Rules

The project involves designing and building a sled with a metal frame and running surface made entirely of concrete, and descending a steep snow-covered hill. The sled must weigh less than 300 pounds (136 kg), have a working braking system and have a safety cage to protect five passengers. Each competing team must complete a technical report summarizing the design, which is presented at a public technical exhibition.

Spirit

Teams traditionally choose a theme for their sleds; they often wear matching costumes and incorporate design elements into their technical display and sled aesthetic. This has become an important part of the competition, making up most of the award for spirit as well as the award for best form. Theme ideas are most often taken from pop culture or retro references, or are based on the team's home university/college and location.
