Kirklanders can expect about 500 to 750 participants to be running, biking and swimming around Kirkland’s Juanita Beach Park for the city’s first TriFreaks triathlon in late September. The race will make Kirkland’s 10th triathlon overall.

TriFreaks Inc. has held races throughout Washington and was founded in 2004 with headquarters in Seattle. The company has supported Special Olympics Washington, The Rally Foundation, Young Life and more.

The event will be held Sunday morning Sept. 30, and athletes can take part in one of eight options ranging from a full relay team triathlon to a try-a-tri, a shorter triathlon, to a kid’s triathlon. The run course spans 3.11 miles and reaches Kiwanis Park, while the 2-lap 13.9 mile bike course stretches from Juanita beach to N.E. 145th Street and back around through Finn Hill. The swim course is a modest 0.5-mile loop.

“The race will be top notch,” said Leslie Barber, director of relations for TriFreaks Inc. “(TriFreaks) prides itself on good food, medals, vendors at the race with samples and fundraising for Hopelink.”

The triathlon will support Hopelink, a local nonprofit that provides social services to at-risk families and individuals in Washington.

Barber said a big truck will be available to drop off donated canned food or nonparishables for Hopelink. She said that one year when they had an indoor race they ended up with 700 pounds of food with only 200-300 people. Barber anticipates this year’s triathlon will bring in more.

Registration ranges from $105 for group relays to $55 for an individual child.

TriFreaks’ main sponsor is Kirkland-based Cobalt Mortgage, a company that provides financing to homebuyers. Cobalt Mortgage will provide finisher medals and T-shirts.

“Their president is a huge advocate for a healthy workplace and they have a really active community of employees,” Barber said.

Fifteen employees, including the president, will compete. Others will help volunteer on the course.

“We enjoy supporting community activities that promote positive choices, good health and personal achievement,” Cobalt President Keith Tibbles said.

Other sponsors include Lake Washington Physical Therapy, Clear Chiropractic, Sammamish Valley Cycle, Barleans organic oils and Erin’s Baker’s Breakfast Cookies.
