Mud, Sweat and Tears – An Irish Woman’s Journey of Self-Discovery (2011)

In July 2008, Moire O’Sullivan made a solo attempt on the Wicklow Round, a gruelling endurance run spanning a hundred kilometres over twenty six of Ireland’s remotest mountain peaks. After twenty one and a half hours she collapsed, two summits from the end. Battered and bruised, yet undeterred, she returned a year later to become the first person ever to complete the Round in less than twenty four hours.“Mud, Sweat, and Tears” is the first book to tell one woman’s story about her passion for mountain running, a passion that has brought her to the heights of some of Ireland’s most impressive mountains and to the depths of her own human limitations.

“Inspiring stuff: an awe-inspiring tale of guts, passion and pig-headed refusal to surrender.” Richard Askwith, Author of Feet in the Clouds.

Blown away by the 2018 Mourne Mountain Marathon

‘800 grams?’ I asked. ‘Are you sure it’s 800 grams?’ Paul messaged me back, confirming its weight. His proposed tent for our Mourne Mountain Marathon race indeed weighed less than a kilo. My laser competition tent that we used last year was 1.2 kg, and that was considered super-light. But no, Paul wanted to shave … Continue reading Blown away by the 2018 Mourne Mountain Marathon

Finding True Adventure at Quest24 Adventure Race

This year, I have been looking for new adventures. And Quest24 delivered this, and more, last weekend. For the past five years, I’ve been doing one-day adventure races around Ireland and the UK. By the end of last year, however, I realised that the ‘racing’ part was taking over, in a stressful, competitive way. The … Continue reading Finding True Adventure at Quest24 Adventure Race
