In the spring of 2021, as the UK's latest pandemic lockdowns were lifted, Nick Butter set out from the Eden Project to become the fastest person to cover ever mile of Britain's mainland coastline on foot. Battling the most extreme winds Britain had seen in 100 years, days of torrential rain and the unrelenting hills of Western Scotland and Cornwall, Nick suffered two broken bones and countless injuries, whilst taking on two marathons a day, every day, for 100 days.

Covering an extraordinary 5,250 miles, running for over 12 hours a day, struggling to take in the 8,000 daily calories required to fuel his body, Nick battled sleep deprivation and extreme weight loss as he pushed his body and mind to their limit.

Supported by close friends and family (including his ever-dependable right-hand man, Andy Swain, whose diary extracts feature in this book), Nick experienced spiralling lows and euphoric highs. As he traversed footpaths, country lanes and busy A roads, he passed through over two thousand coastal communities, buoyed along by supporters cheering from windows, balconies, passing cars and pavements, by school children and fellow runners, and by the stunning sights and sounds of the British coast.

Run Britain is Nick's account of his extraordinary adventure.
