A Pembrokeshire teacher is stepping up to a half marathon challenge on the Great Wall of China in support of her brother who is waiting for a kidney transplant.

Emma Hughes of Tenby, who works at the British International School in Shanghai, is running the race today, Sunday, for the Kidney Wales Foundation.

Her brother, Adam, who is a learning support assistant at Greenhill School, was diagnosed with kidney failure in April 2013 and is now undergoing daily dialysis whilst on the kidney transplant waiting list.

The Great Wall of China half marathon course is regarded as one of the toughest in the world, including 5,164 steps - some up to 18 inches deep.

Emma, who formerly taught English at Greenhill and now teaches English to International Baccalaureate students in Shanghai, can be sponsored on
