Hey - would I be right in thinking that I could substitute for e.g. a 4hr endurance training ride with a similar length of another activity (e.g. Ski Touring) - assuming I look to keep to the recommended HR zones (2) etc.
On top of that - it’s pretty hard to go for a 4hr ski tour without getting to the top of the mountain - so I would also be splitting the 4hrs into 2 or 3 pitches during the day. I would assume that that is also fine?
There are other longer rides in the plan that include a few Z4/5 short efforts - again if I did this on the skis I would assume it’s mostly about getting the HR up briefly before settling back into Z2.
(I live in a ski resort, so pretty much locked to 4hrs riding on a trainer or no riding at all - at least for the next 6-8 weeks or so)
I’m training for an event in the Summer, so will be able to get plenty of specific bike training in as the event nears.
