A man who is running the entire length of the UK in a continuous relay with his brother admits the challenge is "a pretty brutal beast". Joe Pritchard, from Worcester, and sibling Alfie left John O'Groats six days ago and are due to arrive on Monday at Land's End, about 837 miles (1,497 km) away. Between them, they have been running 24 hours a day, with the goal being to raise £10,000 for veterans charity, Help for Heroes.
