Penyagolosa Trails
CSP – Castelló-Penyagolosa
Castelló de la Plana → Sant Joan de Penyagolosa (Vistabella del Maestrat)
Race guide
Updated 19 July 2026
The CSP – Castelló-Penyagolosa is the flagship race of the Penyagolosa Trails festival, a 108 km point-to-point journey that begins at sea level in Castelló de la Plana and climbs progressively inland to finish at the ancient hermitage of Sant Joan de Penyagolosa at 1280 m. With 5079 m of total ascent and a high point of 1530 m, it is one of the defining long-distance trail races on the Iberian peninsula, following a route steeped in centuries of pilgrimage tradition through the interior of the Valencian Community. The race moves through a striking sequence of landscapes — coastal plains, medieval hilltop villages, deep ravines, pine forests and the high limestone massif of Penyagolosa itself — connecting nine checkpoints over roughly 108 km. There is a hard cut-off at the finish in Sant Joan de Penyagolosa at midnight on Sunday, so time management is as important as fitness on a course that gets progressively harder in its second half.
Course & Terrain Overview
The route leaves Castelló de la Plana (66 m) and immediately begins to climb away from the Mediterranean coast toward Borriol at km 12 (549 m), the first significant elevation gain of the day. From there, the course dips back down to the hilltop village of Vilafamés at km 26 (204 m) — do not be lulled by this lower elevation; the terrain between checkpoints is rarely flat, and the cumulative gain adds up fast. Les Useres at km 41 (407 m) marks the transition into true inland Maestrat country, where the paths become more technical and exposed. Beyond Atzeneta del Maestrat at km 53 (468 m) and Culla at km 67 (751 m), the character of the race changes decisively. The trails are rougher, the climbs longer, and the altitude increasingly felt at night when temperatures drop sharply. Benafigos at km 78 sits at 1165 m, Vistabella del Maestrat at km 93 at 1083 m, and the finish at Sant Joan de Penyagolosa at 1280 m — meaning the final third of the race is conducted almost entirely above 1000 m on technical mountain terrain.
Decisive Climbs & Where the Race Is Won or Lost
The back half of the CSP is where ambitions are either confirmed or unravelled. The climb into Benafigos (km 78, 1165 m) following the long approach through Culla at 751 m is the first truly mountain-scale effort, and it comes deep in the night when glycogen stores are compromised and mental resolve is tested hardest. Many runners who overextended in the first 50 km arrive here unable to sustain any meaningful pace. The final push from Vistabella del Maestrat (km 93, 1083 m) to the summit zone and the finish at Sant Joan de Penyagolosa (km 108, 1280 m) is the race's defining passage. The high point of 1530 m sits between these two points, and the descent from it onto the finish is technical and unforgiving on destroyed quads. Runners chasing the cut-off must leave Vistabella with enough time and enough leg strength to cover 15 km of mountain terrain — underestimating this section is the most common reason for late DNFs.
Pacing & Race Strategy
The profile of the CSP demands conservative early pacing. The first 53 km to Atzeneta del Maestrat should be run well within your aerobic ceiling — these kilometres are comparatively accessible, crew-supported at every checkpoint, and dangerously easy to overrun in good conditions. Banking time here by pushing hard is a false economy; the altitude, accumulated gain and night running in the back 55 km will always collect the debt. That said, race context matters. If you are competing in a team or championship format where only a high placing counts, an aggressive gamble is the correct and legitimate choice even if it unravels — a top-ten finish attempt that blows up is more honest to the format than a conservative jog to the line. For the vast majority of CSP runners, however, the objective is to arrive at Culla (km 67) feeling controlled, Benafigos (km 78) feeling capable, and Vistabella (km 93) with enough in reserve to climb to the high point and descend to the hermitage before midnight.
Fuelling & Crew Access
The CSP is generously crewed along its length, with accessible crew points at Castelló (start), Borriol (km 12), Vilafamés (km 26), Les Useres (km 41), Atzeneta del Maestrat (km 53), Culla (km 67), Vistabella del Maestrat (km 93) and the finish. Benafigos at km 78 is a checkpoint without crew access, so bags and drop bags must be planned accordingly — this is the one section where you are entirely on what you carry. Given the progressive climb in altitude and the likelihood of racing through the night above 1000 m, fuelling strategy must account for reduced appetite at altitude and the caloric demands of cold-weather running. Prioritise savoury, easily digestible foods from Culla onward, and ensure your mandatory kit includes sufficient insulation for temperatures that can drop sharply above Vistabella even in spring race conditions. Hydration sources are available at checkpoints but the mountain terrain between Benafigos and the finish demands self-sufficiency.
Conditions to Expect
The CSP takes place in spring across a dramatic elevation range — from 66 m at the Mediterranean coast to 1530 m on the Penyagolosa massif — and conditions can vary enormously within a single race. The early kilometres from Castelló through Vilafamés and Les Useres are typically warm and runnable, potentially hot in afternoon sunlight on exposed hillsides. As you climb into the Maestrat above 700 m, temperatures fall and wind exposure increases significantly. Above Benafigos and into Vistabella del Maestrat, night temperatures commonly approach or drop below 5°C in spring, and the high point at 1530 m can be significantly colder with wind chill. Rain, low cloud and reduced visibility on the summit section are genuine possibilities. Come prepared for a full alpine-night scenario in the final 30 km regardless of how pleasant conditions feel at the start in Castelló — the mountain has its own weather, and the cut-off at Sant Joan de Penyagolosa does not move.
