Which of Grosse Scheidegg, Susten or Croix de Coeur best represents the hit of The Ultimate 555 in its 2025 version? Your story will tell, and there's no doubt that the highlight will come from a mixture of emotions, luminosity and those first rays of sunlight piercing a ridge in the distance.

248km. It's after 248km that you'll experience that special feeling that only long-distance cycling can offer. After 248km, you'll have the Grosse Scheidegg at your back. In front of your wheel, the Susten. The majestic Susten and its 28km climb. The first ones will be there at dusk; the rest of the group at night.

At the tipping point, from first to last, it's the mind that takes over. Nourish your effort with the scenery you encounter, a good playlist and, for the lucky ones, exchanges with competitors you meet along the way.

After crossing the Valais, partly on its Left Bank, Le Château d'Aigle - the district's former prison - will paradoxically be a sign of liberation. Liberation both for muscles sore from the effort and, above all, for the multitude of emotions that will spring up when you dismount. Next stop, the finisher party!
