Are you ready to "hang 10" on Lake Lanier?

The Surfrider Foundation Atlanta Chapter is inviting area athletes to bring out their inner surfer with a special event Saturday.

In celebration of International Surfing Day, the group is hosting the SUP Splash Lanier at the Lake Lanier Olympic venue.

The SUP (stand-up paddleboard) event will feature races, demonstrations and open-paddle opportunities.

The logistics of stand-up paddleboarding are pretty self-explanatory. Participants stand on a paddleboard, which looks similar to a surf board, and propel themselves through the water using a special, curved paddle.

Registration for the recreational two-mile race and the open two-mile race begins at 9 a.m. Saturday at the Olympic venue and costs $40 per participant. The local races are sanctioned by the World Paddle Association.

Free stand-up paddleboard demonstrations will be offered for children and adults, with Shane Webb conducting a free clinic.

For $30, attendees can sign up for a special 60-minute yoga class. The classes combine elements of paddleboarding with traditional yoga movements.

Proceeds from Saturday's event will benefit the surf organization and the Lanier Canoe and Kayak Club.

The Surfrider Foundation is a nonprofit that is "dedicated to the protection and enjoyment of our world's oceans, waves and beaches through a powerful activist network."

Event organizers will hold a 15-minute Hands Across the Sands demonstration beginning at noon on race day. Participants will create a human chain by standing in line, while holding hands on the beach. The purpose is to show visible support for the need to embrace clean energy.

Hands Across the Sands is a worldwide movement, where groups all over will form human chains for the same cause at the same time.
