yes, i guess that's right. but obviously the pace-HR connection depends on a lot of things, even within one person. anyway, i will not get too bent out of shape about it.
- SubT 3 x 10 mins
-- warm up (including 3 x 100m strides)
-- intervals @ 4:16, 4:16, 4:15 w/ 60-75s rest
-- cool down
again just resting until HR gets back down into the 120s, seems more than adequate for this workout. pace was on the quicker end for what lactrace tells me it should be, but RPE 6-6.5. ¯\_(ツ)_/¯ it was beautiful out this morning, which obviously helped after the heat and humidity of the last week. i will take it extra easy tomorrow because 17+ km followed by today's longer-than-usual workout means i should be careful about load.
the friend who i did the trail run with the other weekend came and did the first couple sets with me and then shifted to 400s. he's trying to break 5:00 in the mile. ran 5:01 a couple weeks ago. pretty quick for early 40's!
