The annual Percy Pud 10km charity run awards runners with a Christmas pudding for all their hard efforts.
This is the 28th year of the event, after it was cancelled last year due to the pandemic.
Over 3000 runners are expected to attend the event and £1,000 will be awarded to any male or female athlete who sets a new course record.
Richard Dunk, the race organiser, said: “We wanted to create an event that was a bit different, and we needed a logo to go alongside the race that wasn’t too serious, so we came up with ‘Percy Pudding’.”
This is his 20th year organising the event and he said there is always a good atmosphere on the day.
Runners of all abilities will be taking part, but in 2019, triple Olympic medallist winner Eilish McColgan broke her own course record with a time of 31:48.
Nicole Hasoon, 22, fifth year Dentist student at the University of Sheffield, will be running on Sunday and heard about the race in her first year of university.
She said: “After seeing pictures of oversized Christmas puddings and neon hats, I was sold.
“The usually quiet Peak District dam becomes bustling with live Christmas music and there is a real sense of community spirt-solidarity in being freezing together.”
There is a fee to enter the race and many of the proceeds are donated to charities and organisations including St Luke’s Hospice, Cavendish Cancer Care, Weston Park Cancer Hospital Charity and Loxley Silver Band.
The race starts at 9:30am on Sunday morning along the Loxley Valley and supporters are expected to be cheering runners on, all the way along the course.
