BONNET AND ALEXANDERSSON SET RECORDS AT THE 2026 MARATHON DU MONT-BLANC

Rémi Bonnet of Switzerland won the 42K in Chamonix in 3:33:14 on June 28, setting a course record. Tove Alexandersson of Sweden won the women's race in 3:55:07 and became the first woman to finish the course in under four hours.

The Marathon du Mont-Blanc climbs 2,540 meters over its 42 kilometers, starting in the center of Chamonix at 6:45 a.m. and finishing on the mountainside above the valley. The race grew out of the Cross du Mont-Blanc, first run in 1979, and now anchors a four-day festival of racing in the valley.

Heat had settled into the valley before the start and stayed there for most of the field.

The Men's Race

Bonnet and Frédéric Tranchand of France ran at the front together through the opening half. Bonnet took the lead leaving Vallorcine and pushed the gap open on the long climb toward Flégère, the last sustained ascent on the course.

Tranchand is a strong descender and had the final drop into Chamonix to work with. The gap held, and he finished second. Manuel Merillas of Spain was third.

Bonnet's 3:33:14 lowered the course record. The Salomon athlete has built his reputation on uphill speed, and the climbing profile of the 42K suited him. He won the race once before, in 2023.

The Women's Race

Alexandersson's 3:55:07 made her the first woman to cover the course in under four hours, and lowered the women's course record for the 42K.

Ida Amelie Robsahm of Norway finished second and Naomi Lang of Britain third.

Alexandersson is a multiple world champion in orienteering who has moved into mountain running with immediate results. The 42K was her first win at Chamonix.

What Comes Next

The 2027 dates for the Chamonix weekend have not yet been announced. The event traditionally returns in the final week of June, with the 42K closing the program on Sunday.
