Half Marathon races near Concarneau

Les foulées pluguffanaises is a 21 km trail race in Pluguffan, Finistère, Brittany, scheduled for November with the specific date to be confirmed.

The published route is 21 km with over 250 metres of elevation gain, indicating a rolling course rather than a flat, fast one. The listing does not include information on traditions, past winners, or participant numbers, suggesting it is a local Breton trail event offering a single short-trail race in Pluguffan.

Run à l'Orient begins next to the former submarine base at La Base in Lorient, a port city in Morbihan on France's Brittany coast. This early-March road race takes place by the sea, featuring city courses for adults and separate races for children and juniors. The primary distances offered are 5 km, 10 km, and a longer option described as either a half marathon or a 20 km urban trail, catering to both newer runners seeking a short goal and experienced runners wanting a more challenging course. The event is structured with several start waves: children run first, followed closely by the 10 km, 20 km, and 5 km races. The 10 km is a single loop, while the 5 km and 20 km formats offer relay options, making the event suitable for both teams and individual participants. The location is a key attraction: runners begin in Lorient's submarine-base area and follow a coastal city route, distinct from rural trails or stadium circuits. Bib collection is available on-site; organizers encourage participants to pick up their bibs on Saturday to avoid potentially longer waits on Sunday.

The Semi-Marathon Locronan-Plogonnec-Quimper is a road race held in March in Finistère, Brittany, offering two primary distances. The half marathon runs from Locronan through Plogonnec to Quimper, and a 10 km race goes from Le Croëzou to Quimper. These courses are designed for fast running, not arduous climbs; the half marathon has an elevation gain of 89 m and a loss of 239 m, while the 10 km gains 43 m and loses 129 m, featuring a 4 km downhill section. The half marathon is FFA certified, making it the sole certified half marathon in Finistère, allowing participants to qualify for the French championships. The course begins in a village designated as one of France's most beautiful, proceeds through the countryside of Plogonnec and Le Croëzou, and becomes more verdant and forested before concluding in Quimper, the capital of Cornouaille. The finish line is situated on the Odet quays, near Saint-Corentin Cathedral, placing the end of the race in the historic city center rather than a nondescript sports facility. The event attracts runners from all over France, with previous half marathon fields exceeding 2,000 participants and the 10 km drawing over 1,000. Additionally, free youth races for ages 7 to 15 are available, along with entertainment at the start and finish, and post-race crêpes.
