Yours in mud,
The LC Valley Down and Dirty Mud Run crew


Big mud. Big fun. Right in your backyard.

The LC Valley Down and Dirty Mud Run made its rather messy debut in 2014 and has grown bigger and better every year since. Construction of the new LHS forced the event to move to a new home and COVID-19 forced us all to watch and wait. 

Consider this your official invitation to join the mud and mayhem – your invitation to run, jump, hop, crawl, bounce and splash your way to the finish line alongside your brave and adventurous neighbors from across the Inland Northwest.

Registration coming soon...

About the race

What is Down and Dirty?

The LC Valley Down and Dirty Mud Run is part cross country run, part obstacle course for adults and children of all ages and athletic abilities. And don't worry! It's not a race unless you want it to be. Slow down, get muddy and enjoy the opportunity to get real dirty without having to make excuses.

When, where and how far?

The race is scheduled for this August. We'll have a short course, long course and a Mini-Mudder for kids. There's no age limit (top or bottom) for the big course, but runners should be able to handle all (or most) of the obstacles themselves and our youngest entrants should be running in the same heat as a parent or guardian.

Can we run in the same heat as our friends?

Yes. Participants can designate which heat in which they would like to compete. Your group should register early to make sure there is room for all in your chosen heat. The Mini-Mudder will be a run-as-you-come affair, with the course open from 9 a.m. to noon. Kids can run multiple times if they have the energy, and parent are welcome to run alongside.

How much to participate?

Cost ranges from $45-75 for the main course (register early for the best deal!) and includes the race, a T-shirt, finishers award, and chip timing. There's also a post race shower and party. The Mini-Mudder costs just $20.

What about spectators?

Nonparticipants are in for a treat. The event will be held on the best spectator course in the region. Friends and family will be able to share in your muddy exploits without leaving the start/finish area. They can also join in the post-race party. Make sure they bring a camera to capture the fun.

I'm in! Who else benefits?

We are a strong supporter of local non-profits and charities. In four years of operation, the LC Down & Dirty has donated over $62,000 to charities including:

  • Wounded Warrior Project
  • Idaho Food Bank
  • Liberty Theater Preservation Alliance
  • L.I.F.E. Board
  • Gritman Diabetes Awareness
  • Willow Center
  • YWCA
  • Opportunities Unlimited
