7/29 outdoor easy run
Planned: 3.0 miles @137-152bpm (13:13/mile)
Actual: 3.99 miles @ 141bpm (13:34/mile; 152 T+D; 12:55/mile adjusted)
Negative splits, baby!
I spent some time yesterday adjusting my pace targets to help me control my start speed. I settled on a 13:13 target for my Easy Run, or 13:53 adjusted for T&D. My goal was to target that pace for my first mile, and then hold or increase that pace for subsequent miles.
I still came out a little faster, but much closer to my target. I was able to slightly increase speed in subsequent miles while staying in my HR target range. My GAP was actually shockingly consistent across all 4 miles.

I may have cut it a bit too close in that last mile, but overall it was a much more consistent outing and a successful experiment.
I have updated pace targets across the board now, based on trying to map recent runs against my HR targets.
I've assumed my Easy Run pace should be ~9.5% slower than my Marathon pace, and my Long Run pace should be ~12.5% slower. Working backwards from my actual in-range runs, I get a marathon pace of 11:45.
From there, I extrapolated other race paces based on relative distance (with a 1.06 exponent, or 1.08 for 5k and shorter). This seems to be what @DopeyBadger's calculator does, along with other similar resources I've found. For 'Tempo' I just took the midpoint of the Half-Marathon and 10k pace.

I filled in (T&D adjusted) averages from my last two Tempo runs, for the 1 mile (the first-mile pace of the two runs) and the 5k (extrapolating the 2.25-mile and 2.5-mile runs out to 3.1, assuming a 15% slower pace for the remaining mileage).
Interestingly, I found that my speed at these distances was a good bit faster than expected, even though they were not all-out efforts. That seems fine -- I'm still focused on HR targets, and primarily want to use target paces to control my 1st-mile starting pace before adjusting. It may mean that my anaerobic fitness is greater than my aerobic fitness, and have good potential to pick up speed as my aerobic fitness improves. The effect could evaporate in a few months when this extreme heat passes (T&D > 150 every single run for the past two weeks). Who knows?
The one thing I'm not sure about is how to evaluate whether my Tempo run is too fast. If I go purely based on Zone 4 heart range, I'm right where I should be. But that may not actually be where my lactate threshold is? The runs don't feel too hard. But I should probably do some kind of test to figure that out.
And Now For Something Completely Different
I'm used to being passed by bicyclists on the Blue Line trail, but this was something else.
