Steeplechase runner Eilish McColgan is optimistic of recovering from a broken ankle in time for Rio 2016.
The 24-year-old Scot is missing from the World Championships as she recovers from the injury sustained in January.
"My main goal is Rio 2016," she told BBC Radio Scotland. "For me it still remains the main objective of the year.
"I'd love to be there competing for the team, but it's a little bit of a race against the clock now as to how quickly I can get myself back in shape."
McColgan competed at London 2012 in the 3000m steeplechase, failing to make the final, and came sixth in the same event at the 2014 Commonwealth Games in Glasgow.
But it has been a watching brief for McColgan during the World Championships in Beijing, where fellow Scot Laura Muir came fifth in the 1500m final on Tuesday.
"It's obviously frustrating watching it on TV when at the last World Championships in 2013, I ran a personal best, made the final and came 10th in the world," she explained.
"I started back walking this week, which was a huge step forward, so I'm hoping that in the next six weeks I can get back jogging.
"But very, very light jogging and just slowly build myself up for the summer season."
