The Marine Corps Marathon Organization (MCMO) today announced that registration for the 46th Marine Corps Marathon (MCM) opens to the public on Wednesday, March 10 at noon Eastern.
The 2021 MCM Weekend is currently scheduled as a virtual event with runners from across the country participating in the MCM, MCM50K or MCM10K from October 1 through November 11. Ambitious runners can once again sign up for the Semper Fidelis Challenge, a two-event challenge including either the Historic Half or the Devil Dog Double in May 2021 and the MCM or the MCM50K in October 2021. Runners may also pursue the Trifecta, a unique opportunity to participate in and complete all three MCM Weekend distances within the designated timeframe.
