Penyagolosa Trails 2026 is one of Spain’s most iconic trail running events. On Saturday, 18 April 2026, Castellón province will once again host the classic MiM 60 km and the demanding CSP 106 km. The race connects the city of Castellón with the Sant Joan de Penyagolosa sanctuary and brings together thousands of runners, volunteers and fans from around the world. In this guide, you’ll find everything you need to know: history, course details, key athletes and practical training tips.
A race that connects Castellón with its most iconic peak
The MiM (Marató i Mitja) was established in 1999 as a 60-kilometre mountain race from Castellón to the Sant Joan de Penyagolosa sanctuary. Since then, it has become a benchmark in Spanish trail running. In 2012, the CSP was introduced: a 106 km ultra-distance race with 5,600 metres of elevation gain, following historic trails across the province.
Both races attract elite and amateur runners alike, and their success lies in the combination of tradition, physical challenge and spectacular landscapes. Local authorities highlight the event’s role in promoting Castellón internationally and boosting sports tourism.
MiM and CSP 2026 courses
The MiM 2026 stays true to its roots: 60 km with approximately 3,300 metres of elevation gain. The race starts at Jaume I University in Castellón and climbs through areas such as the Desierto de las Palmas and the forests of Xodos before reaching the iconic Sant Joan de Penyagolosa sanctuary at 1,280 metres above sea level. The route combines technical trails with more runnable sections, offering a diverse and memorable experience.
The CSP (Castelló – Sant Joan de Penyagolosa) is the more demanding distance: 106 km with 5,600 metres of elevation gain. It starts from Castellón’s bullring and crosses mountain areas such as Borriol, Vilafamés and Benafigos before joining the MiM course at kilometre 60. It is a true ultra trail race, with a strict 24-hour cut-off time.
Top contenders and international field
The 2026 edition will feature a highly competitive field. In the MiM, defending champion José Ángel Canales will face runners such as Marc Bernadès, Dakota Jones and Leonard Mitrica. In the women’s race, Inés Astrain will defend her title against athletes like Gemma Arenas and Azara García.
The CSP is also expected to feature strong international participation alongside local athletes aiming for the podium. The growing presence of runners from Europe and the Americas confirms Penyagolosa Trails as a key event on the global trail running calendar.
The volunteers: the backbone of the race
One of the foundations of the event is its team of around 800 volunteers, drawn from local clubs and associations. They are responsible for course marking, aid stations, checkpoints and runner support.
In addition, local communities along the route actively support the event, creating a unique atmosphere that reinforces its strong community spirit.
Sustainability and natural environment
Penyagolosa Trails is committed to environmental sustainability. The course runs through protected natural areas, and specific measures are implemented to minimise impact, including waste management and environmental awareness initiatives.
The race also highlights the region’s cultural heritage, passing historic buildings, rural landscapes and traditional paths that form part of Castellón’s identity.
Training tips for the MiM and CSP
Preparing for races with significant elevation gain requires a targeted approach. Incorporate hill training to build climbing strength and improve downhill technique, alongside muscular endurance work.
- Train for elevation: include long climbs and technical descents.
- Test your gear: use the same equipment you’ll race with.
- Practise nutrition: train your fuelling strategy during long runs.
- Pace your effort: consider power-based training to manage long climbs efficiently.
If this is your first time, start conservatively to save energy for the later stages. Proper tapering and adapting to weather conditions will also play a key role in performance.
