A cyclosportive, or often simply sportive, is a short to long distance, organised, mass-participation cycling event, typically held annually.
The already lengthy course will traditionally include climbs and difficult riding conditions, adding to the merit of the event (e.g. the cobblestones of the Paris–Roubaix).
This can encourage the fastest cyclists to push the pace, with faster riders working together to increase speed in a pro-peloton style.
Other notable events are the Cape Argus Cycle Tour in South Africa which celebrated its 30th year in 2007 with 40,000 entrants and Italy's Maratona dles Dolomites.
There are three UK cyclosportives held on closed roads: the annual Etape Caledonia which attracted some 3,500 cyclists in its 2009 edition, follows a route around the Perthshire highlands; the Etape Cymru, first held in October 2011 on North Wales roads including the Horseshoe Pass; and the Prudential RideLondon-Surrey 100 through central London and the Surrey countryside, which in its inaugural run in 2013 was completed by nearly 16,000 riders, and by over 20,000 the next year.
The Tour du Mont Blanc is a 330 kilometres (210 mi) long cyclosportive over mountainous terrain through France, Switzerland, and Italy.
Every second year there is also an 8 lap option, 1,280 kilometres (800 mi) long, but a following support vehicle is required for that version making it an ultracycling event.
