The Marathon Royan U Côte de Beauté runs the same coastal loop twice along the Gironde estuary, past the beaches of Royan, Vaux-sur-Mer and Saint-Georges-de-Didonne, and finishes on the sand of the Grande Conche. The course is flat and paved; what makes it hard is the second lap, when every rise on the corniche is already familiar.
The start is on Boulevard de la République facing Place Charles de Gaulle. The loop heads west first, past the Plage de Foncillon and the Palais des Congrès, along Pontaillac to a turnaround in Vaux-sur-Mer. It comes back right on the seafront by Saint-Sordelin and the Pigeonnier and Chay beaches, then follows the corniche past the Vallières lighthouse and along the Promenade Charles Martel to a turnaround just beyond the Relais de la Côte de Beauté in Saint-Georges-de-Didonne. The Grande Conche brings you back into Royan and onto the second, identical lap.
The climbing comes in many short waves where the road rises onto the cliffs above the coves and drops back; the high point is only a little over 20 metres. There is no long hill. With two turnarounds per lap you meet the field head-on several times.
The organiser calls it the race of eight beaches, and that is its character: the ocean and the estuary are in view almost the whole way, and apart from about 150 metres of finish matting on the beach it is all asphalt. Drinks come roughly every 5 kilometres, with misters and water ramps in between. The finish is on the Grande Plage, about 200 metres from the start.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
Plan the marathon as two equal halves and treat the first lap as a measurement: what does your heart rate do on the short corniche ramps at goal pace? The waves are short enough to run over at a slightly lower speed instead of holding pace and letting the effort spike.
The race is decided on the second lap, out to the Saint-Georges-de-Didonne turnaround and back along the Grande Conche. By then you are past 30 km, the field has thinned and the half marathoners who started alongside you have long finished. Runners who stay even here move up.
The usual trap is the shared morning with the half and the 10 km: the first lap feels easy in a fast crowd. Do not get pulled into their pace, and use the organiser's pacers as a reference. On an open coast the wind can also sit on one of the two arms; that is where running in a group pays.

For most runners the Royan marathon takes between three and a half and five hours. The effort is steady and aerobic, broken up by many short rises and drops that force small changes of rhythm but cost little as long as you do not run them at speed.
The decisive part is the second lap: after 25 km you still have to run what felt easy on the first. Build your long runs so that the final part is at marathon pace, and put them on rolling terrain where you can, so that short climbs at goal pace become routine.
Conditions in late May on the Atlantic coast are the second topic. The organiser sets up misters and water ramps between the aid stations, a sign that it can get warm, and the cliff-top sections offer little shelter. Do some long runs in the heat and practise drinking at aid stations about 5 km apart.
The focus is therefore pace resilience on rolling asphalt, marathon pace under fatigue and a fuelling routine that works when it is warm. There are several turnarounds: short brake-and-accelerate drills in your tempo runs help you lose less time at each one.
