I achieved a new threshold power today during a Zwift Race. I was scheduled to do an FTP test this coming Tuesday with the of start SS2.
Should I do another FTP test Tuesday or begin SS2 with my new FTP?
My previous FTP was 272 at the start of SS1 and my new FTP as of today is 297. I am also lighter by about 4lbs since my last test so needless to say I’m super happy with the increase!
I would recommend you just go with the number you achieved during todays Zwift race. Since you are have sweet spot 1 and sweet spot as separate plans they do have you starting off with a field test but testing every 6 weeks is not necessary. We have a podcast on using group rides and races to help determine if a new FTP has been achieved. That is basically what you did today!
And to save Frank from having to chime in I’m pretty sure there is not a Zwift race in the sweet spot 1 plan.
