Staff from an estate agents will be saddling up to cycle 100 miles without leaving town.
Staff at the Haywards Heath branch of Cubitt and West will take turns to ride an exercise bike to raise funds for the Martlets Hospice and Action Medical research.
David Dunham, branch manager, said: “Theoretically, each of the five of us should manage at least 20 miles. That might not sound like a lot to most people, but for estate agents it's quite a challenge.
“Still, the exercise should be good for all of us - particularly in view of the fact that along with teams from other Cubitt and West offices across the region, we are also planning to take part in the Blenheim Charity Triathlon next month up in Oxfordshire.”
The exercise bike will be set up in a number of different locations around the town centre tomorrow
