1. Tybee River Race: 6 ½ miles on the tidal river separating Tybee and Little Tybee Islands; tests speed and endurance. 2. Little Tybee Challenge: 8 miles, circumnavigates part of Little Tybee Island, passing through narrow tidal creeks, broad tidal rivers, open coastal areas, and two surf zones. Little Tybee Challenge racers should have rough water experience and be competent at self rescue. Your boat must be sea worthy in rough conditions. 3. Race Across the River for Gold Sponsors: Our Gold sponsors compete for a grand prize of a two- hour natural history trip for ten-plus people on Mike Neal’s boat, the Island Explorer, or a kayak adventure for up to 8 with Moon River Kayak Tours. Each of these sponsors selects one person (employed by the business or part of the group) to race a kayak (we provide) across the Back River and back to the marina.
