The Final Chapter of the Yorkshire Beast Trilogy, and it’s been worth the wait!

This is the final challenge in the Yorkshire Beast endurance trilogy and the biggest yet.

In June 2026, Martin Mansell will attempt to cycle the entire perimeter of England, covering approximately 2,000 miles around the country's coastline and borders in the fastest time possible.

Starting and finishing at the Humber Bridge in East Yorkshire, the route will follow England’s coastline before tracing the Welsh border from the Severn Bridge to Chester and the Scottish border from Carlisle to Berwick-upon-Tweed.

This isn’t just a long ride. It’s a test of endurance, resilience and determination. The challenge will require 16–17 hours in the saddle each day, with only a few hours of sleep, while navigating the demanding terrain of Devon, Cornwall and England’s rugged coastline.

What began three years ago with a ride around Yorkshire now reaches its final chapter, a world-record attempt around the full perimeter of England.

The Route

Starting at the Humber Bridge in East Yorkshire, Martin will set off on a 2,000-mile journey around the full perimeter of England.

The route follows the entire English coastline, before tracing the Welsh border north from the Severn Bridge to Chester, and then continuing along the English-Scottish border from Carlisle to Berwick-upon-Tweed. From there, the route returns south along England’s north east coastline back to Yorkshire.

The challenge includes some of the toughest terrain in the country, particularly through Devon and Cornwall, with long daily distances and minimal recovery time.

The goal is simple but brutal: complete the full perimeter of England in the fastest time possible.
