Trials Fever

Caitlyn Tateishi is the type of runner who is never satisfied.

She ran her first marathon in June 2015, finishing in 3:38:49, a few minutes above her Boston qualifying time. It didn’t take long for her to sign up for another one — and three months later, she qualified for Boston by more than 15 minutes.

Military Running

Brittany Charboneau tells her fair share of jokes, but she made a serious play for the Marine Corps Marathon record.

Aiming for 2:37:00, the Colorado-based comedian, actress and improv instructor took off after a few easy miles, grabbing the lead from 2015 and 2018 MCM winner Jenny Mendez and hitting the halfway mark at 1:18:05. Mendez eventually dropped out short of 20 miles.


News

For some runners, completing the 44th Marine Corps Marathon is a grand achievement. For others it’s “just a Sunday”. There were thousands of different stories that involved crossing the finish line of the rainy 2019 Marine Corps Marathon, but here is just a small piece of the many stories that make up D.C.’s most prominent race.

Ben Nilsestuen, 37, of Brooklyn, ran the marathon in memory of his friend, James Brophy, who died in December in a Marine training accident. Nilsestuen was not alone in supporting the memory of Brophy. All of Brophy’s college roommates, his old friends from high school, and his wife, were out to support the Marine’s memory by running the marathon.
