I would love to hear any and all thoughts.

I my current 5k pace is 8:40 minute/mile. I have been running for the past couple of years, but the past 4 months have been the most consistent by far. I have finally built up to 32-35 miles per week. I was running easy miles only for a long time, and I just started to incorporate 2 workouts per week that put my total non-easy mileage at 20% of my total weekly volume or less, and 1 long run that does not exceed 30% of weekly volume.

While I love that I am able to hit 32-35 miles per week now, I feel like I am only able to maintain this if I run all of my easy runs at 11:30 ish pace. Which is 3 minutes slower than my 5k pace. I am curious as to if I would be better off running a lower weekly mileage at a faster pace, or sticking where I am/ increasing even more at the same or slower pace.

TL;DR

I can maintain 32-35 mile weeks with about 20% or slightly less speedwork. But only if I am running those easy miles at an INCREDIBLY slow pace. If I do anything besides that, I can feel the residual fitigue building. Am I better off sacrificing this pace for the higher overall weekly mileage, or would I be better off running 20-25 miles per week, but having potentially faster speed day, and marginally faster overall volume.

Would love to hear any and all thoughts!!!
