David Walker, 69, had just completed the 5 km Parkrun in 21 minutes and was collecting his final token when he collapsed.
The Battersea Parkrun volunteer team quickly ran to help, and someone took the Parkrun defibrillator.
Dr. Stephen Murphy, an off -service doctor who had also made the race, was close and also offered assistance.
David, a former computer scientist at Cardiff, came to London from Cardiff that day to meet his daughter Katherine and participate in Parkrun.

He said: “I was waiting to collect my token and I felt dizzy.
“The next thing I remember was that I was on the floor waking up with many people standing around me.
“He had revived his leg after a defibrillator shock.”
The paramedics of the London ambulance service arrived in four minutes and Tok David to the San Thomas hospital, where he underwent surgery due to a implantable cardioverster defibrillator, a small device that corrects irregular heartbeat.
David’s daughter, Katherine, said: “He alarmed me when I picked up a call from my father and it was that the police tell me that I had a heart trial.
“I waited for the sausage when I got to & e, but I felt relieved to discover that I was awake and oriented.”

Last year, the ‘hikers’ in Battersea Park raised almost £ 25,000, enough to pay 15 defibrillators.
Mark Faulkner, paramedic consultant and associated clinical director in the London ambulance service, said: “It is incredible important that viewers begin the CPR and use a defibrillator as quickly as possible.
“These two things are really easy to do and more than double the possibilities of a person to survive a heart trial.”
David added: “I am very grateful to all those who were involved in saving my life.
“I don’t think I would be here without them.”
Dr. Stephen Murphy, a critical care doctor at Guy’s and St Thomas’ Nhs Foundation Trust, said: “I loved knowing that David has recovered completely.
“This type of event shows the impact that saves the life of early CPR and how can provide the best survival opportunity for anyone who has a heart trial.”
