Relentless: Secrets of the Sporting Elite

Alistair Brownlee is a legend triathlete with two Olympic gold medals and more accomplishments in triathlon.
He shares his interviews with other legendary athletes from all kinds of different sports in search of how elite athletes continue to dominate and stay on top.
Stories and points made are interesting.

However one star missing piece is the structure. Epilogue at the end does a much better job in terms of structuring the themes from these interviews than the main chapters imho.
