Unsinkable: The Story of Alan Corcoran’s Journey Through Grief and Resilience
In 2017, Alan Corcoran attempted to swim the length of Ireland, but his support boat sank in County Down after 210 kilometers of swimming, forcing him to abandon the challenge. But he didn’t give up. With a £13,000 bank loan and a new support boat named UNSINKABLE II, he successfully completed the 500-kilometre sea swim in 2019, from the Giant’s Causeway in County Antrim to Tramore in County Waterford. The swim was a tribute to his father, Milo Corcoran (the former president of the Football Association of Ireland), who passed away from cancer in 2016, just three weeks after being diagnosed.


This swim is documented in a feature-length independent film called Unsinkable, which he co-created with Waterford-based creative agency Emagine. The film has already won acclaim, with Demand Film securing distribution rights for Canadian cinemas and theaters this summer.
The documentary explores the deeply personal motivation behind Alan’s swim. Raising €30,000 for cancer and stroke charities in memory of his father, Milo, the film examines how Alan channeled his grief and negative emotions into a powerful and inspiring adventure. By following Alan’s journey, viewers will witness the transformative power of setting a challenging goal and committing oneself to achieving it.

Alan’s accomplishments don’t stop there. His debut book, Marathon Man: My Life, My Father’s Stroke, and Running 35 Marathons in 35 Days, won numerous awards, including the BIBA Book Awards, IPPY Book Awards, Readers’ Favorite Book Awards, and ABF Best Book Awards.
And there’s more to come from Alan. He is set to publish an autobiography called Unsinkable in the summer 2023, which will undoubtedly inspire readers with his story of overcoming adversity and using his challenges to help others.

“MARATHON MAN is an uplifting story of an extraordinary achievement – all the more inspiring given that the author was an inexperienced long-distance runner and only 20 when embarking on his mission to run 35 marathons in 35 consecutive days. Alan Corcoran’s response to the shock of his dad’s stroke was to get active, create positive from negative and raise money for charity. Alan faced many obstacles in life and along the gruelling 1,500-kilometre road around Ireland’s coast. He candidly submerges the reader into his world with a charming, light Irish touch, showing how you can achieve your objectives through sheer perseverance.”
