A firefighter's swapping the fireman's pole for a paddle in a charity kayak attempt beginning in Dorset today.

Humberside Watch Manager Sean Dolan will spend up to eight hours a day in the water as he tries to kayak the distance of a marathon every day for a month, starting from Christchurch Fire Station.

The seven-hundred mile trek is to raise funds for both the Fire-Fighter's Charity and Caudwell Children.
