Murph—Why We Do It
MURPH: WHY WE DO IT
The Murph Challenge is one of the most popular fitness challenges out there. You might have heard about it or even participated in it at some point. It’s not just a physical exercise challenge; it’s also a social activity where participants are encouraged to meet each other and bond over their love for running.
In fact, the Murph Challenge was created with the purpose of promoting health and fitness among its members. A typical Murph involves completing a set amount of miles within a certain time period. Some runners choose to run as many miles as they want while others only complete sets of five or ten miles. There are no official guidelines for what constitutes a “good” Murph.
It’s all up to the individual runner. However, the Murph Challenge does encourage runners to keep things fun and positive throughout the experience. That’s why we don’t require any particular training plan or diet regimen. Participants simply need to show up ready to go!
What Makes a Good Murph?
A good Murph requires that you’re prepared for whatever obstacles may come your way along the way (or after). It’s important to stay hydrated, keep your energy levels high, and maintain a positive attitude throughout the event.
The Murph Challenge was named in honor of Navy Lieutenant Michael P. Murphy, a Navy Seal who was killed during battle in Afghanistan on June 28, 2005. He was awarded the Congressional Medal of Honor for his courage and bravery during his final mission. To this day, he is an important symbol of the U.S.
Navy Seals, which is why the Murph Challenge has become popular among military personnel and their families.
