About
UpRiver Running Fall Races brings a trail day to Thunder Bay each fall, with distances that suit both longer trail efforts and shorter community runs. The 2026 edition includes 50K, 25K, 10K, and a Kids Trail Run.
For runners comparing local trail options, it fits alongside other trail races in Thunder Bay.
Course
All races start and finish at Kinsmen Park (Trowbridge) off Trowbridge Road in Thunder Bay. The 25K is a single-loop course with two short out-and-back sections, using mostly singletrack with some doubletrack through Shuniah Mines trails, Cascades Conservation Area, Centennial Park, and parts of Trowbridge Park. The 25K includes about 370m of climbing. The 10K is a single loop through Shuniah Mines and back, and the 50K follows the same route twice. On-course aid stations and a water station between aid stations are part of the setup.
