Tough Mucka 2026
Entry cancellation due to postponement
Event Rescheduled to Sunday 4th October
We are sorry you can no longer make Tough Mucka 2026. Postponing an event is never taken lightly, and hugely impacts the fundraising potential for our charity.
The new event date is our pre-agreed contingency date (as per our event T&Cs), to minimise disruption to farmers, landowners and suppliers.
Tough Mucka is our biggest fundraiser of the year, and all funds received from entry fees support our mental health education programme in schools – equipping the next generation with resilience and essential mental health skills. We’d be grateful if you’d consider a donation to Isle Listen, even if not your whole entry fee.
The deadline to request a refund is 5pm on Wednesday 30th September.

We are working to empower future generations to understand and better take care of their mental health. Every penny raised goes directly toward making a real impact on local lives.
