Running & Fastest Known Times (FKTs)

Published: 28 May 2026 by Dan Williams

Before injury/surgery, I spent several years taking part in endurance and ultra-distance running, particularly long-distance trail and coastal challenges.

Most of my running took place between 2012 and 2022, ranging from local club races through to ultra-distance trail events, 12 and 24-hour races, and supported Fastest Known Time (FKT) attempts.

I was a member of Isle of Wight Road Runners, now with West Wight Road Runners, and regularly competed in endurance trail events across the South of England, with a particular interest in long routes and self-navigation challenges.

Some of the more notable runs included:

  • Isle of Wight Coast Path FKT — 70 miles in 12 hours 25 minutes (2018)
  • Dorset Coast FKT / first known time attempt (2019)
  • Multiple podium finishes in 12-hour trail races
  • 100+ miles at the Monster Ambit 24-hour event
  • Various long-distance route-based challenges

Several reports and articles from that period are preserved below. Some were originally published on now-defunct personal websites and have been lightly restored and republished to preserve the original write-ups and references.

A last minute decision to run a marathon around Goodwood Motor Circuit, as a training run, late 2019. Trackside company from The Stig made the photographs from the day even better.

Beach Running at Durdle Door 2018

These photographs were taken during a separate filming and photography day for White Star Running, rather than during the Dorset Coast FKT itself. Durdle Door was, however, part of a coastline I knew well from training and route recces. Photographs by Lee Collier.

Although most of my day-to-day focus is now on Apollo’s Lots GB Stamps, running and long-distance challenges formed a significant part of my life for a few years.

Following major spinal surgery in 2024, my running became more limited, although I have attempted to return to training and completed the Isle of Wight Marathon in 2025. I still hope to take on further races and ultra-distance challenges/events in future.
