Trail de la Côte de Lumière

The Trail de la Côte de Lumière is a 45-kilometre trail race with 600 metres of elevation gain, starting from Les Sables-d'Olonne, the famous Vendée seaside town known worldwide as the departure port for the Vendée Globe. This coastal event takes runners along the Atlantic coast of Vendée, nicknamed the "Côte de Lumière" (Coast of Light) for its exceptional sunshine, through a wild maritime landscape of dunes, cliffs, pine forests, and salt marshes.

Les Sables-d'Olonne, an elegant seaside resort whose remblai — the famous seafront promenade — faces a fine sand beach stretching over three kilometres, provides an iconic starting point. The town, intimately linked to the sea and sailing, pulses with the rhythm of the ocean. Runners set off from the harbour, the very spot where Vendée Globe skippers head out on their solo round-the-world voyages, before joining the coastal path that follows the côte sauvage — the preserved stretch of shoreline where schist and gneiss cliffs plunge into the Atlantic.

The Trail de la Côte de Lumière course alternates between spectacular coastal paths and the trails of the Vendée hinterland. The customs officers' path, carved into rock above the waves, offers grand panoramas over the ocean, wave-battered reefs, and inaccessible coves where sea spray creates ephemeral rainbows. Passages through the dunes, covered with marram grass and sand everlastings, demand particular effort on the soft sand. Maritime pine and holm oak forests lining the shore provide shaded, runnable sections, while crossings of the Guittière salt marshes or the Île d'Olonne lagoon reveal a landscape of geometric basins in which brackish waters shimmer.

With 600 metres of elevation gain over 45 kilometres, the Trail de la Côte de Lumière does not present the altitude challenges of mountain races, but coastal terrain imposes its own difficulties. The constant ascents and descents between cliffs and beaches, though modest in altitude, accumulate over the kilometres. Sand, headwinds on exposed sections, passages over wet rocks, and heat reflected from the shoreline make this race a more physically demanding challenge than its profile might suggest. The 45-kilometre distance also requires rigorous race management, particularly in the final kilometres when fatigue turns every dune climb into an ordeal.

The Côte de Lumière is a jewel of the French Atlantic coast, and this trail reveals all its wild beauty. Runners encounter remarkable biodiversity: little terns and ringed plovers nest on the beaches, egrets and elegant avocets frequent the salt marshes, while dolphins are sometimes visible from the clifftops. The Vendée light — that limpid clarity that gave the coast its name — bathes the course in a unique luminosity that magnifies the colours of ocean, sand, and sky. The Trail de la Côte de Lumière is an ode to the Atlantic shoreline, a race that marries physical effort with marine contemplation, carried by the offshore breeze and the inexhaustible energy of the ocean.
