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.

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.

The Butterfield Canyon Marathon offers both marathon (42.2K) and half marathon (21.1K) distances to cater to a wide range of participants. Early registration fees are $85 for the full marathon and $60 for the half marathon, increasing incrementally as race day approaches.
