2 triathlon events in Maple Valley, Washington

Join us for one of the top early premiere triathlons in the region. Get an edge on your triathlete competitors by performing well in this super sprint triathlon. You start off with a quarter-mile swim in Lake Wilderness, typically the first week in May is in the 80s but the water is still a chilly 60F (wetsuits are allowed and encouraged). Next you start your 14-mile trek on 3 miles of road/asphalt followed by a hard packed dirt/limestone Cedar River trail. Slight downhill to the turnaround point which is also 2 miles of asphalt/bike path. Scenic views of the Cedar River as you speed across the trestle. This year we are eliminating the staircase and have a smooth transition onto the Cedar River Trail. All entrants get a super deluxe long sleeve mesh t-shirt, and all finishers get a forged Cedar River medallion. Apple, bananas, and oranges await you at the finish with festive Cedar River music. Photo finish - Smile ;).
