This is the OP updating my post.
Last week I readjusted some training paces and ran three key workouts:
- 12 mi long run - Ran 10 miles at the prescribed MP (6:34) then ran the last two at prescribed HM pace (6:06)
- (2x200M + 1x400m) x5 - prescribed paces (jogging equal distance recovery)
35, 35, 73
34, 35, 72
34, 35, 70
34, 35, 72
34, 34, 70
- 6 x1000m @ 5K pace - 3:34, :28, :28, :29, :28, :23 (2:30 rest)
So all in all, the paces felt okay. The repetition workout, felt okay - it was more REP pace running that I had been running before, but it felt okay. The 1000s were the first kind of interval/5K pace running that I had done for the year. So it got tougher at the end, of course. I felt like this was an okay week.
Now so far this week:
I did a Long Run easy this time, just ran right at 7-flat pace.
- First workout I did a 4 miles Threshold pace run (6:01, 6:06, 5:59, 5:59). I meant to make this a five mile run, but I was feeling like I had put WAY too much effort into running four miles right above six mile pace. So I dropped it and decided to make it four miles.
- The next day (yesterday) I ran 6 miles in the morning, and then decided to run 10 miles fast that evening. I ran the whole ten miles without looking down at my Garmin watch once, so I did not know the pace. I was running a "fast/marathon type pace" but I ran based off a "comfortably hard" pace. I finished with a 6:16 average and the last two miles in 6:02, 5:57.
... So I guess my legs just bonkered on the four mile threshold run, it felt like WAY too much effort to run at that pace. And then the next day I run comfortably hard for 10 miles and finish with the same pace in the last two miles at the end of 10, as I did with four.
I plan on running an 8x800m Interval workout this Saturday, 3K-5K pace (2:35-2:45).
So that's the update, any thoughts? I think I'm just abandoning the idea of a 4-5 mile threshold run and just turn into all my long runs into comfortably hard efforts, at marathon/half marathon pace, with 10mile pace finishes. I think that workout better suits me as a threshold/marathon workout.
