Blog post mentioned in this super fast pod: https://www.evoq.bike/blog/2019/1/25/1-massive-reason-why-obsessing-over-your-ctl-can-ruin-your-race-season
Quick bits:
-CTL doesn’t know how tapered or rested you are
-You could do 100 TSS a day from zone 2, or 100 TSS from a 1 hour time trial; you'll feel very differently but same CTL!
-You can consider TSB, BUT you could be at 0 and be exhausted…this can happen after a big spring build up (see blog)
-TSS accounts for, but doesn’t highlight or differentiate things like: Intensity, Repeatability or Race Specific efforts.
