I'll admit, I "feel" stronger with higher CTL, but that's usually when I have done some combo of lots of endurance and sweet spot, so it's only one kind of "fitness" (as we know ctl often gets called fitness but it's a misnomer since it's really a training load measurement). But it wouldn't be the type of fitness I'd need to race CX. So my CTL will be lower for CX season but I'll be doing more of vo2 and anaerobic to be race fit.
I think TR have really got this well sorted now. I don't actually use their platform, but I do follow their podcast with interest. What they are doing here makes a lot of sense to me.
