Quantico Tri

The Quantico Tri has been replaced on the 2020 MCM Event Series schedule by a new virtual option. The Marine Corps Duathlon challenges athletes to run-bike-run while earning a spectacular finisher medal and participant shirt.

COVID-19 Update

Replacing the Quantico Triathlon is the virtual inaugural Marine Corps Duathlon. This new dual skilled event will feature a 5K run, followed by a 20.4K bike ride and end with a 5K run.

Registration for the new Marine Corps Duathlon event is now open. Participants previously registered for the Tri had the option to:

  • Switch to an August 22 event on Marine Corps Base Quantico
  • Transfer to the virtual option
  • Defer the fee for credit to MCMO events through November 2021 not including the MCM or MCM50K.

Runners were emailed further instructions including a link to their personal event change form. This link was exclusive to the individual runner and may only be accessed through the email address provided by participants during registration.
