As we continue to live in a world of uncertainty and change, we have again been faced with a difficult decision. While we love racing with you, your safety has and always will be our top priority. Amidst the COVID-19 pandemic, for a variety of reasons, the 2020 Fairfax Four Miler has been cancelled.

What better way to ring in the new year than a run with thousands of your closest running buddies? Celebrating our eleventh year, the Fairfax Four is a favorite for its post-race pizza party and cozy sweatshirt premium!

Pacers Running runs our events rain, snow, or shine. We adhere to strict internal procedures related to course safety and work closely with our municipality partners and medical providers. If at any time we believe the course is or will be unsafe we reserve the right to modify, delay, or cancel the event. However, we do our best to communicate any changes or updates to our participants in real time via Twitter and our website. Please note that in our almost decade of producing events we have only canceled one event and modified two courses due to weather (this one included when in 2008 a downed power line of all things forced a double loop reroute!)
