The Suffolk Trail Festival 24 Hour Challenge is a 24 hour individual or team relay race held at Shimpling Park Farm, between Bury St Edmunds and Sudbury in the very heart of the beautiful Suffolk countryside.

You can enter as a solo runner, as a pair or as a team of up to 8 runners and the aim is to complete as many laps of our 5 mile course as possible in 24 hours. This is a test of speed, fitness, endurance, mental toughness, tactics and teamwork!

It doesn’t matter if you want to enter the event for fun and to spend a bit of time with your friends, or if you are a serious ultra-runner, everyone is welcome. The social side of the event will be amazing, and we guarantee you will meet some wonderful people and form some fantastic friendships along the way!
