On Friday, McGraths Limestone Cong hosted our charity event, Mindful Miles, in support of @mayomha. We gathered at the Neale GAA Pitch, to take part in a team relay challenge, with the goal of collectively walking and running the distance of a marathon. Thanks to the incredible effort of everyone involved, we exceeded our target, completing 255 laps, covering the equivalent of 5.5 marathons! 🏃‍♀️🏃‍♂️ We were delighted to welcome Mayo footballers Tommy Conroy, Tom Lydon and Pádraig O'Hora, from Mayo Mental Health Association, along with Lianne McManamon and John Hughes. So far, we have raised almost €10,000! A huge thank you to everyone who has donated, participated, volunteered, and supported the event! Can you help us get to 10K? Following a fantastic afternoon of fundraising and team spirit, we enjoyed a cruise on Lough Corrib with Corrib Cruises. A sincere thank you to Captain Pat Luskin and his crew for taking care of us, and for the great food from Bia at Home.

🌱 Soil Success Starts with Lime Applying lime helps correct soil acidity, improving soil pH and making nutrients more readily available to plants. This supports stronger grass growth, better fertiliser efficiency, and improved farm productivity. By maintaining the correct soil pH, farmers can grow more grass, reduce feed costs, and maximise the return on their investment.
