2023 Semper Fidelis Challenge

In 2023, the Semper Fidelis Challenge will now encapsulate the Marine Corps Marathon Organization’s three premiere events and bring them together in an exciting new way. Runners who qualify for the challenge will complete the following live events:

SemperFi Challenge 2023

Awards

Finishers will receive all three event medals, plus an exclusive challenge medal. Additionally, individuals will now have the chance to compete for category awards. This year, a runner’s aggregate finishing times from the Marine Corps 17.75K, Marine Corps Historic Half and the Marine Corps Marathon will qualify an individual for a full array of Overall, Masters and Grand Masters awards for men and women. Who will be our 2023 Semper Fidelis Challenge Champions?

Please note that a finish in the Devil Dog Double or MCM50K no longer applies to the Semper Fidelis Challenge due to logistics with the new awards.
