Toda 10k 2024 - Joy of running above "threshold"

 I probably should save energy for the following week's dreaded cross country race in the Seattle area. 

 
And I don't feel in PB shape.  And I am lazy.  And prefer not to be uncomfortable. 

So I decide to try and run this year's Toda 10k at my recent "threshhold workout" pace (3:55 to 4:00 per kilometer). 

I have struggled with pacing before, but Toda goes perfectly.  

The first 3 kilometers I am right on - just above 4 minutes.  Then at 4k I tuck in behind another old guy and stay at around 3:56 until my final surge. 

To test that I am actually at tempo pace, I do "talk test" at around 8k.   Idea being that if you are in zone 3 above threshold you can still talk, but in shorter, less complete sentences.  I comment on the lovely weather and the wind being less strong than last year's event,  I even switch into simple Japanese (which I don't even hardly use any time, let alone in middle of race).  The guy just grunted in reply.   

Remarkably my finishing time of 39:19 is faster than last year's painful, all-out effort.   I even move up to 5th on the all-time Toda 10k age-group list, and take 2nd in age group.  

As I lamented in my recent post about 5k time trials,  I have been fall off a CLIFF when I try to sustain pace much below 3:50.   It is interesting to see just how comfortable it was to sustain 3:55+ pace for 10k.
