about the dirty dash

It took Brad Pitt years in the Montana wilderness filming A River Runs Through It and Legends of the Fall to turn him into the chiseled roughneck capable of harder core roles in Fight Club, Troy, and The Curious Case of Benjamin Button. There, it took him a lifetime to change from an elderly baby in Huggies to a baby-faced senior citizen in Depends.

Regardless of your choice of undergarments, it’ll only take you one running of The Dirty Dash to convert from boy to man and man to swine. 

The Dirty Dash is coming to town and making enough mud to turn the Clark Fork brown. It’s time to drop whatever inhibitions you may have left as you and your fellow Grizzly-lovers race through mud and obstacles and slide down one of the largest slip n’ slides in the country. We would say that your mother would not approve, but in Missoula, chances are she will be running right next to you. 

Missoulians’ relish getting dirty and can cowboy up to any challenge be it man, beast, or beastly man. You wear it on your bloodstained, trout-smelling, beer-soaked sleeves. You live in a place where you are more likely to be assaulted by a bear than a person, and you like it that way. A place where fishing is considered religion, and a cold Moose Drool at Charlie B's is at the top of the agenda at your weekly staff meeting. 

Other races give you the chance to test your mettle; now you’ve got a stage to wallow in a mud-hole. If getting dirty and having a beer with the rest of Missoula doesn’t sound like a good idea to you, you may be in the wrong city. Hell, you might be in the wrong state. Jeez man, are you American?

packet pick-up info

Charity Partner

Frenchtown West Valley Historical AssociationThe Frenchtown-West Valley Historical Association will partner with the 2014 Dirty Dash being held at the Flying “H” Stables Ranch.   The proceeds from this Dirty Dash Run will be used by the Historical Association to reprint the “Frenchtown Valley Footprints” historical book and as seed money to buy land and build a combined Community building and Historical Museum.
Frenchtown was the first permanent settlement in this area of the Missoula Valley.  There is a tremendous amount of heritage and historical artifacts in the area that are in dire need of being preserved before they are lost forever.  Your registration and participation in this event will be a major step in the beginning of a desperately needed facility for all of the Frenchtown Valley.
The Frenchtown-West Valley Historical Association and the Frenchtown Senior Citizens Association, who have already raised thousands of dollars towards a community building, have joined efforts to build a Museum and Community Building combined.  The Dirty Dash Run will be a major fund raiser from this joint venture.  The Frenchtown Community will provide volunteers to host and run this event to insure its’ success.
