    Calculating FTP

    Wow, now I know why I don’t bother to post anything. To answer some of your comments - I try to remember to calibrate power meter before every ride. Did I on this one? Can’t remember but probably. When doing the FTP test, for sure I didn’t pace it right as I went out too hard. It was my first attempt. Ave power would have dropped by 30w in last 5min. I have always ridden with a low cadence in training and racing of around 70-75. I did the test at 90 cadence as that’s what I read you should do it at. I run around a 3:30-3:40 IM run off a 4:55 bike at 77kg. Is that good? No idea. Is that relevant? I only put that in to give some background into what I can ride (course dependant) in comparison to what my FTP test came back at to see if it was low or not. The question I was trying to get across was how to get an accurate ftp figure when riding outside you see big differences in perceived effort and heart rate for the same power output that you do on a trainer.

    Calculating FTP

    Ok so recently got my first power meter. Did a 20min FTP test, and after the calculations came in at 254. My initial thought was that this was low (maybe I watch too many YouTube hero’s bragging about their FTP’s) as I have rode 4:55hr IM bikes 3 times and would consider myself in solid bike fitness shape when I did the test. Anyway my question is, I did the test on my indoor trainer and went flat out - HR was maxed out cadence around 90rpm and I faded a bit in the last 5min. The other day I was riding outside on a flat road into a head wind and was easily holding 350 watts with a cadence around 75-80. I maintained this for around 12min before turning and picking up a tail wind. Before turning I wasn’t struggling and felt I could easily hold it for the 20min. So which way should the test be done? With both these scenarios FTP result would change by about 80 watts. I find my current FTP of 254 works well on the trainer and produces hard workouts, whereas riding outdoors sessions are a lot more comfortable at the same wattage efforts.
