9/29 -- 3 x 2km split intervals

 Repeat of last week, this time trying to back off and actually run threshold pace. I don't have any good way of gauging pace mid-interval, so each 1km stretch is done by feel. I did think I backed it off successfully, and tested myself by saying some short phrases between breaths. I also didn't quite nail the pacing goals, which were 3:56-4:00 / km. 

 The bike trail was damp, with many sticks and leaves down. Footing wasn't terrible (except for the turnaround, where I almost wiped out on a mudslick in the first interval). All the same I would estimate conditions were ~2s /km slower than last week. 

 7.75mi total. Did 4 grass striders to loosen up beforehand. 

Interval 1: 3:54 / 4:04  (7:58)

Interval 2: 4:02 / 4:06  (8:08 ouch)

Interval 3: 3:59 / 3:59  (7:58)

Jog rest ~110s.

9/26 Long Run + Tempo

A nor'easter blew through our patch of Massachusetts this weekend, bringing heavy rain and some wind. Fortunately the rain hadn't begun by early Saturday. It was one of those eerily quiet pre-storm mornings, fully overcast but with an unusually high cloud deck. Somewhere up there were the storm's furious winds, but down in our valley it was calm, damp but rainless. Early morning sunlight shown horizontally beneath the clouds, giving the forest a faint blueish tint. 

 The run on the menu was another 14 miler, similar to last week, but adding one more mile to the tempo section. I could not get what felt like an accurate read on the gps watch, which I think could be explained by all the turbulent clouds between me and space. I didn't quibble about the 9:30s it claimed I was running, since I felt strong and I'm sure a little extra distance couldn't hurt. 

I decided to pace the tempo section by feel: 28 minutes @ half-marathon pace. I noted landmarks as best as possible with the hope of reconstructing my route in google pedometer later to get accurate distance+time. Almost all the tempo was done on bike-trail, with just a little bit along roadway at finish.

SPLITS

  1.  0:00   START (est 2.5mi from roundabout. I passed a sign "2.4mi to roundabout" 56s in). 
  2. 17:08  ROUNDABOUT
  3. 28:00  FINISH  (1.56 mi from roundabout).   

 Distance from roundabout<->finish is pretty reliable, because both were easy landmarks. That works out to 6:51 pace on the first stretch of bike trail, and 6:58 pace on the 2nd stretch. I did start fading on that final section, which was mildly uphill compared to the mild downhill leading into the roundabout. 

All in all a good effort, with no particular nagging pain. The tempos are certainly helped by all the nearby bike trail, which is very straight and flat (even that mild rise in the 2nd split above barely counts as anything). But the Newburyport is not reputed to be a very hilly half, so hopefully it's good race specific training.

7.5mi, 3 x 2km repeats

This was originally 3 x mile in my plan, but my safest route was a 1km unbroken stretch on the rail trail, so I modified it to be 3x 2km (really 1km,1km, with 0 rest in between, to factor out the u-turn). To account for the longer interval I gave myself slightly more generous rest (100-110s, rather than 90s). 

I felt strong and a little south of max effort for the distance. Conditions were ideal, with temps in the 50s and no wind. 

6 x striders on grass, then:

2KM split intervals

 3:44 / 3:58

 3:47 / 3:57

3:53 / 3:49
