I know, yet another FTP question… but bear with me. I searched quite a bit and read many many FTP threads, but somehow didn’t come across this particular question/situation, which I thought odd since I imagine this might be fairly common. Anyway…
I started structured training for the first time ~ 18 months ago, in a 2-day a week (1 hr each) cycling class that uses computrainer equipment (wheel on) and software.
Around the same time, I bought a Hammer H2 for home, intended mostly to supplement my training, and hadn’t used it all that much (maybe 10-20 times) until the recent lockdown. At home, I typically use TrainerRoad. Since March, I’ve used my home setup much more frequently (probably averaging twice per week).
In my cycling class, we do 20-min FTP tests every 6-8 weeks. I never did a different type of FTP test until recently, when I did a ramp test on my home training setup on TrainerRoad in June. When I did that ramp test, it gave me 235 as my FTP. I felt like that was pretty low since my workouts in my class on the computrainer were feeling pretty easy and were using 230 as my FTP (from my prior test earlier in the year) and I thought my FTP had gone up a good amount. When I did my next FTP test in the class a couple weeks later on the computrainer, I came in around 250 and I actually thought I undershot it (could have gone harder, didn’t feel like puking afterward, which is how I usually feel).
I can chalk it up to different trainers, different type of tests, different software, etc. and that is ok.
So, my question is… should I maintain 2 different FTP values, one for each “environment”? i.e. keep using 235 at home on TR, and 250 on the computrainer. And just maintain the separate tracts?
Or should I “force” a reconciliation between the 2 and use 250 in TR at home (or some compromise value)?
