• Anyone know how to estimate W'? And for any Golden Cheetah users, how does it calculate this? Just done a 20min test and it says my W' Expended (%) was 237 which makes me think it has woefully underestimated mine. In its model for this month it's 13.7kJ but in the past its been over 30?

  • It's it's any kind of help, I did a 20 min ftp and got these numbers
    Average Power (watts): 261
    Average Heart Rate (bpm): 171
    Total Work (kJ): 313
    Total W' Work (kJ): 20

  • I just use the estimated W' value provided in the CP chart in GC.

    I don't know how to actually test for W' but I imagine that having a fully fleshed out CP curve helps. I'm in the same position as you... last 10mile TT I spent 167% of my estimated W' suggesting that my current estimate is low.

    I'm not too sure an exact figure really matters. My only real use for W' is the W'bal chart which can give you a good idea of how well a ride or interval was paced.
