Ciara Mageean, the Irish record holder at various running distances and the gold-medal winner of the European 1,500 meters in Rome in 2024, has died at the age of 34.
Mageean made public in July 2025 that she had been diagnosed with stage four bowel cancer.
A statement on Instagram confirmed read: "At 6:30am this morning, Ciara lost her battle with cancer surrounded by her loved ones.
"A beloved daughter, sister, wife, friend and inspiration to so many, she will be deeply missed.
"Ar dheis Dé go raibh a hanam.”
Mageean, a native of Portaferry, Co. Down, married her partner Thomas Moran on Oct. 12.
The runner represented Ireland at the Rio 2016 and Tokyo 2020 Olympic Games in the 1500m even, but an injury ruled her out of the 2024 games in Paris, a one day before her first heat at the Paris games.
Along with her European gold in 2024, she won European bronze in 2016, silver in 2022 and she also claimed silver at the 2022 Commonwealth Games.
Mageean holds Irish records in the 800m (1:58.51), 1000m (2:31.06), 1500m (3:55.87) and mile (4:14.58).
The champion runner told RTE she was determined to "fit as much living into the years I have left.
"I am so grateful for the support of the Irish nation," she added. "It's been there for me throughout my entire career. But I feel supported and loved throughout this journey."
Taoiseach Micheál Martin said he was deeply saddened by her loss: "As European champion and an Olympian, she inspired so many with her outstanding performances and brought immense pride to Ireland
"Ciara has left a remarkable sporting legacy. Ciara faced her recent health battles with great courage and dignity.
"My heartfelt sympathies go to her husband Thomas and all her family and friends.”
First Minister Michelle O'Neill said Mageean "will be remembered for her warmth, courage and tremendous strength of character", and deputy First Minister Emma Little-Pengelly referred to her as "an inspiration to many.”
Athletics Ireland released a statement, saying, ”Ciara was a much-loved and inspirational figure who touched the lives of so many. Her courage, warmth and spirit will leave a lasting legacy.
"The thoughts and heartfelt condolences of everyone at Athletics Ireland are with Ciara's family, friends and loved ones at this incredibly difficult time.
