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.
The 2021 race is an RRCA National Championship Event. The RRCA Championship Event Series is the largest grassroots-organized running series in the U.S. with over 200 races participating that attract nearly 300,000 participants. The goal of the RRCA Championship Event Series is to celebrate and shine a spotlight on well-run, community-focused events and to award top performing runners in the open, masters (40+), grand masters (50+), and senior grand masters (60+) categories for both men and women.
As a participant in this event, we ask that you commit to volunteer 6 or more hours before 11/12/21 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.
