Jerry talked about how this taxed and tested 1) cardiac power output training and 2) lactate capacity training - two objectives on your path to Elite fitness. Well, I am not good at one or both of these. I was sucking wind. After round 1, my runs were slow, my C&J output low, and my stamina completely gone.
I even had a visit from Pukie in round 3/4:
This is the same feeling I get during FGB, so clearly I need to keep hitting these. As hard as they are on me.
I did not quit. I wanted to, thought about it, but kept going. Score one for stubbornness.
