The History of Mud – Dirty Girl Style!

In 2011, Dirty Girl 5K Mud Run and Obstacle Course made its debut in three cities: Milwaukee, Denver and Buffalo.  The mud was abundant and the laughter contagious.  Women were ready to forget about their deadlines and “to do’s” for one glorious day.  They gathered their gal pals and rejoiced in finally being the ones to soak up the sideline cheers!  Yes, the Dirty Girl nation was born.  Never before had there been an event devoted solely to women, welcoming ALL fitness levels.

When it comes to maneuvering life’s triumphs and tribulations, we all feel better with a “bestie” at our side.  Dirty Girl is no exception.  That’s why we’re proud to have Bright Pink as an official charity chum.  Together, we’re focusing on empowering women to lead healthier, happier lives.  Bright Pink’s mission is simple: encouraging and educating women to understand the signs, symptoms, and risk factors of breast and ovarian cancer.

To this end, Dirty Girl is honored to have donated over $475,000 to date to support breast cancer prevention and awareness. For 2014, we have a goal of donating more than any previous year to support Bright Pink’s efforts.

Dirty Girl is a for-profit company passionate about promoting not only Bright Pink’s efforts, but also supporting cancer victims and survivors.  At each Dirty Girl event, up to 300 complimentary registrations are available to cancer survivors. If this applies to you, please email us at  Having the privilege of hosting an event at which these survivors, with their besties by their side, can maneuver and laugh their way to the finish line is awe-inspiring.  Sign up today to be a part of something truly magical, side-splittingly memorable and wonderfully muddy!
