What a beautiful day! Thank you to everyone for being part of it!
Will be updated for 2026 late winter.
The Hairy Gorilla Half Marathon & Squirrelly Six (.3*) Mile is part running race, part costume party, and is truly among the most unique events you'll ever do! Be on the look out for gorillas that have gone bananas, nutty squirrels, graves with your own names on them, and other inanity to keep you smiling and enjoying the beautiful views that await!
Join us in 2025 for our 21st year of festive running mayhem at an event that has been dubbed the Best Costume Trail Race in America by Runnersworld!
*The Squirrelly Six is now approximately 6.3 miles.

Get ready for a great time! It's all about Halloween at this event - you are highly encouraged to dress up. Our volunteers will be costumed, we make a grave yard with the names of many of our pre-registered runners, and the course is even decorated in sections to be very spooky!
Post race, you'll receive a sweet finisher's medal and AWESOME post race food! Do note that there is not a merchandise item included with your registration.
Want to see something adorable? Check out this ~Half Mile kids event! While open to children 12 and under, most who participate range in age from 3 to 6 and always come in costume. Entry is $5/child and includes a custom finisher medal and post race snacks.
While you may have them on-site at the event, you are not permitted to participate with pets or strollers.
Be part of the Halloween fun! We welcome you to join us as a volunteer and help make it a true Halloween delight!
The 2025 race start/finish area has moved slightly from 2024!
The event will utilize the same new course as what was used for the 2025 Thacher Park Trail Running Festival, staged from Hailes Cave Pavilion. This uses the same parking lot prior year HGH/SS participants have used and is a return to the staging location used prior to 2015.
Note: The Squirrelly Six Mile is now the Squirrelly Six (point ~3) Mile. Save some juice for that extra portion! (The Hairy Gorilla remains 13.1)
Full Course Google Map (Shows both races on a single map)
Both races are run together. Everyone runs the same first 10K. From there, all doing the 13.1+ continue together to complete the 13.1.
(These are the same courses as used at our August Thacher Park Trail Running Festival.)
Aid Stations provide water refill. And also candy. If taking candy, we PREFER that you leave the wrapper at the aid station. Your only other option is to PACK IT OUT. Do NOT litter.
