Cornthwaite set out from John O'Groats on Sunday 30 April and took 34 days to complete his journey, which included four unscheduled rest days to recuperate from injury.

The skater arrived in Land's End to be greeted by a cheering crowd and was all smiles despite having skated a gruelling 895 miles through the British countryside.
Dave Cornthwaite said: "After all the sweat and blood I think I was too tired for tears at the finish line.
It's been an incredible, humbling journey, one I'll never forget. The British public has been amazing and I'd like to thank everyone who came out to support me."
The record-breaking skate is part of a project dubbed 'BoardFree', founded by Cornthwaite with the aim of raising £50,000 for three children's charities, Link Community Development, The Lowe Trust, and Sailability Australia.

However, reaching Land's End only marks the beginning of an epic journey for the skater, who only took up the sport last year.
In August, Cornthwaite will travel with a support team to Australia and attempt to break another world record by skating from Perth to Brisbane, a daunting distance of 4000 miles.
When asked about how the trips will compare Dave Cornthwaite said: "The UK journey was tough, but it is time for an even greater challenge and I'm looking forward to it."
