Race Details
​
The UpRiver Running Fall Races hold a special place in our heart. This community event celebrates our love for the sport and unites participants from all walks of life with varying goals and experiences. The 10Km, 25Km, and 50Km distances offer something for everyone. In 2024, we also added a Kids Trail Race of about 2.5Km, as well as changed the start location to Kinsmen Park (Trowbridge).
This year, we'll also be providing a free vegetarian chili for all registered participants! Most of the course takes place on single track through some of our favourite trails in Thunder Bay. Participants will receive a finisher medal and the first finisher from each age division in the 10K, 25K & 50K events will receive an award.
