I’m fortunate (or unfortunate, depending on your perspective) to live in Minnesota, where winter is literally 6 months long. I’m not a winter cyclist and fat bikes don’t interest me, so I use XC skiing and SUF to stay fit/keep off weight/maintain sanity.
My question is about intensity: XC skiing (especially skate-skiing–which is what I mostly do) puts me at Threshold HR or above pretty consistently, which means I can’t go very often or very long (typically under an hour).
I’ve been doing Sufferfest for a couple years now and really enjoy it. Overall I’m riding ~4500 miles/year (including indoor rides) and feel fit and competitive even at 53 thanks to the structured training plans and I don’t want to mess things up.
However, I’m wondering if whilst doing a plan I could substitute the “intensity” days on the bike with XC skiing to get myself out of the basement 2-3 times/week. Then pain cave days would be longer endurance efforts and/or technique (cadence, etc.) plus strength training/yoga.
Interested to hear other “frozen chosen” folks on the pros/cons of this strategy.
