Butterfield Canyon Marathon

The Butterfield Canyon Marathon returns to Herriman, Utah on August 8th, offering runners a challenging yet rewarding course through the scenic trails of Butterfield Trailhead Regional Park.
Participants will gather at the park's trailhead, located along Herriman Highway. The race starts early in the morning with temperatures ranging from mild to warm as the sun rises over the surrounding mountains and the Kennecott Mine looms nearby. Runners can expect a well-marked course that winds through dense foliage and offers stunning views of Utah’s landscape.
This event has been running for several years, attracting hundreds of runners each year who come together not just for competition but also to support local causes and enjoy community spirit. The Butterfield Canyon Marathon is known for its affordable registration fees and generous amenities like custom finisher medals and free race photos provided by Xotio Media. Participants are encouraged to view the event’s website for detailed course maps, additional information on aid stations, and other races offered in partnership with Salt Lake Running Company.
The marathon takes place entirely within Butterfield Trailhead Regional Park, featuring a hard and dry trail surface that offers steep climbs and rewarding single-track downhill runs. The half marathon starts at 6:15 am from the same location but follows a slightly shorter route of just over 21 kilometers. Both races are designed to challenge runners with varied terrain and elevation changes.
On race day, temperatures will range between approximately 18°C and 30°C, making for comfortable running conditions despite the early start time. Humidity levels average at around 38%, while there is a small chance of light rainfall due to an expected total precipitation of about 1.6mm over 12 hours and 11 minutes. UV index will be high at 7, so runners should apply sunscreen for protection.
