Grey-Thompson won 16 medals from five Paralympics

Dame Tanni Grey-Thompson admitted she was relieved to have ended her career after her last-ever race at a wet Manchester Regional Arena track.

Britain's most successful Paralympian signed off with silver in the T53 200m at the Visa Paralympic World Cup.

"I can't stop smiling now but it has been an emotional day for me," she told BBC Sport afterwards.

"I've got a real sense of relief and I'm happy I will never have to compete in these sort of conditions again."

Tanni was beaten into second place by American Jessica Galli, but was still delighted with the reception she received from the spectators at the track.

There is not an ounce of me that wants to do it any more and it's nice to feel that it's truly over Dame Tanni Grey-Thompson

"It was important for me to finish my career on home soil and the support I had was fantastic from the crowd and also from the rest of the team," she said.

"When I got to go back around the track after the race I realised how good the support from the crowd was, especially given the weather.

"As for the race, my start and pick-up were OK but I just couldn't get going after that. There's lots of reasons for that, partly my feelings and partly the conditions.

"But there is not an ounce of me that wants to do it any more and it's nice to feel that it's truly over."

The 37-year-old, who has won 11 Paralympic gold medals, is keen to stay active after her retirement.

"I might not be competing any more but I definitely want to stay fit," she added.
