Ciara Mageean, the European 1,500m champion and one of Ireland's best‑loved athletes, has died aged 34 after a battle with stage four bowel cancer, her family have announced.

Her family said she died at 6.30am on Sunday 1 November, surrounded by loved ones. A statement on her social media accounts said: 'Ciara lost her battle with cancer surrounded by her loved ones.' It described her as 'a beloved daughter, sister, wife, friend and inspiration to so many'.

Mageean, from Portaferry, County Down, married her long-term partner, Thomas Moran, in a civil ceremony in Belfast earlier in October. The couple held a wedding celebration on 25 October, a week before her death.

Diagnosis Made Public in 2025

Mageean was diagnosed in May 2025, less than a year after winning European gold in Rome. She announced in July 2025 that she had cancer, saying she was ready to face it with 'the same fight I've always brought to the track'.

In June 2026, ahead of the publication of her memoir, My Greatest Race, she disclosed that the disease was stage four bowel cancer. The book, written with journalist Clíona Foley and published by Gill Books on 18 June, charts her career and illness. She said writing it was a welcome distraction during her treatment.

In interviews around its release, she spoke candidly about her prognosis, telling The Irish Times she 'probably won't make my 40th birthday'. She also said she did not want to be known as 'Ciara the cancer patient'.

Her death came more than four months after the memoir was published.

European Champion's Record-Breaking Career

Mageean won 1,500m gold at the 2024 European Championships in Rome, becoming the first Irish individual European champion since Sonia O'Sullivan.

A two-time Olympian, she competed at Rio 2016 and Tokyo 2020, but an Achilles injury forced her out of the Paris 2024 Games. She finished fourth in the 1,500m at the 2023 World Championships in Budapest. She also set Irish records over 800m, 1,000m, 1,500m and the mile, including marks held by O'Sullivan.

Born in Portaferry, she attended Assumption Grammar School in Ballynahinch.
