David Gething Relentless


Seven Marathons, Seven Continents, Seven Days.


Relentless: Seven Marathons, Seven Continents, Seven Days describes a unique and unparalleled global expedition. It was the ultimate intercontinental marathon race, originating in Antarctica and ending in Australia a week later, visiting every continent on the planet on the way.


Far from just covering the dry statistics, Relentless dives deep into the emotional and 

psychological side of a gruelling, multi-day stage-race. Relentless looks both inwardly into the mind of a competitive athlete, as well as at the interpersonal relationships, rivalries and bonds that form on an adventure like no other. The book gives a deeply

personal and candid view of what it is like to compete in one of the most demanding 

amateur sporting events on the planet, and what it takes to win.


“The ambition and dedication that David Gething demonstrates in his remarkable achievement shows that he has the true spirit of an Ironman: Anything is possible with the right amount of dedication and commitment.”

Andrew Messick, CEO of Ironman

“A wonderfully told adventure about pushing your limits—for runners and non-runners alike. I couldn’t put it down.”

John Ellis, international ultrarunner

“David Gething has done an excellent job of capturing the essence of the event—the characters, courses, logistics, the internal dialogues and doubts, the issues and ethics and, in the end, the sheer magnitude of it all. Gething translates the nuances of such a multiday challenge into an exciting finale both on and off the pages of the book. I was totally impressed and engrossed. An excellent

read—I would totally recommend the book.”

Steve King, Ironman, Ultraman, and ultramarathon legend
