5. Marathon of Biarritz - Basque Country

The Marathon International de Biarritz – Pays Basque will take place on May 3, 2026, in Biarritz, France. In a spectacular landscape between the Atlantic, the coast, and historic Basque villages, participants will experience an urban as well as scenic running experience of the highest quality. The event began in 2020 as an idea of the Biarritz Olympique Omnisports and was first held in 2022 – with over 10,000 runners at the start ([marathonbiarritz.com](https://www.marathonbiarritz.com/evenement/historique/?utm_source=openai)). Since then, the marathon has seen increasing enthusiasm: in 2023, the number of participants grew significantly, especially in the 11-km format, and in 2024, a record of 12,000 runners was reached ([marathonbiarritz.com](https://www.marathonbiarritz.com/evenement/historique/?utm_source=openai)). In 2025, the fourth edition was celebrated – with an impressive 15,000 runners across all distances, a new record that underscores the event's great popularity ([mediabask.eus](https://www.mediabask.eus/eu/info_mbsk/20250505/marathon-de-biarritz-des-milliers-de-coureurs-au-rendez-vous?utm_source=openai)).
In 2025, ideal weather prevailed – sunny and pleasant – and the event quickly distributed starting spots: the 15,000 bibs were already sold out more than a month before the race ([presselib.com](https://presselib.com/article/marathon-biarritz-court-sport-coeur?utm_source=openai)). There was no lottery – the starting spots were allocated on a 'first come, first served' basis.
The course is technically demanding: the marathon includes around 480 m of positive elevation gain, making it one of the more challenging city marathons ([marathons.com](https://www.marathons.com/evenements/marathon-de-biarritz/?utm_source=openai)). The running routes lead through the heart of Biarritz, along the coast, through charming villages of the Pays Basque, and back to the Atlantic promenade, with the start and finish at Stade Aguiléra.
