At the age of 12, Mark read about a cycle from John O’Groats to Lands End in a local newspaper, inspiring him to go on an expedition and that year he cycled across Scotland - from Dundee to Oban. Fast forward almost 20 years later and Mark has broken a world record for cycling the world, cycled the Americas and rowed the Arctic.

Now a broadcaster and adventurer, Mark is embarking on his latest expedition; following the as it travels through all 70 nations and territories of the Commonwealth.

In 2008, Mark Beaumont cycled around the world and broke the Guinness World Record for the fastest circumnavigation by bicycle. Mark cycled 18,296 miles in 194 days and 17 hours. His journey was documented in a Â鶹¹ÙÍøÊ×Ò³Èë¿Ú One’s four-part series, ‘' which was predominantly self-filmed by Mark.

His next big challenge came in 2009 when he cycled the Americas, taking him from Anchorage in Alaska to Tierra del Fuego, Argentina, also climbing the high peaks of Denali (Mount McKinley - 6,196m) and Aconcagua (6962m). (, Â鶹¹ÙÍøÊ×Ò³Èë¿Ú One)

Mark’s expeditions have not just been on dry land. In 2011 Mark was a crew-member aboard a rowing boat that travelled across the arctic. They became the first team to reach a certified polar position by rowing boat, the 1996 North Magnetic Pole. (, Â鶹¹ÙÍøÊ×Ò³Èë¿Ú One)

In 2012, Mark had a very different rowing experience when he joined a crew, made up of two triple scull teams, to attempt the World Record for the fastest crossing of the mid Atlantic by ocean rowing boat. But on day 28 disaster struck when a wave capsized one of the boat, and the crew, including Mark, faced the fight of their lives. The crew spent 14 hours in the water until a vessel managed to reach them and complete a dangerous night-time rescue.

Mark is currently making his way around the 70 nations and territories of the Commonwealth, as he follows the in the lead-up to Commonwealth Games 2014 in the host city Glasgow.
