Olympic torch: Diabetic Cardiff runner Melanie Stephenson
When the Olympic torch visits Cardiff on its first day in Wales on Friday, local girl Melanie Stephenson will be carrying it past Cardiff Castle.
The athlete, who has been capped for Wales, was diagnosed with Type 1 diabetes when she was 13, and took up athletics initially as a way to help control her condition.
She was nominated to carry the torch following years of voluntary work with the charity Diabetes UK.
She hopes to show other people with diabetes what they can achieve in relation to sport.
