Bellies will bounce and beards fly when hundreds of Santas make their annual charity jog through Princes Street Gardens in the Edinburgh Santa Fun Run & Walk.
The circuit around the gardens is around 2.5km, so even the most sleigh-bound Santa Claus shouldn't have too much of a problem wobbling around. Some Santas may choose to walk.
Santas will be on their marks from 11am, following a good warm-up.
It's all for a good cause: proceeds from the Edinburgh Santa Fun Run & Walk will be donated to When You Wish Upon A Star. The charity specialises in "making dreams come true" for children with life-threatening illnesses.
Register ahead on the website, or on the day from 9.30am.
