Sir Christopher Chataway, who died today aged 82, said running "returned to be a friendly codger" in his old age after acting as a tormentor in his younger days.
Speaking about taking part in the Great North Run at almost 80-years-old, Sir Christopher said at the time: "I sometimes think that running, which was a sort of tormentor in my youth, has returned to be a friendly codger in my old age - that what was Joe Stalin has turned into Dixon of Dock Green."
He is survived by his sons Mark, Matthew, Adam, Charles, Ben, his daughter Joanna, his wife Carola and his former wife Anna.
The son of athlete Sir Christopher Chataway, who died today aged 82, said his father continued running late in life and clocked up a "very respectable" time in the Great North Run three years ago.
He kept running almost until the end of his life. He ran with a couple of my brothers in the Great North Run about three years ago now.
And then doing it in a very respectable time.
Mr Chataway said he believed Sir Christopher would like to be remembered as "a wonderful father, a husband, a grandfather".
"Those probably mattered more than any of the sporting or political things," he said. Sir Christopher was also a Conservative politician and broadcaster.

The athlete's interest in keeping fit stayed with him as his life progressed and his son said that up until a couple of weeks ago he was on the exercise bike every morning.
Mr Chataway, 53, described his father as a "very compassionate and wise man" who had the "ability to put other people's needs first".
"We were, especially in these last few years, struck by his amazing qualities of humility and strength," he said.

The world's fastest man and Manchester United fan Usain Bolt has told ITV News that he is sure David Moyes "heard" his recent Instagram video message in which the sprinter said the Old Trafford boss needed to invest in his midfield.
"I was sitting at home and watching the game (against Liverpool) and I saw that in the midfield is where we are most weakest so I was just voicing my concern.
"I think David Moyes heard, I'm sure, because it was all over the news. I think he surely got that message. He got (Marouane) Fellaini (in) and (Shinji) Kagawa is now playing so the team is much better and a lot more stable."
