The Marseille-Cassis race is open to everyone and has a "silver label" classification from the International Association of Athletics Federations (IAAF), placing it among the top 50 running races in the world. Its official title used to be the Classique Internationale Marseille-Cassis.
In 2012, having shortened its route very slightly by 308 metres / 337 yards, it became the simpler Marseille-Cassis: 20 km / 12.75 miles. However it is still sometimes, inaccurately, referred to as a half-marathon.
The first race was held in 1979 and attracted 700 runners. Today, 15,000 runners take part from all over the world.
The date for the Marseille-Cassis race in 2013 was 27 October and the winner was Mulle Wasihum from Ethiopia who completed the course in one hour and eight seconds. The record remains with Kenya's Edwin Kipyego who completed the course in 2012 in 58 minutes and 16 seconds.
In 2013 the women's title was taken by Joséphine Jepkoech from Kenya, who completed the course in one hour, ten minutes and one second.
The starting point of the race is near the Vélodrome Stadium - home of Marseille's legendary football team Olympique de Marseille. Click on the map to enlarge the image.
The runners take a route through the Gineste pass (327 metres/1070 feet above sea level) and the plateau of Carpiagne.
While some runners might find the race to be on the short side, it also has long uphill and downhill stretches and is certainly no breeze. Participants pass through some of the most spectacular scenery in France and the road is closed to traffic during the race. Enthusiastic supporters guarantee abundant supplies of refreshments and a Tour de France-like party atmosphere all along the route.
Warm and pleasant but no longer sweltering, the weather in Provence is - if the fierce Mistral wind isn't blowing - ideal for running at this time of year.
Such is the popularity of the Marseille-Cassis that it has inspired another event, L'Autre Marseille-Cassis (The Other Marseille-Cassis).
This is a more leisurely ramble along much the same route the day before the race, designed to introduce participants to the beauty of the calanques and raise awareness of the environment.
Enrolment for the 2014 Marseille-Cassis race opens on 10 March at 9am for groups and 12 noon for individuals. And you are advised to move fast, very fast: the 2013 race was fully subscribed within an hour. Website for the Marseille-Cassis race
