About this race
Seneca Slopes 9K is a running race held on a December morning at Seneca Creek State Park in Gaithersburg, Maryland. The Montgomery County Road Runners Club organizes it as part of its free, low-key member race series. A separate paid registration is available for non-members.
The course is a 9K within the state park, with official results scored by gun time. One past edition recorded 98 participants, with James Fogg of Kensington finishing first in 36:28. The results indicate the field draws participants primarily from nearby Montgomery County running communities like Silver Spring, Bethesda, Germantown, and Gaithersburg.
