@theflyingduttman awesome man, congrats! If you did this WO above, and ranked it Moderate, your FTP is pretty much bang-on, as a starting point. Now you’re off to the races, you can keep smashing WOs outta the park, and Adaptive Training and AI FTP Detection will do their thing.
Just do keep in mind that for some riders AI FTP can push too aggressively high.
One of the most important things I learned early on was: Especially before you know what TR’s gonna do to you & your recovery system, your WOs should be Mod - Hard. One VH / wk is OK, but not ideal.
If you class >1 WO in a wk VH, or even one AO, your FTP is too high. [More advanced users may learn their systems can tolerate >1 VH every week, and continue to show up ready to rock the next day.]
Strongly recommend using THE CHART OF DESTINY!!!
