Sand races

We’ll tell you straight: you’re going to be slow 🐌

Sand forgives nothing, and that’s exactly what draws runners looking for real sensations 🤪. Unlike asphalt—rigid and predictable—sand absorbs energy with every impact 💥. What makes this terrain so unique is its ability to multiply the effort without ever increasing the speed shown on the clock 😅. Moving on sand can require up to twice as much energy as on a stable surface, a figure that explains why so many athletes deliberately train on it to improve 🏖️. This sedimentary rock made up of fine grains born from erosion behaves differently depending on its moisture: compact and runnable near the water, but sneaky and exhausting once dry 😈. And depending on the ground texture, the sensations change 🔄. On wet sand, your stride stays crisp, almost as fast as on the road, carried by the sound of the waves and the salty air 🌊. On dry sand, on the other hand, every footstrike sinks in, the ankle twists, the calf starts burning in just a few minutes 🥵. The technical motion changes completely: the stride shortens, cadence climbs, arms work more to compensate for the instability. On a dune, the slope adds yet another difficulty: each step back almost as much as forward, a real patience game that only well-trained calves can tame without forcing it 😩.

Conditions vary hugely depending on the location📍. By the ocean, sea winds and tides set the rhythm: some races deliberately align with the tidal coefficient to benefit from firm, fast sand. In the desert, it’s a whole different story: crushing heat during the day, a brutal drop in temperatures at night, and sand that gets absolutely everywhere—including the best-sealed shoes 🏜️. A good pair of gaiters then becomes essential, as does precisely planned hydration to make the distance 💦.

In France, there’s no shortage of options to take on the joys of sand 🕺. In Normandy’s Manche department, the Enduro des Sables has participants run between Agon-Coutainville and Blainville-sur-Mer, over distances ranging from 7 km to the half marathon, with a good dose of Norman friendliness and costumes in the pack 🥳. In Vendée, the Triathlon Nature & Famille des Sables d'Olonne combines swimming, cycling, and running on Vendée’s beaches, in a setting designed for the whole family. In Brittany, the Triathlon Sables et Cap unfolds its routes between land and sea on the Dune of Fréhel, with a charity dimension benefiting the fight against multiple sclerosis 💛. Further southwest, in Lot-et-Garonne, the Course des Sables brings together the runners of Barbaste each year around a course known for its warm atmosphere 🫂. And for fans of mixed terrain, the Trail sable et forêt Patrick Fougère alternates woodland and beaches to vary the pleasures on the same course 🌳.

Internationally, one single event is enough to sum up the extreme end of the genre: the Marathon des Sables, nicknamed the toughest race in the world 🌍. Each year in early April, around 250 km are covered in six stages across the Moroccan desert, in complete food self-sufficiency, with a thermometer that climbs above 45°C during the day before dropping drastically at night when the sandman comes by 🌙. The course crosses the Errachidia region, between dunes and rocky plateaus, all the way to the finish near Ouarzazate, nicknamed the gateway to the desert 🐪. At the Marathon des Sables, the bivouac under the "khaïmas", traditional Berber tents, offers a rare moment of sharing, far from the freeze-dried meals you quickly forget when faced with a real tagine or a couscous enjoyed on your return 🍽️. On French beaches, the tradition is simpler but just as tasty: a good mussels and fries or a crêpe after the race, enjoyed with your feet still full of sand 🍹.

Running on sand means accepting starting from scratch with every stride, between raw effort and windswept landscapes 💇‍♀️. If the call of dunes and dry heat tempts you even more than beaches do, head for desert races, where sand takes on a whole other dimension, between vastness and TOTAL isolation ❌.
