MMM 2021 Date Change

Due to other large events moving their dates because of COVID, we are changing the date of the 2021 Mourne Mountain Marathon to the 11th – 12th September 2021. It will take place the week before our usual date of the third weekend in September.

The Belfast City Marathon has been moved to our usual weekend of 19th September and we feel this would impact our event by drawing on volunteers and participants – not so much full marathon runners but more likely people doing the relay.

We hope you can still make our event and that we have given you enough time to slot the date into your diary. We plan to open entries in May 2021.

Enjoy the holidays!
