I’ll post more later, but the consensus of most people on the forum is the 2000m of short speed is WAAAAAY too much for mere mortals who do not have the therapy budgets and access that Charlie’s athletes have, in addition to the stress of any other obligations. Many people have adapted it though with a ride range of volumes (I have seen anywhere from 600-1500 or so a week) with great success. 2000 though is a bit out there for most of us.
