A Herefordshire woman who had cancer and was using a wheelchair a year ago is walking nearly 200 miles (322km) to raise money for a specialist unit.
The pair expect to finish in just over a fortnight
Liz Morawiecki, 44, from Breinton, is embarking on the challenge along 186 miles (299km) of the Pembrokeshire coastline with a friend, Pat Watkins.
Mrs Morawiecki had chemotherapy after being diagnosed with colo-rectal cancer and has since been given the all clear.
The walk is expected to last about two-and-a-half weeks.
'Build up fitness'
She is aiming to raise up to £3,000 for the unit at Hereford Hospital.
It is hoped the money will help to improve facilities at the Macmillan Renton Unit.
Her husband, Andrew, said: "We planned it (the walk) in our retirement. But cancer has taught us not to wait for things.
"She has been quite daunted by it, but she's looking forward to the challenge.
"She's been doing a lot of training over the last three months to build up her fitness and her strength."
Mrs Morawiecki, who was diagnosed with cancer 18 months ago, has checkups every three months.
