Dan Williams

UK-based runner, philatelist and founder of Apollo’s Lots Stamps.

Main interests include Great Britain stamps and research, alongside a long held interest in ultra-running and endurance challenges.

Between 2016 and 2022 I completed a number of ultras and Fastest Known Time (FKT) challenges, including the Isle of Wight Coast Path.

Following major spinal surgery in 2024, I have gradually returned to running and hope to document selected reports, articles and projects here.

Although subjects here may appear different, many of them are connected by a similar curiosity. Whether exploring running themes, stamps, marketplace discovery or search systems, I am often interested in how patterns emerge, how relationships form, and how people navigate systems.
