I haven't figured out optimal sequences, but would assume that lower key
volume is more easily obtained with classical. For most of us,
conditions help determine this, since early snows tend to support
striding, even if it's only trudging around.

the pacing, the ebbs and flows of classic intensity tend to be more

overall.

Your thinking seems about right to me. I'll try to check this out with my
HR monitor by covering the same kind of loop alternating techniques, going
as hard as I can. I wonder, then, whether there's an optimal classic-skate
training sequence as in early season training doing classic, in terms of
core strength, and later, sprint and interval, training doing skating.
