Sanna -Against The Tide is the story of ultra runner Sanna Duthie’s attempt to run the entire 186 miles of the Pembrokeshire Coast Path in under 50 hours.
Harrier PRO Trail Team athlete Sanna set out on her attempt on Thursday 24th April and thing’s didn’t 100% go to plan but the grit, resilience, and raw determination she showed are exactly why we’re so proud to have her as part of the Harrier team.
Watch the highs, lows, and everything in between as Sanna takes on one of the UK’s most iconic coastal trails. Filmed by Stephen J Reid, this 35 minute film shows the real story, not just of a record attempt, but of what it means to dig deep, listen to your body, and make big calls in the toughest moments.
When you're chasing big dreams on the trails, it’s never just about the finish line. It’s about the adventure, the lessons, and the community you meet along the way.
