It has been ranked as the country's toughest parkrun.
But the weekly race along Great Yarmouth's north beach has been helping a local teenager with autism realise her dream of becoming a top photographer.
Emily Metcalfe, 14, suffers from anxiety and often feels overwhelmed in social situations.
That began to change last August after she spotted a post in a local Facebook group asking for a photographer to volunteer at the Great Yarmouth North Beach parkrun.
“My mum responded to the post, and we went down together that Saturday," Emily said.
“It was very scary for the first week and I let my mum do all the communicating while I hid behind my camera where I was happy."
As the weeks have gone by, she has become more relaxed.
"I feel so much more confident and I rely less on my mum to enjoy my Saturday mornings," she said.

Emily has now volunteered at 10 parkruns and said the experience has allowed to her to improve her photography skills and develop her own style of taking photos.
She said it has also helped her realise that her autism will not stop her from reaching her dreams, and that with the right support, understanding and acceptance she can do all the things that others can do.

“I have received positive compliments and that has really helped boost my confidence," she added.
Now Emily hopes that her experience will inspire others in a similar situation to try new things even if they seem "frightening or impossible".
“If I can do it, I know they can too," she said.
Emily is one of the 250,000 people taking part in parkrun every week and she said the community of eight million parkrunners registered to the charity has helped her.
“Everyone has been so kind and supportive and I never imagined that I would feel part of such a big community.”
