Roger revealed he misses the buzz of competing and would love to get back on the track.
He said:
"I used to love it. I thrived on the pressure. It's pretty exciting when you do compete. I miss it in some ways. I used to love the whole anticipation."
Roger has been closely following the home nations’ athletic stars in the run up to the Games.
He said the pressure is on for SSE ambassador and Team Scotland poster girl Eilidh Child.

He said: "There's so much build up, there's much more pressure on Eilidh Child than there was in the Olympics. When she goes to other championships she is just another competitor, but she's everywhere here."
He also said he felt for Eilidh’s fellow SSE ambassador Katarina Johnson-Thompson after she was forced to pull out of the Games just days before the opening ceremony due to injury.
Roger said the decision not to come to will have been heartbreaking, but ultimately the best choice.
He said: "It will be hard for Katarina to miss it, but the right decision. It is really sad. This would have been her games. She's arguably better than Jess. If you're injured it's so hard. It's the hardest part of being an athlete."


Roger Black tells athletes: It's time to perform

Former Commonwealth 400m champion Roger Black has urged athletes to keep things simple and not to get distracted.
Roger won two gold medals in Edinburgh 1986 and was in Glasgow to lend his support to the home athletes preparing to hit the track later this week.
The Olympic silver medallist joined SSE customers and guests at a special event in the city where he offered some sage advice to competing athletes.
He said: "There's nothing they can do now, they can't train any more. There are a lot of distractions during the games so they will have to be as focused as possible."
