  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 ;).

  Event details and schedule

  Plenty of parking at the Lake Wilderness Park. There will be certified life guards in the water, and certified flaggers on the first time getting you through the intersection. Water, Gatorade, Gel, first aid on the course. AED and lifeguards are in the water for your safety- raise your hand if you can if you are having trouble. All bike handles must be plugged. Police and Search and Rescue have been notified. Brush off those running shoes and score your big finish this year at the 2026 Cedar River Tri!

  GIVING BACK TO THE COMMUNITY

  Proceeds from the Bear Run will benefit Tahoma High School distance running programs administered by the Tahoma Cross Country Running Club. The funds fill a wide range of needs for our large team of athletes including support for athletes and families who need help with team participation and summer camp fees, multiple scholarships awarded each year, and travel expenses beyond that available from the school district budget. These kids work hard and run hard all year while maintaining exceptional grade point averages. They deserve our support!
