Ultra Trails and Long Mountain Races in Spain 2026
Advanced races are designed for runners with solid mountain experience. We are talking about distances over 40 km, elevation gains exceeding 2,500 positive metres and terrain that includes technical passes, high-altitude zones and weather conditions that can change in minutes. At this level, preparation is comprehensive: periodised training, optimised nutrition, gear tested in detail and a well-defined race strategy. Cut-off times are tighter and aid stations more spread out. Spain has world-class advanced races, many of them with UTMB points and international recognition. If you have already mastered medium distances and want to raise the bar, these are the events that will truly test you.

Tips
Periodise your training: 12-16 weeks of specific preparation with volume, intensity and tapering blocks.
Know the course: study the profile, aid points and technical sections before race day.
Train in conditions similar to the race: altitude, terrain type, temperature and time of day (including night if applicable).
Have a plan B for nutrition: if your stomach rejects gels, you need proven alternatives like fruit, potato or broth.
