About the Event

Come out for summer fun at the Pleasant Valley Pool. Enjoy a refreshing pool swim and run with our Swim/5K Aquathlon or skip the water and stay dry with a 5K fun run! In the afternoon, we'll once again be holding our dog swim, when the pool will be only for a dogs only swim time!

Proceeds directly support the Pleasant Valley Pool in Chantilly! We've also partnered up with two great non-profit charity partners which you can also donate to. The local Western Fairfax Christian Ministries Food Pantry, which was formed in 1987 by members of 12 Chantilly and Centreville churches, WFCM provides food and financial support to reduce hunger and the risk of homelessness among residents of western Fairfax County. Our second charity partner is the Major Lucas Legacy Foundation. The Major Lucas Gruenther Legacy Foundation was founded in 2015 to bestow scholarships to Americans for the advancement of educational goals and self development thereby strengthening and benefiting the community at large through individual enhancement.
