Island Peak is one of the handful of glaciated "trekking peaks" in the Khumbu. At 6189m / 20,305 ft, Imja Tse is a serious glaciated, high-altitude climb. The standard route has climbers heading from Chukkung to Base Camp and then usually summiting the following day. This FKT runs all the way from Chukkung to the summit (and back) in one fell swoop, though one could argue for a BC-Summit record as well if this route becomes more competitive.
