A charity champion is pounding the streets - every single day - to help in the fight against cancer.
Mark Flint, 44, is running at least 5 kilometres every day of 2021.
And the unlikely springboard for Mark's gruelling challenge came in the shape of Manchester's landmark Beetham Tower.

Mark, from Cheadle Hulme, Stockport, has completed more than 260 runs so far - and vowed to keep on going through to New Year's Eve.
His runs have even included a number of longer challenges, like the Great North Run a week ago.
He will also tackle the London Marathon in two weeks' time.
Mark lost his uncle to cancer and his father was recently diagnosed.
He's raising money as he runs for The Christie cancer charity and remarkably, despite covering more than 1,500km so far - equal to 930 miles - he hasn't suffered a single injury bar a few blisters.
"It's for everybody who has been diagnosed with cancer," Mark said.
"It's helping them to have that quality of life."
Mark, who works in car insurance as a fraud investigator, started his exercise journey two years ago.
"I went through quite a bad divorce and I needed to lose weight, I was in a tough place mentally and physically," he said in an interview with the PA news agency.
"I was walking through Manchester city centre one day and there was an advert for The Christie to walk up the Hilton Beetham Tower.
"It was 68 flights of stairs and I just said, 'I'm going to do that'. It all started from there.
"It was a win-win for me getting the physical side and mental side, but also as a thank you to The Christie and what they did for [my uncle] to make his life as good as it could have been up until he ultimately passed away."
Mark decided to take on the daily challenge after being inspired by fellow runners on Instagram, where he posts his daily progress on his page runningmanflinty.
He said the running has helped his mental health and he's also lost two and a half stone in weight.
Despite his jogging, and 'at least 10' runs well beyond 5km, Mark said he has so far avoided any serious injuries, bar some blisters since the 21km Great North Run.
Asked what message he hopes his journey will give, he said: "I always say, if I can do it, anybody can do it.
"You don’t need expensive gear - just a pair of trainers, shorts and a T-shirt.
"It's free and you can see amazing places as well. You can explore and you can raise money."
Mark's partner, Caroline Wheeldon, was full of praise.
She said: "What Mark is doing is amazing and his determination is incredible. Finishing this journey on December 31 will be an incredible achievement."
