The off-road trail race through the Val Casternone mountains, just outside Turin
The Val della Torre Alpine Marathon is one of the most beloved events in the Piedmontese trail running calendar. It takes place in the municipality of Val della Torre, in the Metropolitan City of Turin, right at the gates of the regional capital: a small village nestled in the Val Casternone, from which trails climb rapidly toward the ridges dividing the Susa Valley, the Viù Valley, and the Turin plains.
The event offers three tracks designed for different levels of preparation:
The charm of the race lies in its mountain amphitheater: runners traverse the valley's rural landscape, pass by historical sites like the Colle del Lys with its Resistance Museum and the Madonna della Bassa sanctuary, and follow a technical track that requires trained legs and sure footing. From the top, on clear days, the view sweeps across the entire Piedmontese plain.
Organized by A.P.D. Sportinsieme Val della Torre, the marathon has grown edition after edition, becoming a benchmark for trail runners in Piedmont. The organizational machine involves the municipal administration and numerous local volunteer groups—ANA, AIB, CAI, Red Cross, and the Pro Loco—who secure the trails, manage aid stations, and ensure safety along the entire route. The event is sponsored by the Metropolitan City of Turin and approved by FIDAL Piedmont.
The 16th edition of the Val della Torre Alpine Marathon was held on Sunday, April 12, 2026. The format with three tracks was confirmed: the 42 km marathon with 2,600 m of positive elevation gain, the 22 km half-marathon (1,550 m D+), and the 11 km non-competitive trail (350 m D+). The race, valid as a regional trail event, was approved by FIDAL Piedmont.
Routes: the marathon reaches Monte Arpone (1,601 m) and the ridge dividing Val Casternone, the Susa Valley, and the Viù Valley, with technical sections on scree; the half-marathon climbs up to Colle della Lunella (1,374 m). Registration via the wedosport.net platform, closing Friday, April 10, 2026, at 11:59 PM. The race was held in any weather condition.
Val della Torre is about 25 km from Turin. By car, take the Turin ring road, exit at Caselette/Alpignano, then follow signs for Val Casternone. The meeting point and start are at the local sports hall.
Competitors meet starting at 6:30 AM, briefing at 7:30 AM, with the marathon and half-marathon starting at 8:00 AM; the 11 km non-competitive trail starts at 9:30 AM (meeting from 8:00 AM). The race takes place in any weather condition.
This is a demanding alpine route with technical sections and scree: trail shoes, mandatory gear as per regulations, and adequate preparation are highly recommended. Aid stations are available along the route.
