Jim Holloway (born 1954), an American, was one of the first of a new generation of boulderers for whom the sport was a lifestyle rather than a recreation. He began bouldering in the early 1970s in Boulder, Colorado, and in 1973 established his first notable route, Just Right (so named because it fit his very tall frame). In 1975 he put up Trice (aka: AHR - Another Holloway Route) – at today's grade of V11 or V12, exceptionally difficult for the 1970s. In 1977, Holloway climbed Slapshot, on Dinosaur Mountain near Boulder. This challenge may very well be unrepeated as of 2006.
