Until he started training for the London Marathon in 2003 Mark had never run more than 3k without stopping. By April 2006 he had completed over 30 Marathons including Athens, Paris, Edinburgh and New York. He also began running ultra marathons completing 10 in one year finishing with the Marathon De Sables, a 250K self support run across the Sahara Desert.
One month later, Mark climbed Kilimanjaro in Africa, the first of his 7 summits and decided he wanted to climb the highest mountain in the world, Mount Everest in Asia, within 5 years.
The training took him to Aconcagua, Argentina in 2008 and Denali, Alaska in 2009. After a further years training in the Alps he successfully summited Everest in May 2011.
Early in 2012 friends living in the same French village as Mark suggested a ski tour to include Mount Elbrus, the highest mountain in Europe. A year to the day on from Everest, Mark and 3 friends stood on the top and he realised he had now climbed 5 of the 7 summits.
Mark decided that if he was going to complete them all it must be done straight away.
Travelling to West Papua, Indonesia in November 2012 he summited Carstensz and after a 2 week break he was off to the Antarctic to the final mountain, Vinson.
Standing on the top of Vinson on the 5th December 2012 Mark joined a very elite group of mountaineers that have successfully summited the 7 summits.
