About this race
Welcome to the MCRRC Stone Mill 50 Mile Run!
This 50 mile trail run showcases the beauty of both the Seneca Greenway and Muddy Branch trails in Montgomery County, Maryland. The course traverses forested, rolling terrain on a primarily single track, dirt trail. There are small stream crossings. Most of the course drains well, but parts can be muddy in wet weather.
Volunteer!
As a participant in this event, we ask that you commit to volunteer 6 or more hours before race day with your local running club, any local race, work on the trails or any other running-related non-profit organization (such as Girls on the Run, Let Me Run, etc.). This is done on the honor system. No proof will be requested.
