Rivers Edge Ultra returns to Spruce Grove, Alberta on September 19th for its second year as a major fixture in the local running calendar. The race begins at the picturesque Riverfront Park, located just off Main Street, near the confluence of the North Saskatchewan and Clearwater Rivers. The setting is serene; early morning mists linger over the waterways even by mid-September, providing a cool backdrop for participants as they line up on the starting line along the park’s well-maintained trail. Since its inception in 2025, Rivers Edge Ultra has grown from a local gathering to an event that attracts runners and ultra-distance enthusiasts from across Alberta. This year sees over 100 competitors participating in various distances, all pushing their limits on single-track trails known for their technical challenges yet breathtaking beauty. The cause behind the race is clear: every participant helps raise funds for Spruce Grove’s Youth Sports Scholarships, ensuring that local children have access to quality sports programs. The course spans a wide range of distances, from the shortest at 3km (Kids Muskrat Run) up through 12km (Half Yak), 50km (Muskeg), and all the way out to the extreme endurance tests of 80km (Wallace) or even an entire 100 miles. Each distance offers its own unique challenge, with the longer routes winding through dense forests, over rocky hills, and alongside meandering streams. Participants start at Riverfront Park and navigate a course that features significant elevation changes, ensuring no two kilometers are alike. Along the way, runners can expect to encounter several aid stations offering water, electrolyte drinks, and energy gels. For those venturing further, there will be pacers along the 100km Magilla route who provide support for those pushing their limits. Weather conditions on race day typically hover around a comfortable average temperature of 14 degrees Celsius (feels like 14C), with humidity levels at about 66.3%. The wind, averaging just under 11 km/hour, is mostly light enough to not be an issue but can offer some interesting navigational challenges on the longer routes.
