After a very successful day at the An Cuan Games in Maynooth, our students travelled to Tullamore Harriers for a fantastic day at the Offaly Sports Partnership “Athletics for All” event. With lots of fantastic performances, teamwork, and support on show, our excellent athletes came home with smiles, memories, and medals.
Well done to all! A huge thanks to our amazing team of SNAs and teachers who travelled with the group.

This is a vital area of learning, and we were delighted to welcome Martin Moules and his local team, who delivered the training.
