No, the double Olympic Gold medalist from Jamaica who broke the 100m and 200m records this week does not trace his great-grandfather to Ballyvorney in County Cork, but the man who helped guide his career is agent Ricky Simms, who hails from County Donegal.

The 35-year-old has been Bolt’s agent for several years, and is a Director at Pace Sports management, a leading athlete management company in London.

In 2001 Simms was coaching athletes at the NCTC in Limerick (now known as the University of Limerick), and then moved to London to work at Kim McDonald’s athlete management agency in London. After McDonald’s sudden death that year, Simms and his partner Marion Steininger took over the company and renamed it to Pace Sports management.

Simms took up running in his youth and soon developed a passion for the sport.

"I ran for Finn Valley Athletic Club. I was the captain there for many years, I guess I was a good club runner in Ireland. Got a couple of Irish vests at under-23 level and student level but no championships like this," Simms told the BBC this week.  

That love for running eventually led him to coaching and now managing athletes. In Bolt, they represent the biggest star to hit the track in a long time. 

"He's a typical Jamaican, I think, very laid back, very, very laid back. In the warm up area before the 100 meters we were punching each other, rolling on the ground, he was laughing, he loves playing games. He's a young at heart kind of guy," continued the Donegal man.

"He's a happy guy, what you see on the track is real. When you see him serious you know that something is wrong.

"I think he takes all the credit, he's the athlete, he's the one that did it."
