St Albans Stampede - 12hr Enduro!

St Albans Stampede - 12hr Enduro!

The St Albans Stampede is an ultra marathon running event, held in the beautiful Hertfordshire countryside, covering parts of Heartwood Forest and Nomansland Common.

The challenge is to cover the most amount of distance (four-mile loops) over a designated time period of 12 hours – this can be undertaken solo, as a pair or as a team relay (up to 4, and up to 8 person options). New for 2024, prizes will additionally be awarded for the winning mixed and female pairs and teams.

It’s worth noting that the category winners will be awarded on distance covered only. In other words, you don’t have to run the full 12hrs to have successfully completed the challenge. The 12hr duration is simply the maximum allowable time. All entrants, even those that run for 1-2hrs, will have successfully participated in the event and be awarded a medal for their efforts.

If participants from the 100 Marathon Club want to stop at marathon distance to record a successful completion, this is very much acceptable - however they will need to record a full 7th lap so will cover at least 28 miles.
