9th Annual Tom LaMonica Memorial Twilight 5K Trail Run & Festival

  • Genesee Valley Outdoor 1717 Rayville Road Parkton, MD, 21120 United States (map)

Online Registration is now closed. Registration will be available on-site prior to the race.


Genesee Valley Outdoor Learning Center is a nonprofit organization founded by Tom LaMonica in 1981. Tom was a teacher and coach at Friends School of Baltimore and passionately served as our leader until his passing in September 2010.

This 5K run is a memorial to our founder and our biggest fundraising event!

Tom built Genesee Valley to provide a space for groups to become better teammates and classmates through physical challenges. We continue that tradition today by offering Summer Camp and Team building programs to students and adults that focus on communication, confidence building, persistence, leadership, and creative problem solving.

Proceeds from this event support our scholarship fund for students who could not otherwise afford to attend Genesee Valley. Scholarship students either participate in our Team building programs with their class as a school field trip or attend a full week of Summer Camp.

Weather & Event Cancellation

Please review the Charm City Run Weather and Event Cancellation policy here prior to registering for this event. If you have any questions about the policy please email us at prior to registering.


We need volunteers to help us with many tasks throughout the morning of the race: setting up the check in tables, taking photos, distributing water, and much more. We could also use some help getting the course ready the couple weeks prior to the race. Email us if you are interested in helping.
