It's touted as the longest-running stand-up paddleboard race in the world.

Quiksilver's Ta-Hoe Nalu Stand Up Paddle Festival, which has evolved from a modest race with 34 participants in 2007 to a three-day event with multiple races and hundreds of athletes, will take over the shores of Kings Beach this Friday through Sunday.

Aside from the 500-plus racers slated to compete, thousands of spectators are expected to attend the family-friendly event, which starts at 6:30 p.m. Friday with a concert on the beach by Mama's Cookin'.

A total of seven races will take place throughout the day Saturday and Sunday, as well as numerous demonstrations and clinics. The event includes distance and beginner races, sand castle building contests and more than $10,000 in cash and prizes.

Competition will include a 10-mile distance race, a 2-mile beginner race, a grom race, a four-person relay, a 4-mile open race and, of course, the elite finals on Sunday, which are expected to draw some of the best paddleboarders on the planet.

A world-record attempt for most people doing a yoga move on a stand-up paddleboard will also take place Saturday at 11 a.m.

A giveaway package at the festival includes a semi-custom "Wet Woody" paddleboard from Lakeshore Paddleboard Company named after the well-known drink from Gar Woods. The board is uniquely constructed with a hollow core and weighs only 22 pounds, according to organizers.
