Maratón de las Tucas: high mountain terrain within the Aneto-Posets festival
The festival includes longer ultras and shorter races, so select Maratón de las Tucas when checking entry, kit and cutoff information for this distance. A date attached to the festival or to Gran Trail Aneto-Posets itself does not automatically identify the marathon’s start day.
The 2026 programme scheduled the marathon at 08:00 with a 22:00 finish closure. Those times describe the completed edition. A future participant must also check intermediate gates and any course changes rather than relying only on the overall allowance. Collection and equipment checks have their own deadlines before the start.
This is a mountain route, not a road marathon with a scenic backdrop. Long climbs, descending and sections above 2,000 metres change the expected effort and moving time. Prepare on comparable terrain where practical and use the final profile to identify the longest gaps between assistance. A road personal best is not a direct pacing guide for this course.
The rules use a semi-self-sufficient format. Carry the required supplies between aid points and inspect the complete equipment list for the intended edition, including weather protection. Test the loaded pack and navigation setup during preparation rather than assembling unfamiliar equipment on race morning. The mountain weather can differ from conditions in Benasque, so follow organizer updates and instructions if the course is modified. Supporters should use authorized access points and avoid assuming they can meet runners anywhere along a refuge path. Confirm baggage, collection and finish arrangements in the next participant guide before booking transport. The older route provides useful preparation context, but the next exact date, entry availability and operational timetable remain pending until the organizer publishes them.
