Paralympian Sally Brown was born in Ballykelly and suffered from left arm dysmelia, which meant that her left arm didn't develop below the elbow.
Not one for letting her disability get in the way of achieving her goals, Sally's running talent was evident from an early age and she was quickly fast tracked into a GB training camp in 2010.
At just 15-years-of-age, she competed in the 2011 IPC World Championships in New Zealand and the 2012 Paralympics in London.
Now 18-years-old, she is ranked number one in the UK over both 100m and 200m distances.
Sally's father Richard says that her success is partly down to the support she received from the National Lottery.
"Lottery funding has helped Sally get to the level that she is at," he said.
"It has helped her with her travel costs so she has been able to get to competitions; with her coaching and with her physiotherapy.
"It has helped her get from being a top level athlete to a national level athlete where she is competing for her country.
"Sally has had a couple of injuries in the past year and if it wasn't for the national lottery she would not have been able to get the help she needed," he added.
"She was able to get top medical advice, to have the scans and fly over to England to get the top guys looking at her."
Sally hasn't been able to compete at any professional events this year due to injury.
She is now living in Loughborough where she is a full time athlete and studying part time.
She has also set her sights on preparing for the 2016 Olympics in Rio de Janeiro.
