Run 4 Wales has been closely monitoring the ongoing Coronavirus situation and the guidance issued by the Welsh and UK Governments, whilst making arrangements to deliver a COVID secure event in the Spring of 2021.

We had watched with optimism over recent months as lockdown restrictions had eased and successful pilot events across the UK have demonstrated that it is possible to safely deliver mass participation events. It is now clear however, against a backdrop of rising cases, freshly imposed lockdown restrictions and a turbulent winter period ahead that it will not be possible to deliver an event of this size and scale by March of next year.

With regret therefore, we now need to inform you that the 18th edition of the Cardiff University Cardiff Half Marathon (CHM), originally scheduled for 2020 before being postponed until 28 March 2021 will need to be postponed further, until Sunday 3 October 2021.

The knock-on impact of this decision means that the 19th edition of the CHM will also be held one year later, on 2nd October 2022, so there will not be two editions of the race in 2021 as originally planned.

The health and safety of our runners, volunteers, event team and the wider population is of the utmost importance to us. We have therefore been working closely with the Welsh Government and other mass participation event organisers across Wales and the UK to chart a safe return to events.

In 2021 Run 4 Wales will initially deliver a number of the smaller events within its portfolio, with additional hygiene and social distancing measures in place, building up to the much-anticipated return of the CHM in the autumn.

There are a number of options available to runners who are registered for the 18th edition of the CHM, now postponed from 28 March 2021 to 3 October 2021.

Every runner with a place will be able to use it in the rescheduled event on Sunday 3 October 2021 or decide between a number of additional options, depending on their entry type.

If you are registered, you will have received an email today with more details on the options available to you (which are also detailed below). If you are yet to receive an email, please check your junk mail or click below for details on the various options and how to proceed with your preferred choice.

If you are registered for both editions of the scheduled 2021 events (March and October) you will have received separate instructions and dedicated options via email.

We understand and share your disappointment with this outcome but thank you for your understanding in these difficult and unprecedented circumstances.

Our thoughts remain with those directly impacted by COVID-19.

With best wishes,

The Run 4 Wales team
