We are disappointed to announce that we are postponing the 2020 Big Fun Run series.  Amidst the ongoing concerns in regard to the spread of the coronavirus and the impact this is expected to have in the UK in the weeks and months to come, we understand the requirement by the UK Government to ban mass gatherings in the interests of supporting our frontline services and public health. 

We are continuing to work closely with local authorities and our other delivery partners over the coming weeks to secure and communicate new dates for the events.  Due to park availability and the demand of the rescheduling of other major events at this time, we anticipate that the events will now take place in summer 2021. We are saddened to have to make this decision but we believe that this course of action is in the best interests of our participants, our affiliate charities and the event team who deliver the event. Those who have an existing entry will be automatically updated to the new date and we will confirm the new date to you as soon as possible.

For now, we encourage everyone to look after yourselves and those around you where you can, to continue following the advice given by the World Health Organisation to prevent the wider spread of the virus, and to continue making sensible decisions to keep others safe during this time.

Take care,

The Big Fun Run Team

  • Amazing experience from start to finish. There's strength in numbers, raising awareness and much needed funding for very deserving charities.

  • I feel by doing the 5K Big Fun Run I've gone a little way to show the gratitude I have for the neonatal doctors and nurses.
