Big Fun Run is a series of 5km untimed runs staged within scenic settings throughout the UK from June to October. All you need to do is find the one closest to you!

The Big Fun Run is strictly for fun where it’s all about relaxed exercise. No times, no pressure, no sweat - just some easy moves and lots of laughs.

The runs are suitable for all the family where you can accomplish your personal goals; whether you are raising money for a worthwhile cause close to your heart, remembering a loved one or simply keeping active.
