As it's name suggests, the race starts in Paris (Eiffel Tower) and ends at Versailles (near the Chateau). It is only 16.3 km (10.1 miles) long, but a little hilly. This race owns its reputation to a friendly and folkloric atmosphere, with supporters and groups of musicians all along the way. Some people walk it just for fun of it.
