Easy shoreline swim starting at South Beach at Lake Lanier Islands and finishing at East Beach, sounds far, however it is only 1/4 mile and you can stand up the ent......ire way. If you need to take a rest or just want to make sure there is sand under your feet. The bike and run segments take athletes on a tour of Lake Lanier Islands and the surrounding community. Swim Course - Swim ¼ mile in Lake Lanier adjacent to the water park, athletes who feel tired or nervous can swim along the shore in waist deep water enabling them to stand up and take a break during the swim. Bike Course - Bike 12 miles total out and back from Lake Lanier Islands exiting and entering via the main road on and off the Island.
