Around 300 people took part in the event, which was held at North Yorkshire Water Park at Wykeham.
Participants walked, jogged or ran a 2.5K or 5K route around the lake, with some intrepid Santas event trying out stand-up paddle boarding afterwards.
Susan Stephenson, communications and marketing manager at Saint Catherine’s, said: “We had a fantastic, fun-filled morning and it was wonderful to see so many Santas of all ages – and some very well dressed canine companions too!
“A huge thank you to everyone who came along on the day, everyone who helped out and to North Yorkshire Water Park for the fantastic venue.
“We are hoping this event will raise thousands of pounds for patient care and will let everyone know when we have a final total.”
James Whitehouse, operations manager at North Yorkshire Water Park, said: “We were thrilled to host the Santa Dash this year and it was wonderful to see everyone getting into the festive spirit dressed as Santa Claus!
“Our Santa Stand-Up Paddle boarding challenge was a highlight, and it was great to see everyone in their best festive attire enjoying themselves whilst supporting and raising funds for Saint Catherine’s Hospice.”
