Behobia–San Sebastián (20 km) 2027

The Behobia–San Sebastián isn’t a half marathon. It’s 20 km, a little over a kilometre shorter. But for many Spanish runners it’s the big road race of the autumn. The 61st edition is on Sunday 8 November 2026. It runs point to point from Behobia, the border district of Irun on the Bidasoa river, to the Alameda del Boulevard in the centre of San Sebastián. It’s organised by C.D. Fortuna K.E., and entries are sold out. The only way in now is the official waiting list or bib transfers through the organisers’ own platform. Never pay anyone outside it.

Three climbs

The course isn’t flat. The organisers’ training guide is built around its three hills: Gaintxurizketa, Capuchinos and Miracruz, the last one close to the finish in San Sebastián. Save something for the second half. In 2025 a course change made the race 20.2 km. Check the final 2026 course when it’s published.

Start groups by colour

Your bib colour decides your start zone, based on a time from the Behobia or a similar race in the last three years. For 2026 the fastest group needs under 1:12 for 20 km (men) or 1:25 (women), and the slowest is over 1:55. Colour changes closed on 20 September, and starting in a group ahead of yours means disqualification.

Last year’s schedule: wheelchairs and handbikes at 9:30, inline skaters at 9:35, elite women at 9:55, and everyone else at 10:00 in waves.
