Newbie here- thanks a lot for a very useful learning portal!
I’m involved in training and planning for junior mtb’ers (16-18 yrs olds) on a national level. Most do cross-country skiing half of the year (and gaining a lot of high intensity work) , and converting to cycling as the spring arrives and further towards the mtb racing season (late april to september).
I have taken great interest in the different pathways at the site, and understand the broad focus towards low intensity volume traning for long term best performance. But, given the fact that building the highest possible vo2max is something that is optimal before the early 20’ies- my question will be how to prioritize the available training time for junior athletes? One possible approach might be to crack on with lots of vo2max work (and appropriate rest) and reduce training volume, OR keep focussing on the low intensity volume work for building this strong fundament. Of course, both is desired, but with a limited time for training (school+++), is there any advice on this from any of you?
