As the air is cooling I’m beginning to think winter and xc (nordic) skiing again. 
Has anyone modified a Triathlon plan to use for Nordic skiing? Or have thoughts or feedback on doing so?
I used Plan Builder to map out a mid-volume plan that begins in early November and wraps up late June for my A event, a 140 mile / 9,000 ft gran fondo. But, by the time I layer in anticipated runs and xc skis I’m well into high-volume territory and I know honestly I won’t have the capacity (time & will power) for that volume.
I’m thinking of trying mid-volume triathlon base and build plans through early March (ski season), but swapping out the swims for dryland training until the snow flies and then swapping out the swims and some runs for xc skiing once there’s skiing. I would drop the brick workouts altogether. This still gives me 3-4 bike sessions a week while accounting for runs, skis, and a rest day.
Come early March I would transition back to a cycling-focused MV plan.
I am thinking something like this:
Nov - Jan (8 weeks): MV 1/2 Distance Base - 4 rides / 3 runs / 3 dryland workouts
Jan - March (6 weeks): MV Olympic Build - 3 rides / 1-2 runs / 3-4 skis
March - April (8 weeks): MV Sustained Power Build (or LV + outside rides)
April - June (8 weeks ): MV Climbing or Rolling Road Race Specialty (or LV + outside rides)
Or… am I really overthinking this and would I be better off by just rolling LV bike plans and then adding on the runs, skis, and outside rides time and weather permitting?
For what it’s worth: Up until now I’ve only done LV plans, but in addition to the workouts I was getting in 2-3 outside rides a week and had my six-week TSS average up to 520 TSS a week before my A event was canceled and I dialed down my training.
