RUNNER Lesa Hitchings will have to push through the pain barrier every step of the way on Sunday's London Marathon.
The 39-year-old from Baglan, who works in road safety with Swansea Council, suffers from two frozen shoulders and has diabetes.
Her shoulder problems means she cannot move her arms above her waist or behind her back. "I'm in a lot of pain whenever I run," said Lesa.
"I have been back and forth to hospital. In fact, two weeks after the marathon I'm due to have an operation on my shoulder."
Her diabetes has also affected her training but she is soldiering on.
Lesa, of Old Road, is raising money for Treat Trust Wales, which aims to develop a multi-million pound therapy centre in the grounds of Morriston Hospital.
"If there was a centre like that it would give people hope and give them something to aim for," said Lesa.
"They would be able to get help and rehabilitation.
"I think it's a really worthwhile cause."
