That's exactly what the 30 sailors who've just left Les Sables d'Olonne in France are planning to do. They are taking part in the Vendee Globe, which runs every four years, and is described as "one of the most challenging tests of endurance there is".
You can find out more about the race here, where there are maps of the route, photos, video clips and weather reports, and information about the competitors, seven of whom are British. Find out more about them, their boats and their progress in the race on their websites: Mike Golding; Samantha Davies; Alex Thomson; Steve White; Jonny Malbon; Brian Thompson and Dee Caffari.
Rather them than me, I think!
