Sanna Duthie smashes Pembrokeshire Coast Path record

The gruelling challenge took Sanna from Amroth to Poppit Sands, following the spectacular coastline and tackling steep climbs, rugged terrain, and some of the most exposed sections of the National Park. Her achievement beats her previous attempt four years ago and highlights her extraordinary endurance and determination.

Over the course of her run, Sanna battled fatigue, variable weather, and the physical strain of covering almost seven marathons back-to-back. Her effort has so far raised £2,610 for the Pembrokeshire Coast Charitable Trust, which funds vital conservation and engagement projects across the National Park.

Katie Macro, Director of the Pembrokeshire Coast Charitable Trust, said:

“Sanna’s determination and resilience are truly inspiring. Completing 186 miles in under 49 hours is an incredible feat, and the fact she has raised over £2,000 for the Coast Path makes her achievement even more meaningful. Every pound she has raised will support vital conservation and engagement projects.”

Sanna spoke of how the Coast Path has always been a special part of her life, describing the deep connection that drew her back for a second attempt:

“The Pembrokeshire Coast National Park is a really special and precious place to me. I have spent so much of my life climbing, running and walking it, whether it’s rain or shine, all year round, I am usually running in it, observing through the seasons the ongoing maintenance and conservation that is consistently required by the Pembrokeshire Coast Charitable Trust to keep it open for us all to use.

“I run Ultra Marathons for fun, having first ran the Coast Path back in 2021 from North Pembs to South Pembs in 51 hours and 35 minutes. This time I thought I would run from South Pembs to North Pembs whilst raising funds for my favourite place. Fortunately, with my most recent FKT (48 hours and 26 minutes), I have now travelled the Coast Path in both directions and seen it from all angles and in all seasons; it has been good to give something back to something that has given me so much.”

Sanna’s most recent record-breaking challenge was captured by local production company Kelp and Fern and will be the focus of a feature-length documentary, now in post-production.

Martin Larsen-Jones of Kelp and Fern described it as

“an immersive film, documenting Sanna Duthie as she attempts to run the wild Pembrokeshire Coast Path in record time. A journey of grit, grace, and 48 hours of unrelenting trail that tests her body and spirit with every step.”

Keep an eye on the Trust’s social media channels for updates on the premiere.

Sanna’s achievement not only sets a new Fastest Known Time, but also shines a spotlight on one of the UK’s most treasured National Trails – reminding us why these landscapes deserve to be explored, enjoyed, and protected.
