Very nice week, BigRoundNumbers. I recognize these workouts from a Strava account I follow (and have been impressed by). Hope we can talk some more at New Bedford. Will you be racing there? Maybe we'll be able to work together on the course.
I'm seriously impressed by how much mileage you can do in singles on your recovery days. As you can see in my log, I have to really dial back the day after hard sessions. My only hope of getting in 10+ the day after a workout is to double.
Your back-to-back workout + long run at the end of the week shows serious fitness. But make sure you recover. As even Canova argues, there is literally no point to doing a workout that you don't recover from, because it's the supercompensation during the recovery phase, not the workout itself, that brings the physiological adaptations we need. The workout's only purpose is to make you recover from it, so don't shortchange that recovery. Especially when you are already in such good shape this far out from your goal race.
My training last week was okay - not great, not terrible. It was not a good week of mileage; I went a little aggressive on my deadlifts on Tuesday, and I must have used poor form on the last set or two because I woke up Wednesday with my back very stiff, and had to take the day off to let it loosen up. Some work stress also made me need extra sleep last week, so I didn't get in any doubles like I'd planned to. So the mileage number wasn't there, but at least I had two solid quality sessions. I have to remind myself that for most of the last three or four years, 70 was a very good week for me. So now, if my bad mileage weeks are 70, I'm doing pretty well.
Monday: 10 easy (7:01)
Tuesday: 11.2 easy with strides (6:50); deadlifts, core, hip work
Wednesday: Off due to sore back
Thursday: 8M aerobic threshold (in the 5:40s). 13M total (pushed back a day from Wednesday). Treadmill due to icy roads. This went well - it was a mental grind to do it on the mill in the hot, sweaty gym, and I never feel fast on the treadmill. Some people say that a given pace feels easier on the treadmill than outside. For me it's the opposite.
Friday: 8.5 recovery (7:25); core, hip work. Skipped deadlifts to make sure my back was okay; will get back to them next week.
Saturday: Long run - 20.2 miles at 6:40 average. There were several challenging climbs on this route, so the effort was a good bit stronger than the average pace indicates. I was pretty beat up afterward.
Sunday: 7 recovery (7:27)
Total: 70 miles
I'm pretty happy with the quality days and should be able to get back to good mileage in the weeks to come.
The plan for this coming week is a midweek session of 800s or 1000s at VO2 max effort on the track, and over the weekend an 18-20M long run with a good chunk of it uptempo in the second half. Looking for 85-90M total. Three more weeks of general fitness work, trying to address all systems, before I start getting more marathon specific in March.
