The Catoctin Crescent Association is hosting a 5K race/1K walk in support of the Loudoun County Volunteer Rescue Squad and the Douglass School.  $750 in prizes will be awarded to the largest team, the top three M/F finishers, and the top three winners in each age group. All runners and walkers will receive a free T-shirt. There will be live music, refreshments and massages! Come early to stretch with the experts. Register at www.onthecrescent.org/5k before Oct. 1 to avoid the increase in the entry fee. Sign up with three family members, co-workers or friends and save even more! The CCA is a not-for-profit organization that promotes local businesses along Leesburg's Catoctin Circle between Market and King streets.
