Tre Cime di Lavaredo
In the winter of 2014/15, Steck and linked up the three north faces of the Tre Cime di Lavaredo/Drei Zinnen in 16 hours. In the summer of 2015, he climbed all 82 summits in the Alps higher than 4000 meters in 62 days without the use of motorized travel. Two days slower than the 60-day record, his time included a period when Steck had suspended the tour on July 22, after his climbing partner on the Aiguille de Rochefort, Martijn Seuren, had fallen to his death on this final peak to make him the first Dutch person to climb all 82 4000ers. Later that year Steck set a new record for the North Face of the Eiger, soloing it in 2 hours 22 minutes and 50 seconds.
