Jenny Meadows has said that she is desperate to represent Team GB at next year's Olympic Games in Rio de Janeirio.
The 34-year-old was due to compete in London three years ago, but she was ruled out of the home Games due to an Achilles injury.
The 800m runner has targeted a positive showing at the World Athletics Championships later this month to take forward to Brazil.
"In the three years leading up to London, I was ranked in the world's top three. I just really want to give it another shot," she told BBC Sport.
"I'm trying to make that World Championship final. That will give me a big spring in my step and a lot of confidence going forward to Rio."
In 2008, Meadows reached the semi-finals of the Olympics in Beijing.
