This race was previously named the Bald Mountain Triathlon, and was held at Bald Mountain Ski Area in 2020, but moved to Deyo Reservoir for 2021 and 2022 and was renamed in honor of the Deyo Family matriarch in 2023.
The race will be located at the Deyo Reservoir outside of Weippe, Idaho. The swim will take place from the sandy beach and traverse 300 yards before transitioning to mountain bike gear and leaving the reservoir along Schmidt Mill Road to 3-mile Road to Fidler Road and then along a forested trail back to 3-mile Road and the reservoir, approximately 13 miles. The run course will be the well-travelled 2.2 mile trail around the reservoir. There will be a single transition area.
