Hefin cycled the last of the 1000-odd miles this morning to complete the trip in 7 days, 50 minutes - 3 days less than most typical times - an outstanding effort for someone with relatively little experience on a bike. He travelled light, with just a rucksack and overcame punctures, thunderstorms and sunburned ears as well as an interesting trip over the Forth Road Bridge.
All funds raised from the challenge will go to Yorkhill Children's Foundation - an organisation that funds medical equipment, research, and treatment facilities at the Royal Hospital for Sick Children in Glasgow to help make a stay in hospital less distressing for kids and their families.
Congratulations to Hefin for completing such a huge challenge.
