Mark Katz is based near Skipton in North Yorkshire, where he works full-time as a teacher. He climbed his first Font 8b in 2004 and still manages to maintain that standard. He has climbed in Europe, South Africa and the U.S but still loves the local gritstone edges of Yorkshire just as much as anywhere. Mark has developed new boulder problems in Yorkshire, the Peak, and North Wales, he has also repeated many of the U.K.'s best and hardest boulder problems and featured in the iconic bouldering film Stick It. Although nowadays Mark is somewhat of a ‘veteran’ on the bouldering scene he’s still as keen ever.
