  1. Hi

    Will two riders with different FTP get the same TSS if they ride for the same duration and with the wattage relative to their FTP?

    So if both riders rides 2 hours at 70% of FTP, will they have the same TSS afterwards?

    Yes

    TSS = (NP/FTP)^2 x hrs x 100

    So provided both riders had an NP for their 2-hr ride which was 70% of their FTP, then they will both attain a TSS of (0.7)^2 x 2 x 100 = 98 TSS

  3. Great, that's one thing about power, I think I understand then :-)
    Thanks for your reply
