It was such a colourful scene that people driving past The Forest recreation ground earlier today may have had to do a double-take.
There were up to 500 runners making their way around the park covered in paint.
But it was all in the name of the Rainbows children's hospice, in Loughborough.
The inaugural Rainbow Run was labelled a big success by both organisers and participants.
The latter did a 5km run – two laps around The Forest – with a difference.
Every few hundred metres they had to go through a paint station, where marshals covered them in powder paint.
Sarah Harwood, 34, of Heanor, had a personal reason for taking part as her six-year-old son Logan has special educational needs, including autism and sensory impairments.
Sarah and her friends have taken part in a number of events to raise charity funds and also help them improve their fitness.
She said: "It's a wonderful idea. I've never taken part in anything like this before.
"Hopefully a lot of money can be raised for the charity, it is a really good cause which in the future Logan may need to use."
The hospice, in Loughborough, looks after thousands of sick children from Nottinghamshire.
Sam Herratt, 40, a family support nurse at the hospice, took part in the event herself.
"It is a real fun family event but is raising money for a very good cause at the same time," said Sam, of Aspley.
"I get to see every day the great care that is given at the hospice, so it is great we are all here today."
Twelve members of staff from Alea casino in Upper Parliament also took part, including Rebecca Deaville, 31, of Trowell.
She said: "It is a good team day out but we also recognise there is a serious side so we have been raising money with bucket collections and other means."
Her colleague Kenny Scaddan, 45, of Broxtowe, said: "I've never known an event like this before, so it is a real pleasure to have the chance to take part.
"We planned to just take it easy around the course. The fun aspect is really getting covered in paint."
Organisers from the hospice said they hope to make the run an annual event. All entrants paid £10 yesterday but also had the chance to collect sponsorship money.
Charity events manager Katie Baxter said: "We are delighted with the number of people taking part.
"We thought the paint would add to the fun and certainly add some colour.
"We had 350 people sign up in advance but we estimate about 150 more have just turned up on the day."
