An invitation to open a new circular walking trail in Pembrokeshire proved to be a miracle cure for injured broadcaster Trevor Fishlock.

Mr Fishlock, famous for presenting a television series based on walking in Wales, was invited to open the 67-mile Preseli Circle, but shortly afterwards injured his foot. He saw the invitation as a motivation to recover. "I don't think it would have been appropriate to open a footpath looking at best like a wounded rook and at worst like Long John Silver," he admitted.

The Preseli Circle was developed by the Pembrokeshire Greenways partnership, an initiative to encourage local residents and visitors of all abilities to access the Pembrokeshire countryside on foot, bike, bus and train. It offers seven days' walking through north Pembrokeshire.

It was developed by Planed with the county council and the National Park Authority, through the Pembrokeshire Greenways Partnership and the North Pembrokeshire Tourism Group.

Trevor Fishlock described the trail as a 'brilliant idea'. The route, he believed, reflected the deep pride people felt for Pembrokeshire.

For ten years Mr Fishlock worked as a foreign correspondent, but wherever he was in the world he always tried to spend the New Year in Newport. He would make his annual pilgrimage to Carningli on New Year's Eve and he recently found himself back in the shadow of that landmark as he launched the Preseli Circle.

He was joined by dozens of walkers and representatives of the Pembrokeshire Greenways partners, including Joan Asby, co-ordinator of Planed. She is confident the walk will encourage people to visit the area without their cars, with the consequential environmental and economic advantages.
