Tomorrow (Sunday) will see 32-year-old British endurance athlete Nick Butler – the man who set the world record for having completed a marathon in every country in the world – completing at the Eden Project his latest challenge: a record-breaking 5,250-mile run around Britain.

He is due to cross the finishing line on his epic two-marathons-a-day, 5,250-mile run around the coast of Britain at The Arena at the centre of the Eden Project, near St Blazey, at 4pm on Sunday. He started his challenge, again at Eden, on April 17.

Dorset-born Nick’s run is to raise awareness and funds for The 196 Foundation, a non-profit grant foundation championing democratic donorship.

The 196 Foundation says: “Our mission is to provide aid to the world in small bit-size chunks. The 196 Foundation helps one cause per year supporting those that need it the most – all over the world.” The causes could range from a wheelchair for a neighbour or building a school in Uganda, for example, and the Foundation asks people to sign up to give a regular donation of £1.96 a month..

Although endurance athlete Nick previously set a world record for running a marathon in every country in the world, he ranks this latest gruelling challenge as his toughest yet but is about to break another astonishing record - the fastest circumnavigation around the coast of Britain on foot.

He has achieved this despite numerous setbacks, including fracturing his shins, which resulted in a week’s postponement of the run while he recovered on crutches.

Nick says: “It turns out running two marathons a day isn’t just twice as hard as running one marathon a day… it’s far more brutal on the mind and body than I could have ever imagined. However, the incredibly kind and friendly support from fellow runners both in person and around the world has made it a little more bearable.

“Furthermore, the coast of Britain in all its natural beauty has blown me away. Everyone should see more of Britain - I’d recommend the whole coast! We live on a beautiful island. Let’s look after it.”

Nick has had more than 1,200 local runners join him at points throughout his challenge, who have all had an impact on the expedition, and he and his team hope that supporters will be at the finish line at Eden tomorrow to cheer him on as he completes his round the coastline challenge.
