Archie Whitfield from Thirsk aims to run to 12 Scottish Premiership football stadiums in a week.
A football fan has begun a 250-mile (402km) run between all 12 Scottish Premiership club grounds in memory of his father, who died after suffering a brain tumour.
Archie Whitfield, 23, from Thirsk in North Yorkshire, set off from Aberdeen FC's Pittodrie Stadium on Saturday.
In April, as part of his bid to raise £100,000 for The Brain Charity, Mr Whitfield ran a total of 835 miles (1,344km), visiting each of the 20 English Premier League stadiums in 25 days.
Mr Whitfield, who aims to finish the challenge in Kilmarnock, said his dad would have thought he was "a bit bonkers" but would have been proud.
Mr Whitfield said he aimed to complete the challenge by the end of the week and with nine more grounds to go, he has already raised more than £23,000 for charity.
"My dad Dave was a massive part of my life," he said.
"I wanted to do something in his memory, because he was the sort of man who always tried to do something to make life for the people around him better, to make his community better."
He added: "Dad was a massive football fan, so it's fitting that I'm running between stadiums.
"He would have loved the fact it was football related. He'd be proud."
Mr Whitfield said he was excited about seeing the big stadiums "like Ibrox and Celtic" and even hoped to "get to see a few matches along the way".
