The deal is members of the public do the race dressed as St Nicholas to raise funds for When You Wish Upon A Star, a charity that makes dreams come true for children with life-threatening illnesses.
If you're against making dreams come true for children with life-threatening illnesses, you can always take part in the run in a stolen Santa suit and spend your sponsorship money on gin.
There's also a Santa's Little Helper Run for kids. Each entrant gets a free felt hat and the satisfaction of knowing they've made a difference. And they got a hat out of it. Magic.
The first event kicks off in Leicester's Victoria Park on December 2.
