Run'n Sea is a small road running event on the seafront in Cagnes-sur-Mer, on the French Riviera. It offers two race choices, 5 km and 10 km, with an autumn slot in October and a deliberately limited field of 50 runners.
The route follows the Mediterranean shoreline, so runners spend the race beside the sea rather than in the hills or city streets. Ass Gazelles des Montagnes organizes the event, and the low entry fees and short distances make it easy for newer runners to join while still giving regular road, marathon, and trail runners a quick coastal race.
