The organisers of Tough Mucka have postponed the highly popular event due to the weather forecast.
Isle Listen’s event was due to be held at Ballafesson this Sunday.
The new date for the event is next Sunday, October 12, with all participants able to roll over their entry to this date, and do not need to take any action regarding this.
The charity said: “Participants that are no longer able to take part in the event on the new date can request a refund for their entry fee from Isle Listen.
“Please allow up to 10 working days to receive a refund once requested and do not contact Isle Listen during this time.
“Refunds can be requested by completing the form here: islelisten.im/toughmucka“
