The first solo circumnavigation of the world by human power by Turkish-American engineer Erden Eruç.
In July 2007, Erden set out from Bodega Bay, north of San Francisco, aiming to become the first person to circumnavigate the planet solo, entirely under his own power—no motors, no sails, no means of propulsion other than his own strength. His plan was to travel across three oceans and six continents by boat, bike, and foot, more than 74 000 km or 40,000 miles in all, and climbing six of the seven summits, apart from Vinson Massif in Antarctica.
