Adults, children, dogs and even Captain America took part in the Thetford Parkrun as it celebrated its third birthday.
Around 180 runners put on their running shows and fancy dress outfits to celebrate the anniversary of the weekly 5km run.
Runners of all ages and abilities took on the route around Abbey Meadows cheered on by family, friends and walkers enjoying the park's pretty surroundings.
The runs were set up to help people get and stay fit and are known for the family atmosphere.
Among those taking part and running his first official Parkrun was four-year-old Freddie Dale.
Freddie's mum Marie Dale, from Thetford, said: 'He's been coming for about two years, since he was in his pushchair. He now walks and runs it. He turned four on Friday and that meant he could be officially registered.
'The parkrun is a real family event. There is no pressure. You can walk to get exercise. The atmosphere is great and it doesn't matter about your ability.'
Anne Elrick, from Brandon, celebrated running her 100th park run.
The 42-year-old said: 'There was lots of cheering. I was high fiving the little ones - I like to motivate people as I go.
'There is a real family spirit and all shapes and sizes can take part. I love it.'
