Historical FTP Record


(Aaron) #1

There should an easy way for users to access ALL of their historical FTPs, whether achieved through specific FTP tests or identified by Zwift during a ride.

Users should be able to plot their FTPs from current all the way back to their first FTP measurement and be able to see in what context that FTP was achieved - specific FTP test, in-ride identification, etc. thereby analyzing how / when their FTPs were achieved and the trend over time.

This functionality should be one that is VERY EASY to use and not require downloading hundreds of rides into a 3rd party program and somehow mining out the FTP result from each ride.

Sounds basic and should be be part of the subscription package.

Help Zwift please.

I don’t want to sound rude, but if you first get some knowlegde about the concept of FTP then you will understand that this requested functionality is of no use.

It would be good for validating e-racing results though.

Tracking FTP over time would be useful. Why do FTP tests if historical results are of no importance. Why focus on improving FTP if historical results are not important. It would be a very beneficial tool for those wishing to see how their training is progressing.

There is not such a thing as “in ride identification of FTP”. An FTP test is done with a certain reason following a certain protocol. Only those values with the same protocol can be compared with eachother.

Furtermore, you don’t do an FTP test that often. Some trainers may say once every six weeks, but most of us do it max a few times per year. Also and not quite unimportant, you need to be free of stress in your muscles of any effort you did in the days prior to an FTP test.

Don’t put too much focus on FTP, it is just a number to set your training zones. It may vary easily like +5 of -5 just because of how you feel that day. It is not that important. Take it on an higher view and take a look of your year-by-year progress or half-year. What’s in between is not that important.

For most cyclists there is more than Zwift alone and Zwift only keeps track of your rides within Zwift. Just looking at the numbers (in the winter period) within Zwift is a very limited view of all of your data.

The main cause of this discussion is that Zwift makes FTP very important in their category system to distinguish the various levels of riders. And they implemented this “Hurray, an increase of your FTP is detected” screen which is quite funny for me to see.

However, I agree with John Poole some measurements can be used to validate efforts by riders if the values for power actually match their previous efforts. But then you should still be very carefull since you never know the context of a certain ride.

Trainerroad of course has this ability. In the attached graph showing the last 4 years of training the diamonds are where my FTP changed. I can select the workout (if any) where this changed occurred. Another page lets you delete the FTP changes. This is handy as you can manually change your FTP in addition to doing FTP tests where the test will update your FTP (if you want it to).

My advice is if you’re serious about your training then do what quite a few of us do and that’s use Trainerroad in conjunction with Zwift. Zwift mainly being used for entertainment and social stuff.

Just skip waiting for something which is easly managable fitting into the code and download this one instead:
https://www.goldencheetah.org/
Guess what, its for free …


(Aaron) #8

Perfect. Thank you.


(Alexander Perdon (CTWT)) #9

Like I said before…+5 -5…No big deal.

But 2 FTP changes on one day… and 2 over 2 consecutive days… and 3 over a span of 6 days…that’s some work!! :wink:
ps. Don’t be offended but this list can’t be taken seriously.

This has nothing to do with FTP, but probably more as a list of 95% of your best 20 minutes during a ride. That should not be considered as your FTP…


(Alexander Perdon (CTWT)) #10

Golden Cheetah is a great tool but the downside is that it is all offline and you need to import your data manually.

I prefer TrainingPeaks instead. It is not for free and not cheap but it is a great tool. Also most apps do have an upload function to TP.

My training truth is both in TP and Strava and I use Veloviewer as an extra utility.


(Aaron) #11

Thx for all the comments and tips.


(Gerrie Delport TeamODZ) #12

Yes it is off line (that part I like) but you can set up a default directory to go find your .fit files, I have my set to Zwift/activities so all my zwift stuff get uploaded when I open GC.

I also use Strava , Garmin Connect and Sportracks (Sporttracks is manual import but I have been using it for the past ±15years).


(Mark) #13

GoldenCheetah 3.5 (dev) will sync with all the main platforms that provide an open API.
This excludes TrainingPeaks, but includes Strava, Xert et al


(Alexander Perdon (CTWT)) #14

Sounds great, but will GC be available in the cloud?

Anyway, if I would install this version and start from scratch then I will get a complete history of my activities in GC. And that would be cool.

I have never had an FTP increase in Zwift. I am currently at 277. I did a TT the other day that took me 35 minutes to complete, with an average wattage of 290. Wouldn’t my FTP have increased? Do you have to do an hour ride or some other minimum amount of time for an FTP increase to take effect?


(Paul Allen (Watopia Wayfinder)) #16

Yes, I believe the ride must be an hour in total for your FTP to increase.


(Umsiausias) #17

No the ride does not have to be an hour in total. My last FTP increase happened after a 44-minute ride.


(Kari) #18

It seems to me that a 35 minute ride at 290 might not give you an increase to your current FTP of 277.
Doing the 20 minute FTP test at 290 would definitely give you an FTP lower than 277 so I am not surprised that your 35 minute ride would do the same.


(Gerrie Delport TeamODZ) #19

Correct. FTP calculation for a 20min effort is 95% of Average Power (W)

thus. 290w * 0.95 = 275.5w


(Brad) #20

Ok, I misunderstood the calculation for the FTP. Now I understand. Thanks everyone.
