Hi Brian,
I’m definitely not an expert and I would like to see the input from some of the coaches on this. I’m wondering if this is just a “specificity” re-adaptation that takes a bit of time. What I mean by that is, maybe by now your body got so used to running that it might take a bit more that 8 days of skiing to “fully” use that aerobic engine you built running to the new demand.
Are you still keeping a high volume of running outside of the skiing workouts?
Hope I didn’t make it more confusing 🙂
