The Kettle Mettle Dirty Fondo follows the historic Kettle Valley Rail Trail through British Columbia’s Okanagan Valley, running from Penticton’s Lake Okanagan to East Kelowna. As Western Canada’s oldest gravel fondo and a Gran Fondo World Tour – Gravel Series event, it has built a reputation for combining challenging riding with spectacular scenery.

The course traces a decommissioned Canadian Pacific Railway line with a maximum 2.2% grade, making it more about endurance than steep climbing. The route passes through Myra Canyon Provincial Park, where riders navigate historic trestles and shaded railway tunnels while taking in panoramic views of crystal-clear lakes and wildflower-filled canyons. Three distance options accommodate different experience levels: the 50km Medio Fondo for beginners, the 100km Full Fondo for intermediate riders, and the 138km Full Fondo Plus for experienced cyclists. A two-day stage race option covers 112km from Princeton to Penticton, then 100km from Penticton to Kelowna.

The event attracts riders on everything from gravel and cyclocross bikes to mountain bikes and road bikes, though suspension isn’t necessary. Organizers recommend wider tires with lower pressure and disc brakes for the varied trail surface.

The finish line celebration includes a post-ride meal, local beer, commemorative t-shirt, wine, and raffle prizes. Both individual and team competitions are available, with teams of two or four members competing on combined finishing times. The relaxed atmosphere emphasizes the riding experience over pure competition, drawing participants across all fitness levels.
