Actor Sean Astin, star of "Rudy," "Lord of the Rings" and recently, "Moms' Night Out,"
will participate in the 39th MCM. Astin served as the honorary starter at the 2013 Marine Corps Historic Half, completing the 13.1 mile run in 2:11:58.

MCM registered runners no longer able to participate in the event may now officially transfer their entry to a Marathon hopeful or switch into the MCM10K. It is up to the individuals to find each other to execute a runner-to-runner transfer. The MCM Facebook page is a great way to connect. When transferring an entry, runners do not receive a refund on registration fees from the MCM. Any such monetary transactions must be handled directly between the transferring runners.

The registered runner must complete the online form located in the MCM's "Transfer Guide: from Runner to Runner" on the transfer page of the MCM website. MCM runners will follow the detailed instructions provided and include the new runner's information. An email will be sent to the transfer recipient with an individualized link. The new runner must complete the form and register for the 39th MCM within 72 hours. The new runner will also pay a $40 fee to finalize the transaction. There are no fees for the runner initiating the transfer.

Later this summer, the MCM will offer the deferment option for runners wishing to participate in 2015 instead of 2014. The MCM deferment option will be available beginning Aug. 1 and will conclude when the program reaches capacity. The fee to defer to the 40th MCM is $60. 

Runners are invited to post on Instagram in-training and in-action photos in front of scenic locations, wearing MCM apparel or highlighting a scene certain to inspire. Be creative and use #RunWithTheMarines. Photos posted by July 11 will be collected and incorporated into the "MCM Faces of Motivation" video to be released in August. Remember to add the hashtag to the image.
