Three life-saving friends are gearing up for a charity challenge that will see them carry out a five-day trek over Scandinavian mountains and glaciers.

Medics Martin Grove, Adam Wright and Rod Wells will be taking part in the Fjallraven Classic 100km trek through sub-Arctic Sweden next month in aid of the Suffolk Accident Rescue Service (SARS).

Mr Grove, an emergency medical technician and firefighter from Beccles, Mr Wright, a paramedic from Ormesby, and Mr Wells, a critical care paramedic and SARS responder from Gorleston, have been gearing up for their trek by walking along stretches of the east coast.

They hope to raise £2,000 and so far they have raised more than £990 on their fundraising donation web page - www.justgiving.com/fundraising/Sub-artic-trek

SARS provides volunteer specialist doctors and paramedics to assist the region's ambulance service.
