Twelve Years of Mud. One Very Good Cause.
The Gretna Gritty is Gretna Glen's annual 5K mud run fundraiser, and the 2025 edition marks our 12th year running it. Twenty-plus obstacles. A 5K loop through the rugged, hilly terrain of the Mt. Gretna area. Challenges of balance, brawn, bravery, and buffoonery. All of it designed to be less of a race and more of a ridiculously fun morning.
Walkers welcome. First-timers welcome. Teams, solo runners, and spectators welcome. You do not have to be in peak shape to show up and have a great time. You just have to be willing to get muddy.
Every dollar raised through the Gritty, excluding participation costs, goes directly to Gretna Glen's ministry. This event is how we fund scholarships, facility improvements, and the programs that shape kids' lives year after year.
What to Expect
Twenty-plus obstacles across a 5K course, a kids' run built for the small humans, and a finish line that feels earned.
5K Mud Course
Wind through the hilly Mt. Gretna terrain with 20+ obstacles built for the course. Wooded trails, open fields, and creek crossings across the property.
Balance, Brawn, Bravery, Buffoonery
The obstacles are designed for fun, not punishment. Crawl, climb, swing, splash, and laugh your way through each one.
Nitty Gritty Kids Run
A 1.3-mile mini course built for kids ages 5 to 11. Same dirt, same spirit, scaled to small legs and big imaginations.
Medal, T-Shirt, Lunch
Every registered runner gets a finisher's medal, a Gretna Gritty event t-shirt, and lunch at the post-race celebration.
Post-Race Celebration
Cross the finish line and keep the morning going. Food, music, and the kind of atmosphere that only comes after 600 people get muddy together.
All Paces Welcome
Runners, joggers, walkers, and crawlers all belong here. The Gritty is not timed and never has been. Show up, move at your speed, finish muddy.
Every Finish Line Funds a Future
Gretna Glen is more than a weekend on the calendar. It is a place where kids meet Jesus, build confidence, make lifelong friends, and discover the outdoors. Every Gritty participant and spectator helps make that possible for another camper.
When you register for the Gritty, you are not just signing up for a mud run. You are investing in summer camp scholarships, outdoor education programs, facility improvements, and the next generation of campers who will call this place home.
