A determined teacher sets off on a 100-mile charity trek today that will take her along the length of the north Norfolk coast and through the seaside village where she played a starring role in the Christmas nativity.

Rebecca Wass, who played Mary in Mundesley's live production of the Christmas story, begins her five-day border to border walk in King's Lynn and will be circumnavigating the coast to finish in Hopton on Sea on Monday.

But the trek will be particularly gruelling for the 31-year-old creative arts tutor as she suffers from fibromyalgia, a chronic condition that causes widespread pain and profound fatigue.

She put aside her condition to ride a donkey through the streets of Mundesley as Mary in December, and will again be tackling the condition's symptoms to complete the walk, which is raising money for the Fibromyalgia Association UK.

A team of nine friends will accompany her and have offered to carry her should she have a fibromyalgia flare up along the way.

Miss Wass, from Gertrude Road, Norwich, said: 'I do struggle quite a bit with walking sometimes so it will be hard but I've been doing quite a lot of training and we have been going on some group walks at weekends.'

She and her team of friends will travel from Wells to West Runton on Saturday then push on to Mundesley on Sunday, stopping off at the Ship Inn at around midday to meet supporters.

They are hoping to raise �2,000 through their efforts and have already passed the �1,400 mark.
