Today I get to speak with TriSpecific athlete John Rutherford after his recent first time Ironman  a couple of weeks back at Ironman Switzerland. John had great IM debut going 9:34.

As I say in the intro. Nobody comes from nowhere … and what I mean there is that we all have backgrounds and most athletes that have quick success in this sport have a solid background and John is no different here. John has ran 100 mile ultras and he definitely wasn’t successful in those first outings, especially as the typical carb dependant athlete and we go into all that but his background goes further back and we look into the lessons that cross over from flying a F-18 to performance in other areas of life. And don’t miss what John did with a 40 Million dollar aircraft at 14:55 into the podcast.

What We Cover:

Keto Force (Disclaimer: I have not tested this yet, but from John’s testing it seems to work well. However.. as per previous blog.. get the other aspects down first. No short cuts!)
