The second annual Holiday Valley Mudslide is a mud run that’s FUN. Yes, you’ll get muddy. Yes, there is running. Yes, there are eight obstacles but NO fire, NO barbed wire and NO electric shocks! The 3.5-mile course starts at the top of the mountain at Spruce Lake (we’ll even give you a ride up on a chairlift) and runs along the ridgeline then down the hill. The 5.4-mile course adds a bit of uphill running, just in case you’re feeling especially tough.

There is a maximum of 2,000 competitors. Registration is $60 for the 3.5 OR the 5.4 mile run until June 1, and starting June 2, registration is $75. The Kids’ Race is $5 (up to age 12) and they can register at the starting line. Day-of-race registration/packet pickup (if available) is from 8–10 a.m. at the Mountain Sports Center, next to Yodeler Lodge. You must pre-register before June 1 to be guaranteed a T-shirt.

All competitors will receive a goody bag and a super cool finisher’s medal plus a hot dog and two beers (or beverages). If you’re thinking about entering, do it now because we’re limiting the field to 2,000 competitors. Preregistration is available at

To be announced — fun events for Friday night, so plan ahead to stay overnight at the Inn or the Tamarack Club. Beat the rush and pick up your race packet on Friday from 5–8 p.m. at John Harvard’s Brew House at the Tamarack Club at Holiday Valley.

Course Route

The event will start in waves of 100 people per wave at 10 a.m. from Spruce Lake, beginning with the long course runners. A ride to the start on the Spruce Lake chairlift is included in the entry fee. Please allow 45 minutes to get from the base to the starting line at Spruce Lake! Spectators may ride for $5.

The 3.5 mile-course goes from Spruce Lake, across the cross-country trails to the top of Eagle, down Woodstock, across Explorer to Morning Star, then through the woods and across Mardi Gras, down Holiday Run to Edelweiss with a finish at the Training Center. The short course elevation has a drop of 600 feet — downhill!

The 5.4-mile course adds a loop from Eagle across to Cindy’s, down a logging road to lower Bear Cub and back uphill to Explorer. This section is so steep we’ve installed ropes to help you scramble up! You’ll navigate eight obstacles along the trail and the final challenge is a giant mudslide down lower Yodeler. Your medal will be awarded at the finish line. Prizes will also be awarded to the overall three fastest males and females. A course map with contours is available at

The Kids’ MiniMudslide course is 1/2 mile long and includes two obstacles plus the mudslide. Start and finish is at the Training Center. The MiniMudslide takes place after the Mudslide is complete, at approximately 1:30 p.m. Register your child at the start line for $5.

Check in, day-of-race registration and a bag check are from 8–10 a.m. at the Training Center at the base of Yodeler. After your run, you can shower under the snow guns and changing facilities will be available. The post-race party to end all parties starts at 1 p.m. with hot dogs, beer, music and craziness. Costumes are encouraged, and prizes will be awarded to the most creative.

Our photo service will be out on the course capturing your muddiest moments. They’ll be set up on the Yodeler deck where you can view and purchase your photos, or go online to order later.

The Post Race Party!

Tunes, games and plenty of liquid refreshments will be at the post race party on the Champagne Sundeck, just outside the Yodeler Lodge. Starting at 11:30 a.m., competitors will receive a free hot dog and two beverages. Friends and family are welcome to purchase food and beverages and join in the fun. DJ John Barry will keep the party goin’ on. Bring your (friendly) dogs, Frisbees, hula-hoops and smiles. Be sure to wear your medal in town after the event and on Sunday for the many special offers from merchants and restaurants/bars!
