A teenager running a mile a day in April to raise money for a mental health charity will be joined on the final leg of the challenge by a man who ran the length of Africa.
Marcus, 16, is raising cash for Mind, in memory of a friend lost to suicide.
The avid Hull City supporter, known online as The Hull Boy, has more than 10,000 followers on YouTube and X, formerly Twitter.
The final mile will take place on 30 April in London, with Russ Cook - otherwise known as The Hardest Geezer - by his side.
