The 24th Zegama-Aizkorri will be held on 25 May and pre-registration will open on 13 January for the marathon and 27 January for the KV and Junior Trail.

The Zegama-Aizkorri is taking shape on the horizon. The date has been set for the 24th edition of what is considered to be the most emblematic mountain marathon. It will take place on 25 May, when hundreds of fans will carry the runners through places that are already world landmarks such as the Sancti-Spiritu. The race breaks pre-registration records once again and for the 2025 edition there will be 225 places available.

Pre-registration for the coveted marathon bibs will open on 13 January at 12 noon via the Rockthesport.com registration platform. For ten days, from 13 to 24 January, everyone who wants to take part can pre-register for a bib for the marathon, while on 27 January the period for the Vertical Kilometre and the Junior Trail (16-18 years old) will open. The draw for the bib numbers for the three races will take place on 21 February.

On 25 May 2025, the athletes who will take over from the winners of the 2024 edition will be announced: Kilian Jornet, who took his eleventh victory in the race with a time of 3h38.07 (the second best time in the history of the race) and Norway's Sylvia Nordskar (4h29.12), who won her first marathon for the first time.
