Marimurumendi Marathon

The Marimurumendi Marathon takes place on 10 July 2027 in Beasain (Gipuzkoa). The event offers 42K (42 km), with start and finish in Beasain itself, and it sits on the trail calendar of pais-vasco.

The course

The route threads the paths, tracks and ridgelines around Beasain: wide gravel lanes, singletrack where the ground allows, and steady climbs that bite in the second half. It suits trail runners with solid base mileage; the shorter options work well as a first mountain race without committing to the long one. Start waves, cut-off times and aid stations are published on the organiser’s official website.

The 360 pack

Beyond registration, this page covers nearby accommodation, recommended gear, fuelling guidance, travel directions, car rental, race insurance and sun protection: your whole race plan in one place. Use the planner to fit the Marimurumendi Marathon into your season and browse more races in Basque Country to build a trip around Beasain.
