    Description

    Today we crossed the spine of the Alps. Leaving Chamoson, we climbed steadily up the Rhône Valley before tackling the Col du Grand-Saint-Bernard. The legendary pass was relentless—winding, steep, and cold at the top, with patches of snow still clinging to the slopes. But the reward was immense: sweeping views and a thrilling descent into Italy. The landscape changed dramatically—sharper peaks, warmer air, and Italian villages clinging to the valley sides. We rolled into Aosta after 102 demanding kilometers, legs heavy but spirits soaring. Tonight, pasta and red wine. We’d crossed the Alps, and the Mediterranean felt closer now.
