OREFIELD, Pa. -

As many as 4,000 females are expected to participate in a Dirty Girl 5K event -- billed as a non-intimidating, fun mud run -- which will be July 12 on a farm north of Allentown in Lehigh County.

Jaindl AG has entered into an agreement to lease one of its agricultural sites to the Dirty Girl 5K Mud Run organization, which calls itself the nation's largest women-only mud and obstacle run series.

Dirty Girl 5K Mud Run consists of a 3.2-mile obstacle course designed to empower women and inspire them to break out of their comfort zone, while sharing team camaraderie in a non-competitive environment.

At Jaindl AG’s Raven Valley Farm, located in Heidelberg and Lowhill townships near the village of Schnecksville, the event will offer participants "a fun, exciting experience with beautiful mountainous views."

“The course will feature custom obstacles designed for women of all athletic abilities and the setting at Jaindl Farms is ideal for the best mud run experience possible,” said Tia Mattson, chief marketing officer at Dirty Girl Mud Run.

While the event is being promoted for women in the Philadelphia area, the farm is more than 60 miles from Philadelphia.

Participants will pay an $85 registration fee, which jumps to $100 after July 2.

Registration for the mud run event is still open, but registrations are filling fast.

No admission is charged for spectators.

Since its inception in 2011, the Dirty Girl Mud Run has been a proud supporter in the prevention of breast cancer, having raised more than $435,000 for research and related efforts.

“All proceeds received by Jaindl AG for this event will be contributed to the lead recipient and local charities,” said Luke Jaindl of Jaindl AG.

“At this year’s Dirty Girl event, Jaindl is looking forward to supporting Bright Pink, the foundation involved with Dirty Girl and focused on the early detection and prevention of prevention of breast cancer.”

Jaindl added: “We were very proud to make the Wounded Warrior Project our lead recipient for the 2013 Tough Mudder event. Local charities include the Miracle League of the Lehigh Valley, which was a beneficiary for the 2013 event.”

Dirty Girl has organized more than 70 events since 2010. There are 25 events scheduled for this year across the United States.

Parking will be on-site at Raven Valley Farm. The farm is accessible by taking Sell Road off Route 309 north of Schnecksville. There is a $10 per vehicle charge for all participants and spectators.

Dirty Girl is looking for at least 50 volunteers, who will be trained to work the event, keep runners pumped and hand out its pink shirts, among other tasks. Those  interested in volunteering may find more information online.
