Overview:
This is a great race to start your triathlon or duathlon racing career or as a family adventure. The triathlon is in open water, but wet suits are not necessary as the water is a reasonable temperature. Distances for adults is Mini - 150 yds, Short - 300 yards, Long - 600 yards. The running course is mostly on a trail shaded with giant old growth Western Larch trees - 3 miles. The bike ride is on a combination of paved county road, dirt road and trails - 7.8 miles. All racers are chipped including the kids and finish times are immediately available for printing and on devices.

Registration: At the venue, Riverpoint Campground Day Use area, from 2-5pm on Friday and 7-8:45 on Saturday. T-shirts will be distributed for those registering before July 15 at these times. 

Everyone must park at Pyramid Mountain Lumber. There is no parking at the race site, and parking on Boy Scout or the neighbors driveways is not allowed. You may drop-off racers or spectators at the end of the road and they can walk or bike in and then park at Pyramid and either bike back to Riverpoint Campground or ride the shuttle.

We hope everyone stays for the awards ceremony where the winners stand on Olympic style boxes and get their medal. A great photo op moment.

Included in the racers fees are: parking, shuttle, T-shirt (if registered before July 15), race chip, snacks and medals for winners.

Spectators: FREE spectator parking and shuttle.  Please feel free to bring folding chairs. Spectators must STAY OUT of the transition area by using a trail from the spectator area at the finish line to the beach. 

Race Information: We have moved to a 3 second staggered start from the transition area starting at 9am. This has solved the congestion at the start of the race and since everyone is chipped there is no penalty for when you start. Everyone doing either the Triathlon or the Duathlon or participating as a team lines up by preference. All racers are chipped including the kids and finish times are immediately available for printing and on devices.

The Kids Triathlon starts when most of the adults have completed the course so families can watch approximately 11am. The kids use the outside of the swimming area bouys as their course. They can stop and hold on if they need to, and life vests are acceptable. Parents may follow along INSIDE the buoys. The bike ride is on the first half of the adult run trail for 8 and under and the entire adult run trail for 9-12.  The run is an out and back, to the campground road entrance for 8 and under and to the venue entrance for 9-12. They cross the same finish line as the adults.
