25 Hour Track 100 mile

On the night the clocks go back, you will have 25 hours to complete a unique 100 mile track ultramarathon. You will race on a quality floodlit 400m outdoor athletics track in Huntingdon, using a professional track timing system provided by Timing Monkey Ltd.

This challenge is ideal for beginners to get a 100 miler that is required for the harder events; for those looking to crack a PB; or individuals seeking a Spartathlon qualification. ​

The event will take place weekend of 28/29th October 2023 when the clocks go back for winter, giving you an extra hour to complete your 100.
