When Sheffield's legendary fundraiserJohn Burkhill is asked, which one his countless charity races stands out the most, he has a simple answer: "They're all as special as each other," he says.
But ask him that question again next week and he might have a very different answer as the 'Man with a Pram' prepares for his 1,000th race having raised hundreds of thousands of pounds for Macmillan Cancer Support.
John, 79, whose wife June died of cancer, will take part in the Leeds 10K on Sunday as he closes in on his target of raising £1 million for the charity.
He said: "I wanted my 1,000th race to be in Sheffield but because of the bad weather a few races had to be rescheduled and it's turned out that it's in Leeds.
"But it's one of Jane Tomlinson's Run For All and she was a great friend of mine as his her husband Mike and I am very happy that I will be doing it there. They've asked me to take my Olympic torch too.
"I would have loved it to have been in Sheffield but I have got the comfort of it being for Jane and Mike. The public are always very welcoming in Leeds - just as they are in Sheffield."
Sheffield Wednesday fan John said he had so far raised around £750,000 and said he was 'determined' to carry on racing and walking around the city until he reaches the £1 million mark.
He said: "I never thought I would do 1,000 races and it will be special on Sunday but the races take me so long these days because everybody wants a picture or to donate."
John said he 'enjoyed every minute' of raising cash, in particular meeting people and hearing their stories of how Macmillan Cancer Support has helped them.
He added: "I would like to say a big thank you to both Sheffield Wednesday and Sheffield United supporters because I might be a Wednesdayite but I am as welcome at Bramall Lane as I am at Hillsborough - we are united in what we want to do and that is raising money for Macmillan."
