Olympic snowboarder Aimee Fuller announces retirement from competition
The two-time Olympian went to North Korea with Olympic Channel to run a marathon.
She wants to concentrate on media work instead.
"I'm still going to snowboard, but I can't snowboard at Olympic level and commentate, and do all of the other things I do,” she said to the Belfast Telegraph.
“The last two years since the Games (in Pyeongchang) have been amazing, but I can't keep up that pace outside my own sport.”
If there is something you love then go and chase it because it is there for the taking - Aimee Fuller to BBC
The 29-year-old isn’t going to stop snowboarding altogether – though it isn’t going to be the driving force of her life like it once was.
"I've had the most amazing career, one I never thought would be possible," she said to the BBC.
She competed in the slopestyle and big air events.
"I followed my dream and made a career out of it. If there is something you love then go and chase it because it is there for the taking."
Along with freestyle skier Mimi Jaeger, Fuller went to North Korea to run a marathon with Olympic Channel.
It was made possible through the efforts of the National Olympic Committee of the Democratic People’s Republic of Korea (DPRK) who helped the International Olympic Committee (IOC) give the film crew access to the country.
Fuller, who was competing in her first marathon, finished with a time of 4:35:34.
"(It was) one of the craziest experiences I think I've ever had. Going into the unknown for a week, being completely cut off from the outside world. Not only was it refreshing, it was eye opening," she said at the film's world premiere.
