KV Chiavenna-Lagùnc and Val Bregaglia Trail 2026: a weekend of mountain running between Italy and Switzerland
On 17 and 18 October 2026, Chiavenna will welcome some of the biggest names in trail running and mountain running, with two events that attract international athletes and running enthusiasts from across Europe every year:
the Kilometro Verticale Chiavenna-Lagùnc, now in its 27th edition, and the Val Bregaglia Trail, celebrating its 10th anniversary this year.
Two races, one unforgettable weekend dedicated to everyone who loves running along historic trails, mule tracks and spectacular mountain landscapes stretching between Valchiavenna and Switzerland.
Saturday 17 October: the KV Chiavenna-Lagunc, the “race of records”
The challenge starts at the Loreto church, at an altitude of 352 metres, and climbs all the way to the Lagunc mountain pasture, at 1,352 metres. The course covers 3.3 kilometres with 1,000 metres of elevation gain, entirely uphill, following mule tracks and natural mountain trails.
The route includes historic paths such as the Pianazzola mule track and is officially certified by FIDAL and World Athletics. Among mountain running specialists, it is known as the “race of records”: over the years, it has welcomed champions such as Marco De Gasperi, Jonathan Wyatt and Henri Aymonod, all taking on a time trial that pushes even the fittest athletes to their limits.
Born from the Trofeo Amici Madonna della Neve Lagùnc in 1986, the Kilometro Verticale has grown into one of the most prestigious events on the Italian and international mountain running calendar.
Sunday 18 October: the Val Bregaglia Trail, along smugglers’ trails and a new relay challenge
The following day, the action crosses the border. The Val Bregaglia Trail runs between Italy and Switzerland, following ancient paths once used by smugglers and winding through forests and spectacular landscapes connecting Promontogno and Chiavenna.
This year, runners can choose between two challenges:
the main 25 km trail, featuring 1,050 metres of elevation gain and 1,000 metres of descent, for those looking to take on the classic trail distance;
the Italian Mountain Running Relay Championships, a new feature for the 2026 edition, bringing Italy’s top mountain running teams to Chiavenna for a fast-paced and highly competitive race.
The Val Bregaglia Trail is part of the ITRA National League calendar, confirming its international appeal and the technical quality of its course.
Together, the two races, both organised by ASD Amici Madonna della Neve Lagunc, create a true mountain running festival, bringing elite athletes and amateur runners, families and trail running enthusiasts to Chiavenna.
Set between the peaks of Valchiavenna and the Swiss border, the area once again proves to be the perfect setting for outdoor sports, combining challenging mountain trails with spectacular natural scenery.
Whether you want to take on one of the most iconic uphill challenges in the Lombardy Alps or follow the historic border trails of the Val Bregaglia Trail, Chiavenna is waiting for you on 17 and 18 October 2026 for two days of sport, nature and challenges to be experienced right to the very last breath.
