The Course is a mix of desert, grass, horse-race track, abandoned horse-race track, and graveled road, with a small bit of asphalt, often covered in snow during December. You start off in the start corral right outside the doors of the Bonneville County Fairgrounds Exhibition Hall, through a bit of grass, across the edge of a parking lot and then cross a road, that gets you into Sandy Downs Park. We'll cross some dirt, a bit of horse track and then skirt the Grandstands on grass. We'll then get a full 1/2 mile on the race track. We'll then follow dirt road to the half-way point, wander over by the Snake River BMX Track,  and some old horse barns, then a 100 yards of deep sand, followed by a stretch of grass. We'll get another stretch of about 400 yards of sand through some trees and along a canal, before coming to an abandoned horse track that looks old, tired and beaten down (pretty much a mirror of yourself), finally we'll follow an abandoned dirt road to an makeshift exit from the park, then loop around Bonneville County's Fairgrounds and a bunch of corrals to make sure we get the distance exactly right and back to the start. After a few loopy laps of wandering through the desert/horse facilities you'll know why this one is called "Dizzy Horse." You'll get between 40 and 80 feet of elevation gain per lap.
