A decade ago, Marcus Adam was preparing for the summer Olympics in Barcelona as the reigning Commonwealth 200m champion.
Ten years later, he is about to compete in his second Games - this time as a brakeman in the men's bobsleigh at the Winter Olympics.
It has been a stark change for the runner - not least the difference in temperatures - but Adam cannot wait.
He said: "To have been able to compete in the summer and the winter Olympics is fantastic."
The 33-year-old has not had the best preparation. He broke his toe earlier in the season which threatened his participation at Salt Lake City.
However, he is still in a positive frame of mind.
"Before Barcelona in 1992, I had had injury problems and was not fully fit going into the Games," said Adam.
"But I thrived on the pressure of performing in front of 85,000 people in the stadium and millions watching around the world.
"It worked because I made the Olympic final.
"It was a brilliant experience and it is something I want to repeat at Salt Lake City."
Adam will switch back to running once the Olympics are out of the way.
He is hoping to represent England in the 200m at the Commonwealth Games in Manchester in the summer.

Paul Attwood on the other hand will have to go back to work at his security firm Guardian Exec in Buckinghamshire.
The bronze medallist from the 1998 Games in Nagano has been given time off to compete - and is hoping to bring back another medal from Salt Lake.
He said: "The Olympics are the pinnacle of your career. You have to give it everything you've got.
"At Nagano, my event, the four-man bob, was on the last day of the Games and Britain had not won any medals.
"It was great when we won bronze right at the end. The euphoria was tremendous."
Dave McCalla is hoping he will become as much a household name as his cousin, England rugby great Jeremy Guscott.
McCalla, an RAF technician, has been bobsledding for seven years but this is his first trip to the Winter Olympics.
He said: "Jeremy called me when he knew I had been selected and wished me all the best and gave me a bit of advice.
"I am so excited to be involved in the Olympics and can't wait to get to Salt Lake City.
"We know with a bit of luck we could win a medal. We will give our all."
