At the age of 50, Eddie Brocklesby decided to run her first half marathon. Until that point, she'd done little running, and her exercise regime consisted of little more than chauffeuring her children to their own sports clubs. 

In common with so many people, any interest she'd shown in sport in her childhood had diminished as her adult life progressed, with spare time becoming ever more limited in the face of work and family commitments. But the half marathon was the first of what was to become a hugely impressive trajectory of sporting accolades and successes. 

After that event, and following the loss of her husband of 30 years to cancer, she completed a marathon. Now nearly 74, the past 20 years have seen her take part in marathons, triathlons and Ironman races across the globe, and she has accrued many medals and awards. 

In Irongran, Eddie looks back on her life and explains just how she's managed to develop the energy to match the enthusiasm she's always had for an active lifestyle. She shares the difficulties she's experienced in her sporting endeavours and explains how she's managed to overcome them. 

Eddie is passionate about the health and well-being of our ageing population and provides up-to-date research about why keeping active in later years is so important, along with guidance about how to remain full of life in your later years.
