Freddy Maertens (born 13 February 1952 in Nieuwpoort) is a Belgian former professional racing cyclist who was twice world road race champion. His career coincided with the best years of another Belgian rider, Eddy Merckx, and supporters and reporters were split over which was the better. Maertens' career swung between winning more than 50 races in a season to winning almost none and then back again. His life has been marked by debt and alcoholism. It took him more than two decades to pay a tax debt. He is now the curator of the Tour of Flanders museum in Oudenaarde.
