'We don't stop running because we get old. We get old because we stop running.'

Is it inevitable that our running performance slides as we get into our forties and beyond? Or are there things we can do to slow or even pause the decline, master our midlife and use experience as a superpower and become an ageless ace?

In Run Forever, record-breaking GB ultrarunner Damian Hall, fifty, examines the reasons why our strength and speed might deteriorate, yet how it isn't certain if we choose to do something about it. In running, like other sports, there have been phenomenal performances from masters athletes, and while ageing is unavoidable, how we age isn't. Becoming an ageless ace has potentially extraordinary healthspan and longevity benefits away from running.

Featuring chapters on speed, strength, mindset, sleep and nutrition, Hall draws on the knowledge of experts and shares the stories of other runners - including five-time Olympian and European 10,000 metres champion Jo Pavey, and record-breaking ultrarunner Nicky Spinks - to provide advice for how we can keep running strong and enjoying it for as long as possible. World-renowned sports dietician, author and ultrarunner Renee McGregor explains how ageing affects female runners, especially around perimenopause and menopause, and leading strength and conditioning coach Pete Stables provides knowledge and exercises for the masters athlete.

Ageing is inevitable. Slowing down is optional. Run Forever gives you the tools to keep moving - stronger, smarter, longer.
