fastest known time
the arc of attrition
This documentary follows endurance athlete Mike Samuels on a mission to etch his name into the history books—by setting the Fastest Known Time (F.K.T.) for the Arc of Attrition Double.
The Arc of Attrition is no ordinary race. It’s a 100-mile winter ultramarathon along Cornwall’s rugged coastline, widely regarded as one of the UK’s toughest endurance events. But Mike isn’t planning on stopping at the finish line. His goal? To run the entire brutal course—and then turn around and run it all again and set a world 1st in the process.
Set against the rugged beauty of some of Cornwall’s most iconic landmarks and treacherous trails Mike must navigate over 200 miles of unforgiving coastal trails, towering cliffs, mud, wind, and bogs.
Fueled by grit, caffeine, and a brilliant support crew (plus a familiar ‘straggler’), what unfolds is not just a test of physical endurance—but a raw, intimate look at friendship, suffering, and the unrelenting pursuit of something extraordinary.
This is a story of pain. Of persistence and of unbreakable will.

the bob graham round
In the rugged heart of England’s Lake District, is one of the most storied institutions in British fell running.
The ‘Bob Graham round’.
Covering over 132 miles, summiting 84 peaks, and climbing over 54,000 feet of brutal elevation — the equivalent of scaling Mount Everest twice — the Double Bob Graham is not just a test of physical endurance, but of suffering, strategy, and teamwork.
Caspian James’ Fastest Known Time is a gripping documentary that chronicles Caspian’s audacious attempt to break the course record for the Double Bob Graham Round — a feat so extreme, fewer than a handful have ever dared try.
But this film is not only about Caspian’s relentless drive to break a record — it’s about the invisible engine behind every great endurance effort: the crew.
The documentary pulls back the curtain on the small, committed team that mobilises in the dead of night, navigates the ever changing conditions, juggles nutrition, schedules, and emotion — all to keep Caspian on target.
It is a story of relentless drive, camaraderie, and the extraordinary lengths people go — together — in pursuit of something greater than themselves.
Coming soon.
