From the Organizer
Our annual 5K runs through the Pleasant Valley subdivision and into the neighboring Fairfax County trail system.
For those really looking to demonstrate their summer fitness, take on the Aquathlon Challenge, a 150m pool swim followed by a 5K run.
In the afternoon, we'll continue our beloved neighborhood tradition with our dog swim, when the pool will be reserved exclusively for some very good boys.
All proceeds directly support the Pleasant Valley Pool in Chantilly. Your participation makes a vital difference in keeping this community resource thriving.
