Bellies will bounce and beards fly when hundreds of Santas make their 21st anniversary, annual charity jog through Princes Street Gardens in the Edinburgh Santa Fun Run and 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 registration (9.30am-10.45am) and 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.
