The Crazy Muley Ultra is Alberta's only sand dune ultramarathon, featuring challenging 50K and 25K-ish trail races across unique landscapes including rolling hills and sand dune complexes. Participants can expect a tough course on mixed terrain with loose sand and minimal shade, promoting environmental responsibility by being cup-less; runners should bring their own reusable cups.

​

The race starts and finishes at the Sand Dune Liquor Store parking lot in Edgerton, with aid stations provided along the routes. The event also welcomes well-behaved dogs under specific leashing guidelines and concludes at a local bar offering discounts to celebrate runners' achievements.
