Jonathan Siegrist

Jonathan Siegrist is an American rock climber, born on 27 August 1985, regarded as one of the world's most prolific sport climbers, with first free ascents and redpoints of a large number of routes at and above the grade of 9a (5.14d). He began climbing early with his father Bob Siegrist, an established 5.13 climber, but only started climbing seriously around 2004, at age 18. Climbing Magazine gave him its Golden Piton Award in the Breakaway Success category in 2009. In 2014 he climbed his first 9a+ route, Realization/Biographie, and he later became the fifth person to complete the 9a+ Trilogy. In 2018 he made the second repeat of Chris Sharma's Jumbo Love, his first 9b route, and in 2022 he made the first ascent of the 9b route Event Horizon in Las Vegas. Although best known as a sport climber, he has repeated some of the hardest traditional routes in the world, including The Path in Canada and Direct Dunn-Westbay on the Diamond in Colorado.
