The UpRiver Running Fall Races, scheduled for October 03, 2026, promise an unforgettable experience for runners of all levels. This community-driven event celebrates the joy and camaraderie found on the trails of Thunder Bay with a variety of distances: 10Km, 25Km, and 50Km races. The heart of the race lies in Kinsmen Park off Trowbridge Road, where participants will embark on courses that showcase some of the most beloved trail systems around Thunder Bay. The shorter 10K course offers a single loop through scenic Shuniah Mines trails before returning to the park. For those seeking more adventure, the 25K race takes runners on mostly single-track paths with brief out-and-back sections weaving through Shuniah Mines and Cascades Conservation Area. The full marathon of trail running is reserved for the 50K distance, which doubles up two loops of the 25K course. This technical route features a mix of rolling terrain and elevation changes that challenge even seasoned runners. Aid stations are strategically placed at Balsam Access Trail Head, Cascades Conservation Area, and Kinsmen Park to ensure participants stay fueled throughout their journey. Participants will find themselves surrounded by nature's splendor as they navigate the rugged yet rewarding trails. The race atmosphere is vibrant with a strong sense of community support from fellow runners and local volunteers. Upon crossing the finish line at Kinsmen Park, all racers receive a commemorative medal, while top finishers in various age categories are awarded special recognition. For families looking to join in on the fun, there's also a Kids Trail Run for those aged 17 & under, offering a kid-friendly 2.5Km route through Prospector Skills Trail and parts of Yellow and Red Trails within Kinsmen Park. To enhance your race day experience, optional vegan-friendly burritos are available for purchase at the event (orders must be placed by September 20th). Additionally, participants can opt to order a custom t-shirt via the ultrasignup "STORE" tab. Remember that this is a cupless event; please bring your own reusable cups or hydration devices. Registration fees vary based on early bird and standard entry periods, with late registration available until August 25th. Race bibs are transferable up to September 18th at 11:59pm.
