Runner climbing to Monte Moro pass

Stage 4 – Macugnaga to Grächen

44.7 km with the promise of an exceptional mountain experience on the Monte Moro pass.

The final stage that completes the kora of Monte Rosa, and definitely a privilege to run this in daylight as a stage racer. You’ll be glad if your race strategy has kept some reserve energy for this stage.

Route summary

For runner Ruth Croft, this was her favourite stage. “It did start off with tired legs and a relentless, steep climb in the dark, but things quickly turned around with the epic sunrise on Monte Moro Pass,” she says. See the stage profile below, the climb is indeed relentless!

In the rifugio below the pass is an awesome aid-station where you most need it. Recharged, there is a technical descent into Switzerland with “views of the turquoise Mattmarksee, sitting between the massifs of Rimpfischhorn and Stellihorn,” remembers Croft.

After a long runnable section to Saas Fee, the day is only half over. The Höhenweg comes next – 20 km of unrelenting twisting and undulating trail. It’s the final challenge of this Bold, Brutal & Beautiful course.

Stage 4 highlights

  • Sunrise on the southern face of Monte Rosa from Passo Monte Moro. A glorious sight in clear weather.
  • Generous attention at the Monte Moro aid station, run by the On team.
  • The satisfying technical descent into Switzerland with views of the turquoise Mattmarksee.
  • Completing the challenge of the airy Höhenweg.
  • The smooth descent into Grächen where a warm welcome will await you.

On the pass…

Stage 4 was my favourite. And tough with tired legs. But the epic sunrise on Monte Moro Pass & views down to the turquoise Mattmarksee, it was one of those times where I had to stop running for a moment just to take it all in.
