Lore & Trivia
Ultra Trail Monte Rosa runs around the Monte Rosa massif — the second-highest mountain in the Alps and the largest mountain mass. The course passes through the Aosta Valley, Valsesia, and the Walser settlements that preserve a German-speaking culture in the heart of the Italian Alps. UTMR is less famous than UTMB but equally dramatic, offering a more intimate mountain experience for runners who prefer Alpine beauty without Chamonix-level crowds.
- ▸ Mount Robson at 3954m is the highest peak in the Canadian Rockies — visible from much of the course.
- ▸ Berg Lake features actual icebergs calving from the Berg Glacier — a sight unique among trail races.
- ▸ The old-growth cedar forests along the Robson Valley are among the largest in the inland rainforest.
- ▸ Grizzly bears are common in the area — bear safety protocols are strictly enforced.
- ▸ Established in 2015.
UTMR is UTMB's Italian cousin — the Monte Rosa massif is just as dramatic as Mont Blanc, with a fraction of the crowds.
