The Sabino Canyon Sunset Run is a unique 7.4 mile event that winds its way into (and out of) Sabino Canyon in the Catalina Mountains. Known as one of Arizona's most beautiful running venues, the US Forest Service has graciously opened the canyon for this annual organized running event. Interested? This run is limited to the first 200 entrants and spots fill up fast.
