This depends on how well you are handling the build week training loads currently and how well you want to perform on the hut to hut trip. If the over all load in Luke’s plan is quite tolerable then you may not need any taper and can roll from a build week right into the hut trip. If you’re worried about feeling fresh for big ski days with lots of train breaking I’d suggest a short taper before the trip. Perhaps not the whole week but certainly 2-3 light days. As for after the trip I definitely suggest a light week. At least for 3 full days after you get home. It has been my experience that after a big over reaching week, like we often do in focused training camps with athletes, the residual fatigue does not surface until Wednesday following the final day of the camp on Sunday.
I blame endorphins for masking the fatigue although I don’t know if it is true or not. Just be cautious of jumping back into training where you left off. It could well be that you need a full week of recovery post hut trip
