Some families donned Santa costumes as they took on the challenge at North Yorkshire Water Park, with the course a double circuit round the lake which people could either walk or run.
The event coincided with a bumper Christmas market at the water park, with lots of stalls, food and drink on offer.
Saint Catherine’s Scarborough posted on its Facebook page: “Well that was a fun morning”
“Thank you to every single one of you who braved the cold this morning to raise vital funds for patient care at Saint Catherine’s, it was fresh but we still had fun. Together we are Saint Catherine’s.”
More details about the hospice’s Christmas programme can be found on social media and their website, with more still to be posted on the run-up to Christmas.
