Megan Boxall, who lives in Thorpeness, Suffolk, decided to run around Britain’s coastline after going into a “really dark place” with her mental health in 2024.
The 33-year-old hopes the challenge will raise awareness and money for the Samaritans, who helped during five calls at the hardest of times.
She is now on track to smash the current record by an astonishing 94 days, despite gale force winds, a lack of washing facilities and running through the depths of a Scottish winter.
The Suffolk runner was also diagnosed with multiple sclerosis last year and says running along the coast has been a “sanctuary” from her worries.
Miss Boxall, speaking to this paper from Aberdeen, said: “One day in January 2025, I was running in Sizewell.
“It was the first time I felt happy in so long, and suddenly it felt worth it.
“That was when I decided I wanted to do this, especially by the sea, where I am happiest.
“I think it’s the views, the horizon, the sound of the water, the vastness of it all, it’s where I’m happiest.
“I just hope what I am doing helps other people.”
Mrs Boxall began her 5,240-mile journey at Sizewell Beach on October 18, 2025, running down the coast to Land’s End in Cornwall, along the Welsh Coast, up to John O’Groats in Scotland, and she is now climbing back down to Suffolk.

The route consists of 200 marathons, with the sea to her left-hand side during the whole route.
Her dog Shadow also joins her on parts of her runs, with the pair sharing “the most beautiful views” together.
Her journey also carries personal significance, following in the footsteps of her late uncle, who walked the same coastline aged 33 after being diagnosed with Parkinson’s disease.
Miss Boxall is set to return to her starting point at Sizewell Beach, Suffolk on May 9.
To mark the end of her challenge, she plans to finish where she started then take part in the same local Parkrun that began her journey.

“After that, I’ll be celebrating with friends and family in the local pub.”
And she’s not stopping there. “I’m already thinking about what’s next while I’m out running,” she adds. “Later this year, I’m hoping to break the record for the fastest marathon run by a woman with MS.”
