A woman is undertaking a static cycle ride in the foyer of Daventry Leisure Centre on Saturday.
Gwen Holmes will be on her bike for six hours and also hopes to arrange a raffle. She wants to raise funds for Whizz Kids who improve the quality of life for disabled children.
Later this year she will be running in the London Marathon for the same cause.
