‘Hardest Geezer’ reveals BIZARRE moment he began running as he shares how the sport changed his life after completing the London Marathon two weeks after his 10,000-mile challenge across Africa

‘Hardest Geezer’ Russ Cook completed the London Marathon on Sunday – just two weeks after completing his epic 10,000-mile run across the length of Africa.

And now the runner, 27, has opened up about where it all started as he revealed the bizarre moment he decided to take up the sport.

Appearing on Good Morning Britain with presenters Richard Madeley and Susanna Reid on Monday, Russ admitted it all started in a nightclub toilet.

The world record breaker started marathon running at the age of 20 after making the decision to turn his life around while struggling with a gambling addiction.

Richard explained: ‘It just happened, you were in a nightclub one night, you were a bit overweight, a bit hammered and you looked at yourself in the vanity mirror and thought, ‘This has got to stop.’

“And you ran home from the club, 11 miles at three in the morning.”

“Pretty much exactly that,” Russ confirmed, joking, “Yeah, lack of cabs that night or something.”

He then explained, “But yeah, I ran home, had a pretty hard time, took a few breaks and slept on the sidewalk, but then my buddy said to me, ‘Come on, do this half marathon, get into it .” I had nothing else to go for, so I thought I’d just give it a try.’

And the sport has completely changed Russ’ life, as he confessed that he struggled with gambling and had hard times before discovering his love for running.

Russ continued: “I struggled with gambling and that involved some pretty rough nights, but I discovered running and that was what I could focus my energy on.

“It’s given me some positive results for the first time in a long time.”

When asked what the star’s next challenge is, he teased: “I have a few ideas, but nothing is set in stone.”

Russ joined a record 50,000 people taking part in the London Marathon on Sunday as he completed the grueling 42.2 mile course in four hours, 25 minutes and 40 seconds.

Russ admitted it all started in a nightclub toilet when he realized he had to change his life and decided to run home - 18 miles - at 3am
