However, when examining the potential for going super -TSB post-ride, it's useful to consider FTP and the advertised w/kg of the ride and how terrain may play into your PD curve. Manipulating CRR and CdA through equipment choices and/or adjusting pack position can allow for sufficiently less FRC-type efforts, just as staying OTB could provide a bit more stimulus if needed. Ultimately, if your plan on TP calls for Z2 but your IF is 1.1 with an NP-buster type ride, you've probably overdone it.
