Thousands of runners were flushed with colour after running through the grounds of the Chatsworth estate for charity.
A crowd of 3,000 completed the 5km challenge but were not just red in the face at the end of the run - but covered in every colour in the rainbow.
The ‘Run or Dye’ event saw participants start the run dressed in white and finish it covered from head to toe in different coloured dyes sprayed on them along the route.
They were sprayed with a different colour at each kilometre point along he route and when they crossed the finish line.
Money raised by the runners will go to the Help for Heroes charity, with some wounded servicemen, women and veterans among those who took part in the event on Sunday.
The charity helps injured soldiers, sailors and airmen move on with their lives following injury and illness caused by serving their country.
It offers grants to the injured servicemen and women and runs a number of recovery centres across the UK.
Some cash was also raised for Girlguiding Derbyshire, which provided marshalls for the event.
Annette Heartfield, County Commissioner at Derbyshire Girl Guiding, said: “Being involved in the Run or Dye event at Chatsworth has been incredibly exciting and it’s been a great way to raise funds.
“Partnerships such as this one with Run or Dye are a fantastic way to help further build the girls’ confidence and raise their aspirations.”
The 5km race was followed by games for the participants where they were covered in even more dyes.
