Organiser's Description

We’re back again at the wonderful Horspath Athletics with a new track record to beat and even more time to run around in circles in! The incredible Alex Marshal absolutely demolished our record of 505 at the 2025 event so if you want to claim the cash prize, you will have to now break 545 laps! This years event will be open for a whopping 48 hours! with a selection of different time slots to take part it.

How far can you manage in your chosen time frame? Can you beat our record? A mental challenge even more so than a physical one this summer. 400 Meters isn’t far, but those laps start to add up pretty quickly.
