The inspirational story of Britain's greatest paralympian.

In Seoul in 1988, Tanni Grey-Thompson represented Great Britain and won her first Paralympic medal - the 400m bronze. It was the beginning of an outstanding career leading to an astonishing sixteen medals - eleven of which are gold - countless European titles, six London Marathons and over thirty world records.

She was awarded an MBE in 1992, the OBE in 2000 and became Dame Commander of the Order of the British Empire in 2005. In 2010 Baroness Grey-Thompson was appointed to the House of Lords as a crossbench peer.
