La Bicentenaire brings together runners and walkers in La Roche-sur-Yon, Vendée, on an April weekend. The event features several races and hiking routes, attracting over 4,500 participants in total, with approximately 2,000 people starting the main Sunday race.
The course is set within the city, indicating a local, mass-participation event rather than a specialized trail or elite road race. Romain Bossis, the city’s mayor, participates and has done so since 2004. A recent edition was canceled due to budget constraints, and discussions have occurred about moving the race to a biennial schedule.
