Staff from Frames Conservatories Direct will be getting into the saddle to raise money to help youngsters at the Rainbow Ward of West Suffolk Hospital.
The Bury St Edmunds company is spending a year fund-raising for the ward to provide portable heart monitors for youngsters and has so far raised £7,000.
On October 9 sales manager Steve Savage and managing director Adrian Lewis will join other staff and friends to complete a 290 mile ride around Suffolk and Norfolk over three days.
Staff have already climbed Snowdon and organised charity walks and a quiz night.
Steve said: “The group are mixed ability but we are all determined to complete the challenge and raise as much money as we can for such an important appeal.
“We are delighted to have raised around £7,000 already, enough to fund one portable heart monitor, and we are grateful to everyone who has supported us so far.
“Now we are ready for our toughest challenge yet. We wanted to do something that would encourage fund-raising and also raise awareness of the importance of our Rainbow Ward appeal.
