A man who said he does not like running that much has just completed his 115th marathon with a personal best time.
John Krause, 54, started running marathons 15 years ago as part of a mid-life crisis aged 40, he said.
From last year: Marathon man completes century of runs
But since then he has not been able to stop and now runs the 26.2 miles every three weeks all over the world.
He is one of many runners from Merton to take to the streets of London on Sunday and help raise millions of pounds for charities all over the country.
From last week: Merton's marathon runners will take to London's streets next weekend
In the past few years Mr Krause has raised more than £8,000 for Stem4, a young person’s mental health charity set up by his wife Dr Nihara Krause four years ago after the death of their daughter’s school friend Anna Wood from anorexia.
Speaking about the London marathon, Mr Krause, of Montana Road, Wimbledon, said: "It is a great event, we do it so well in this country.
"I don’t like running that much, I did it because I was told I could play football better."
The marathon man completed the Virgin London Marathon in three hours eight minutes - his personal best.
Four years ago in Malta, he ran his previous personal best, which was three hours eleven minutes.
"It shows what you can do with commitment and motivation.
"I never thought I would have done this many when I started out," the father-of-four added.
Branching out into endurance tests, Mr Krause has signed up for an Ironman triathlon in September, where competitors must swim, cycle and run against the clock.
He will also take on the 100mile London to Surrey bike ride after completing his 116th marathon in St Petersburg in June.
As well as running, he swims, plays football and still finds time to run his own company - Diespeker Marble and Terrazzo, based in south east London.
Among those to join him at the finishing line on Sunday was Alice Sillett, pictured above, duty manager at the New Wimbledon Theatre, who has so far raised £10,000 for Leukaemia & Lymphoma Research.
She completed the event in five hours 27 minutes in memory of her mother Karen Sillett, who died within weeks of being diagnosed with acute myeloid leukaemia in April last year.
She said: "It was a brilliant day but there was some really tough moments.
"It was painful from the half marathon point until around 20 miles. My legs were aching and tired but you have got this amazing support with people cheering you on."

Kate Flory, 29, from Wimbledon, is raising thousands of pounds for the Animal Health Trust (AHT) through a series of personal challenges including the marathon.
She ran the marathon in five hours and 53 minutes and has already raised £1,470 for the charity in memory of her golden retriever Tia.
Speaking of the epic run, Miss Flory said: "One of the hardest but most rewarding experiences ever.
"I couldn't have done it without the incredible support of the London crowds, family and friends as well as knowing that it was all for an amazing charity, the AHT in memory of my dog Tia."

Ms Dunne, from Wimbledon Park, said: "It was an incredible experience all round. "Everything I have heard about the marathon supporters and how they carry you round was so true! Complete strangers calling your name and willing you through the pain barrier was truly amazing.
"I have the 'running bug' now and think Paris or New York may be next on the list."

Vanessa Cullip, above, took on the marathon to show her daughter Millie, who has cancer, that she can be brave too.
She completed it in six hours and one minute and said: "My marathon was everything I wanted it to be and more.
"The crowd were amazing and kept me going, as well as seeing my friends and family along the way. It was hard but totally worth it and for a great cause. Having Millie there to watch me was very special."
She has raised nearly £10,000 for Children with Cancer in aid of four year-old Millie who has Neuroblastoma.
