I am averaging about 8-1/2 hours of training per week. That surprises me a bit. It feels like more than that, but on the other hand, it fits pretty comfortably into my life. I guess this also speaks to the idea of quality over quantity, particularly since I am focusing on sprint and Olympic racing this year. There is a fair amount of intensity in my workouts and it seems to be working out OK in terms of racing.
I share this always with the caveat that training is a very individual thing and needs to be appropriate to one's goals and one's life. What is right for me may not be right for you.
Truly what I like about these bar charts is the fact that there are no empty weeks! That is a huge win for sure!
Happy training :-)
