    Our Rock the Run 5K started in 2015 to celebrate our 60th Diamond Anniversary of The Hope Center at Hagerstown Rescue Mission and to bring the community together to help raise support and awareness for the homeless and hungry in our community.

    Rock the Run 5K allows us to bring businesses, runners, walkers, competitors, and volunteers together to have fun, share some laughs, run or walk a few miles, and raise money for those in need. This year's fundraiser will help us convert our front porch into a 4-season emergency weather shelter.

    We encourage our participants to have fun with costumes and accessories and show us your pirate or princess side! We'll be making this event a little more exciting with some pirate & princess-themed touches to everything. But most importantly, we want you to have fun because you're supporting a great cause and doing something amazing for our community. So start talking it over with all your running friends, encourage others to join you, and then grab that eye-patch, tiara, and your running shoes for Rock the Run: Pirates vs Princess!

    *NEW DATE in 2026! Run with us on JUNE 6th!

    The 45th Annual Gary Brown Memorial C&O Canal Five Mile Run event will be held on the C&O Canal Towpath in Williamsport, MD. This event is geared towards all levels from beginners to advanced runners.

    The Legacy of Gary Brown

    In the 1960's, Gary Brown was a star distance runner for Martinsburg High School, Shepherd College and the Cumberland Valley Athletic Club.

    Gary went into high school teaching and coaching after graduating from Shepherd College. He developed one of the nation’s top distance programs. In the mid-1970's his Handley High School Boys Cross Country Team was the number one ranked High School Cross Country Team in the United States.

    Sadly, Gary passed way from cancer in the winter of 1981-82, prior to his 35th birthday.

    The C&O Canal Five Mile Run —which dates back to 1970– was re-named in Gary’s honor in 1982. Gary’s high school runners would use the late-August-held C&O Canal Five Mile Run as an “End-of-Summer-Training Fitness Test.” His teenage boys would routinely take six-to-eight of the top-ten places —running against collegiate and post-collegiate standouts.
