Staff at Morrisons in Pinchbeck pedalled 89 miles in store to raise £78.11 for the charity, Action Medical Research.
A static bike was set up and staff members including supervisor Donna Bateman hopped aboard during a six-hour stint.
Donna said the supermarket chain’s regional director is doing a sponsored ride from London to Paris in July for Action Medical Research and the local fundraising will give a little extra to the charity.
Action Medical Research is the charity responsible for a series of major breakthroughs, including development of the UK polio vaccine, which has kept millions of children safe from the deadly and crippling disease over the last 60 years.
The charity also developed ultrasound scanning in pregnancy.
