Michael Doyle was born in 1950 and brought up in Newcastle upon Tyne. At the age of eighteen he joined the RAF and discovered climbing in 1969. He spent much of the next seven and a half years in the air force cragging and ticking off the great British classics such as Cenotaph Corner and Diagonal. During this period he took full advantage of the highly subsidised opportunity for expeditioning in the Alps and in such places as Kenya and South America.
Michael left the RAF in the late 1970s and got involved in the UK oil industry in the boom years. Marriage followed and soon after a move back to Wales in 1983 where climbing took a back seat for some years whilst children were being raised.
Around 1992 Michael rediscovered climbing, and particularly sport climbing, in a big way. Many trips to Portland, France, Spain, Kalymnos and Italy followed. The development of Penmaen Head between 2006 and 2008 instilled in him a taste for crag development, which Michael claims is possibly more addictive than climbing itself!
