A former cancer sufferer from Scotland has undertaken four half-marathons in the space of 24 hours for charity.
Findlay Young will finish his feat with the Bupa Great North Run
Findlay Young, 30, originally from Castle Douglas in Dumfries and Galloway, was running 13.1 miles in all four UK countries.
He was due to finish at the Bupa Great North Run on Sunday - exactly a year to the day after he was told he had recovered from thyroid cancer.
Mr Young, who lives in London, plans to raise £10,000 for Cancer Research UK.
The management consultant began his challenge with a run in Belfast at 1330 BST on Saturday.
From there he was catching a flight to Prestwick Airport and travelling on to his hometown for his second race of the day in nearby Mossdale.
A car was then due to take him to Rhyl in Wales at about 0230 BST on Sunday to take part in the third leg of his programme.
Mr Young was then flying by helicopter to Newcastle for the Bupa Great North Run.
He was diagnosed with cancer in July 2003 after suffering problems with his thyroid gland.
After being given the all-clear his fundraising mission started with a commitment to do the Bupa Great North Run and grew from there.
Mr Young said: "I wanted to do an event in my hometown of Castle Douglas.
"Then the idea grew and I thought I'd add Northern Ireland and Wales as well.
"I see the Great North Run as my victory parade.
"I was determined to do it because of the date and I'll be running with number 2609.
"The event is an important milestone in my recovery from cancer and it's really given me something to aim for."
Former long-distance runner and Great North Run Chairman Brendan Foster said Young's 52.4-mile
challenge is an "incredible feat of endurance".
