Longs Peak, The Diamond, First One-Day Winter Ascent. On January 15, Craig Luebben and I climbed the Diamond on Longs Peak in 20:40 from the parking lot. We chose D7 as it is the easiest aid line on the wall. We summited at sunset and the descent via the north face in the dark took five hours. This was the first time the wall had been climbed in the winter in less than 24 hours. In March, while training for the Survival of the Fittest Competition, Kennan Harvey soloed the same route and returned to the parking lot in 17 hours.
