Later books with fellow speedskater and medical doctor Asle T. Johansen have been of the "exotic group bicycling excursions" type, with emphasis also on the philosophy of travelling. These excursions have included bicycling around the earth in 80 days; the route of Mao's Long March; on the roof of the world in Tibet; and via the Andes to the source of Amazon River. Efskind's 2007 project is to lead a group of cyclists through the Vietnam War, from Hanoi via My Lai to the killing fields of Cambodia. Efskind has also been working as a medical doctor during the El Salvador civil war and in Palestine, while trying to pursue his talent as a painter.
