The Dirty Girl Mud Run, an untimed 5K that raises money for breast cancer research, is set at Old Tucson Studios March 2.


The Dirty Girl Mud Run has left a mud trail across the U.S. and it is making its way to Tucson to dirty things up a bit.

Several hundred participants are expected to hit the mud running when the event takes place at Old Tucson Studios on March 2.

The untimed 5K, which raises money for breast cancer research, started in 2011 with five events in Wisconsin. Now, Dirty Girl has more than 60 events nationwide, with some claiming as many as 20,000 runners in a single race.

"Our participants really helped spread the word and got behind the brand. Being that it is an untraditional 5K, untimed and non-competitive, it is all about getting outside with your girlfriends and doing something fun," Andrea Neukom, Dirty Girl's marketing director, said in a telephone interview from Wisconsin.

Dirty Girl has partnered with the National Breast Cancer Foundation, and last year exceeded the initial $250,000 fundraising goal. Organizers hope to do the same with this year's goal to raise $1.5 million.

Dirty Girl runs feature an 11-obstacle course that welcomes women of all athletic abilities. Obstacles range from the "Utopian Tubes" tunnel crawl and the "PMS (Pretty Muddy Stuff)" mud pit, to "The Hangover" - hanging tires and more.

Fans find them challenging, but not intimidating.

"I like the girl mud runs because there are no electrical fences or barbed wire and its not competitive. I just like to have fun with it, just the spirit of having fun and being silly with your friends," Denise Mestanza-Taylor, who participated in the Tampa Dirty Girl race in Florida earlier this month.
