On 12 October 2025, the National Breast Cancer Research Institute are asking runners nationwide to take part in the Chicago Marathon in aid of breast cancer research.

Based at the Lambe Institute, University of Galway, the National Breast Cancer Research Institute is a national charity that funds a comprehensive research programme at the University of Galway lead by Professor Michael Kerin. Recent World Health Organisation Figures in 2020, show there were 2.3 million women diagnosed with breast cancer and 685,000 deaths globally. As of the end of 2020, there were 7.8 million women alive who were diagnosed with breast cancer in the past 5 years, making it the world's most prevalent cancer. In Ireland, 1 in 7 women will develop breast cancer during their lifetime. It?s the second most common cancer in Irish women in Ireland after skin cancer and the most common cancer in women over 50.

The role of the National Breast Cancer Research Institute is paramount, as its research can help to ascertain the causes and factors that influence breast cancer and therefore help to develop effective screening, treatments and medication to combat it internationally.
