington's Bluemont Park on a smooth, mostly flat paved trail, with both the start and finish line right in the park! You'll enjoy some local history too—the park sits on the grounds of the old W&OD Railway and even features a retired caboose. The race offers awards for overall top finishers and age-group winners (10-year divisions, both male and female), with free registration for DCRRC members and a $10 entry fee for non-members.
