The 2026 Jackass Half Marathon & 5K returns to Kellogg, Idaho on October 3rd for its seventh annual run. This top-rated half marathon and 5K race will take place starting in historic Wallace and ending in Uptown Kellogg along the paved Trail of the Coeur d'Alenes. Race morning finds runners gathering at the trailhead in Wallace where the crisp autumn air invigorates as temperatures hover around a comfortable average of 9.6°C, with skies mostly clear under a low UV index of 2.8 (Low). The race course offers scenic views along the winding Coeur d'Alene River and through the foothills of the Silver Valley during its most spectacular season. Since its inception in 2020, this event has become a beloved community fixture, attracting both local participants and visitors from across Idaho and beyond. In previous years, thousands have lined up to run or walk for charity, with all proceeds going towards supporting various community causes. The Jackass Half Marathon & 5K is not just about running; it's an opportunity to enjoy the natural beauty of Kellogg while contributing positively to its local charities. The course venue boasts a mostly downhill layout that makes it accessible and fast, suitable for runners at any level from beginners to seasoned competitors. Alongside the half marathon distance, there are also five-kilometer options including a Jackass 5K race and a one-mile Kid's Jackass Half Marathon designed specifically for younger participants. For those planning on running or walking, the course is described as firm yet slightly soft underfoot due to typical weather conditions in October. Expect temperatures ranging from a minimum of 3.8°C up to a maximum of 15.9°C with an average humidity level of 72.4%. Rainfall is minimal at just 1.9mm, while there's a slight risk of snowfall which remains unlikely due to the low UV index and ample sunshine duration of about seven hours.
