Transcript: "Hey, Jamie, I'm not sure. I can remember too many workouts where I wasn't in pain, if I think about swimming, I always would going to the pool Philly fatigue. The the legs were fatigued felt like they were dragging along the bottom of the pool and just trying to keep good body position and swimming. For me was always somewhat uncomfortable and painful. The bike was a little less painful in the sense. I was sitting on something and I could actually take a little break. Every now and then but biking when your time trialling, you know can be quite painful running running. I was always in pain whether it was niggling injuries or just absolute fatigue and kind of grinding yourself trying to get the miles in or do the work. I very rarely had those moments of flow where the body was responding and it felt really fantastic. In fact, I can probably remember those workouts more than I can. The painful ones because it was just so many painful workouts, and I think that's the goal of the sport is to be a bit cliche to be comfortable with the uncomfortable. That is really what the sport of triathlon is all about becoming just comfortable with being in pain and going. This is where I'm meant to be if I want to improve. I'm not sure if that helps. Cheers."
