We were on the Frendo Spur, a 1200m Alpine classic on the North Face of the Aiguille du Midi in Chamonix. We’d climbed most of the route the day before and bivvied high to catch the final ice pitches in the coldest morning conditions. The strategy worked. We swapped climbing shoes for boots, crampons and ice tools, shouldered our packs and kept moving up.
Alpine grades are tricky to translate to UK grades because of changing conditions and route length. We estimated our conditions to be around HVS 4c on rock and Scottish Winter Grade III on ice and mixed sections.
Perfect conditions are rare. If the ice is good, the rock cracks tend to be iced up. If the rock is dry, the ice is often thin. We hit the sweet spot, with dry rock and good ice.
Our climb of the Frendo Spur was the high point of our Chamonix trip and the route we’d set our sights on. In the weeks before, we’d tackled classic mountaineering, ice and pure rock routes, but a forecast of storms made timing this climb a challenge. The stars aligned, and we completed the route in 28 hours. We’d have been faster if frozen lift cables hadn’t delayed our start.
