See Rules in the Demolition Derby Entry Packet
Demolition Derby is a generation-binding, intense, non-stop, heavy metal mayhem of collisions; a nerve wracking, knuckle busting prep in the pits where men and women cage their fury and unleash it when they hit the dirt. It is a contest where cars compete to be the last one moving. Audiences are treated to the pandemonium of cars crashing into one another. This event promises dents, dings, dirt, and destruction, everything that audiences expect from a Demolition Derby. Get up close and personal with the cars and drivers with a Pit Pass (pit pass has no access to beer garden).


Superintendent: Routt County Fair Royalty
The fourth annual Routt County Fair Stick Horse Rodeo will be held during the Demolition Derby on Friday, August 19th.

There will be stick horse barrel races, bronc riding, and bull riding! The stick horse rodeo is FREE and put on by your local Routt County Fair Royalty Court. Hope to see you there!
