Tucked away in the suburbs of Washington, D.C., the Frederick Running Festival is one of the hidden gems of the running community. The festival features four races, which all finish at the Frederick Fairgrounds. Runners can experience a big time race with small town charm with the added value of off-site packet pick-up in the suburbs of Maryland. Choose between a half-marathon and two-person team relay on Sunday or the 5K and Kids Fun Run on Saturday.
