Zone 2 is 70-80% of heart rate max. Most of your training in 60-75% would pretty much cover that. You are primarily burning fat as fuel (which even elites have lots of) and as you start to get anaerobic, you shift from primarily fat to glycogen, which is limited to 90 minutes to 2 hours for pretty much every human. Your training sounds like the definition of how to improve and train - two quality sessions that get you about 20% hard work and the rest is easy or long.Curious what zone 2 is. Not heart rate beats per minute, but in terms of percentage of max heart rate.
Before my knees gave out, most of my training was 60% - 75% max heart rate. Then I'd add one interval workout at threshold, 85% - 90% of max, and one interval workout at 90% and over. Don't forget the strength workouts.
The thing I am now starting to read up on is for long runs, building in race specificity (race pace). I do think this was an issue for me, as in my last half, my heart rate didn't get super high, but I probably left minutes on the table. Because I was pacing ahead of my projection, I was afraid I would crash out. Looks like I erred on the other side.
I am living and learning.
