The Great Northern Concrete Toboggan Race (GNCTR) is an annual event that challenges the creativity of engineering students.

[2] Since its beginning, GNCTR has grown to include universities and technical schools from across Canada with occasional entries from the United States and Europe.

The project involves designing and constructing a toboggan with a metal frame and a running surface made completely out of concrete and racing it down a steep snow-covered hill.

The sled must weigh less than 350 pounds (158.8 kg), have a working braking system, and be fitted with a roll cage to protect its five passengers.

By the mid-1990s, this practice had changed to an alternating scheme between Western and Eastern Canadian schools; the dividing line is the Manitoba-Ontario border.
