Shoppers and staff raised more than £600 for charity when they rode the equivalent of the distance from London to Brighton - without leaving the store.
Morrisons, in Stirling Way, raised £632 for Great Ormond Street Hospital at its recent in-store cycle ride.
Staff and customers at the Borehamwood store cycled the distance from London to Brighton on a donated exercise bike at the weekend.
Claudette Hutt, who helped organise the event, said: “The day went brilliantly. The support from staff, and even customers, was amazing. We’re very pleased to have raised so much.”
Store manager Aytan Tuncel will be completing the real London to Brighton cycle ride on June 15, and was the inspiration for the in-store event.
Claudette added: “Aytan is really chuffed that we’ve raised this much. His aim was £500 and we’ve already exceeded that, which is brilliant for the charity.”
