Ex-paratrooper Christian Lewis had hit rock bottom, suffering with depression so severe he would shut himself in his bedroom for weeks. Then while surfing – his sole respite – he cast his eyes along the coastline and realized it was the only place he really wanted to be.Then, Chris made an impulsive decision. He set himself a challenge: to walk the entire coastline of the UK. He gave himself a few days to rustle up a tent and walking boots, then left for good with just a tenner in his pocket and two days’ worth of food. Little did he know at the time just how long it would take to cross the finish line – and the encounters lying ahead would turn his life around....

After spending lockdown on a deserted Scottish island called Hildasay, it was time for Chris Lewis to complete his mission to walk the UK coastline. Then, in November 2020, he had an unlikely (seemingly destined) encounter with fellow adventurer Kate. The two turned out to be kindred spirits and – even more astonishingly – Kate made the bold decision to join Chris on the walk of a lifetime. Day in, day out, as they trekked the coastline down from Scotland together, their relationship grew, and soon the couple were thrown in at the deep end when their first child – baby Magnus – arrived.
