that's interesting - are you saying if we focus on breathing we can run faster w/o even trying?

The 2:2 breathing from the start was not something iv tried before. Usually progress from 4:4 3:4 3:3 2:3. 2:2 was enough of a distraction that my cadence increased along with the breathing.

It definitely did not unlock some hitherto unknown capacity for sustained speed. 800@2:59 is not yet in my comfort zone for reps.

Like that you say 'not yet'! That phrase is becoming scarcer in my vocabulary.

Brings to mind a MP and the Holy Grail quote.

I focus on my breathing during different parts of a rep . . . experimenting with similar progressions. I hear the cadence of the breath and it helps me keep my legs moving that fast through the end of the rep. I think.

I can tell my pace by my breathing pattern, eg. 5K pace is usually 1 breath per 2 strides (= 4 steps, L, R, L, R, breathing on the first L). then my sprint pace is 1 breath per 1 stride (=2 steps, L, R, breath on each L). sometimes in the middle of a 200m repeat, I breath every 1.5 strides (=3 steps, L, R, L, R, breath on the first L and last R). L=left foot, R=right foot.
