Regiment Fitness raised £200 for the National Trust charity at the Jingle Jog on Saturday.
Families and individuals dressed in festive costumes and carried logs round the route at Dunstable Downs.
Steve Nodwell, event organiser, said: “We hoped there would be a bigger turn out but we did manage to raise £200, hopefully we can raise more next time.”
Mark Wadsworth won the prize for Best Dressed Santa.
The National Trust charity aims to protect historic places and green spaces.
