Relentless by David Gething
Relentless! This is a perfect description for NRG athlete David Gething, he has raced some pretty incredible races over the years but his 7 Marathons in 7 days on 7 Continents really set a new bar. And he has written a great book about his race, this gives some great insight into what actually happens and the interactions that make the event even more challenging.
