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). Prizes will be awarded for the top solo runners and winning teams across three (male, female and mixed) categories.

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 12 hours to have successfully completed the challenge. The 12 hour duration is simply the maximum allowable time. All entrants, even those that complete just one loop, 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.

The event is licensed by the TRA and held under UK Athletics rules. Please note that under UKA rules, entrants aged 17 may only run a maximum of 25km and entrants aged 18 and 19 may only run a maximum of 45km. This distance restriction will likely prevent younger entrants from winning solo prizes, but can as part of a team.
