Trail del Jalón is a trail-running event in Benamira, in the province of Soria, and it sits inside the Soria Puro Oxígeno circuit run by the Diputación de Soria. The race day is built around short, accessible mountain distances: a 21 km trail, a 10 km trail, a 7 km hiking march, and a Trail Kids race for children.
The 21 km and 10 km trails are listed as non-competitive, and the hiking march is non-competitive too, so the event leans more toward participation than race rankings. That format makes it suitable for trail runners, walkers, families, and younger participants sharing the same local event rather than a single elite field.
