La Plaine Mer Nature Run 2027

With the La Plaine Mer Nature Run, you’re coming for a real breath of fresh air between trails nature and the seaside, in La Plaine-sur-Mer, in Loire-Atlantique, where the sea spray gives you wings 🌊.

You choose your adventure: 8 km to enjoy yourself without rushing, 13 km for a nice complete loop, or 26 km to savor it for longer and come back with memories filling your calves (promise: the good kind) 🏃‍♂️.

And after the finish, don’t head home too fast: go digest it on the Customs Officers’ Path for a walk facing the ocean, push on to Pornic for a stroll around the harbor, or head to Préfailles for a sunset that’s worth all the medals 🌅.

If you’re coming as a pair or with family, you can also take a break on the beach of La Plaine-sur-Mer, grab a hot chocolate on a terrace, and tell each other about your race in “sea-mazing” mode! 😉
