There are currently 14 active parkrun events in present-day Hertfordshire. The first was St Albans which started on January 9th 2012 and the newest is Leavesden Country which started on October 22nd 2022. Heartwood Forest was also a Hertfordshire event but has now closed. Ellenbrook Fields and Tring parkrun were active until the Covid-19 parkrun pause and are now also permanently closed. The name for having completed all parkrun events in the county is “King of Herts” or “Queen of Herts”

The Historic County of Hertfordshire has 15 parkrun events. It includes Oak Hill which is now part of Greater London.

I first completed the county on February 2nd 2019 at Letchworth and maintained it at Leavesden County on January 21st 2023

The interactive maps below take you to the approximate location for the course, typically the centre of the park. See the course instructions in the parkrun page for each event for specific directions to the start. Course maps show the route at the time that I ran it and may have changed since then.
