The Course des Etangs de Marignane begins at the Parc des Sports du Bolmon in Marignane, situated near the town's waters and natural surroundings. This local running and walking event offers multiple formats: walkers and participants with reduced mobility start first, followed by the 5 km race, and then the 10.5 km race. Over 400 runners and walkers are anticipated, with a program designed for various ages and fitness levels, not exclusively for fast club runners.
The course starts near the Bolmon sports park, following waterside paths close to the Balade des Familles. The longer race extends towards the Etang de Berre and goes through Parc des 4 Vents, providing a route closely connected to Marignane's lakeside environment. Children aged 6 to 12 have their own flat race on the athletics track at Bolmon stadium, with on-site registration. The Runners' Village includes a free smoothie stand for children and parents, and osteopaths are available to offer advice on healthy, safe sports practices.
