[quote=truckdoug]he4th i am loading all the rides with power into GC, but when i got to the performance manager that chart is blank. is there some set up i must do somewhere else to load data into that page?
and i don’t know what that second question means. i am unaware of any other FTP viewing than looking at my CP chart and that little dotted red line[/quote]
I googled for the formula to calculate starting LTS (aka CTL) which I don’t recall exactly, basically the number of hours you ride for the last three weeks divided by 7 or some such. The third or fourth link was “training superthread”. I lol’d. There was a whole lot of “Dr. Wikipedia” which made it even funnier.
Doug, do this: Go into GC and look in the preferences menu. If you’re on Mac OS, this is in the “Golden Cheetah” section on the menu bar up above. Click on “Athlete” and then select the “Power Zones” menu. There you need to add your CP with the from date of your earliest ride. We’re going to assume that CP (FTP) hasn’t really changed much since you started. From this point forward, getting CP and the “from date” correct for where you’re at is crucial for performance manager to be accurate. You need to re-test FTP every 6 weeks or so. Assume you set your CP now, and you go in and set a new CP in 6 weeks, if you don’t get the “from date” correct it will re-calculate training stress to be lower for all your earlier rides. Also, this field will get filled in by the “save CP” button on the critical power chart. You don’t want to update your CP very often as it’ll throw off your performance manager. If this doesn’t make sense to you now, don’t worry about it. Just set your CP and we’ll revisit it then.
Once you have your CP set, you’ll see data in the performance manager chart. Now is we need to estimate your starting LTS. You’ll have to recall how many days per week you were riding before you started collecting data. Let’s assume you were riding 5 days per week. Look back through your data and pick a ride or three that is similar in terms of length and intensity to the ones you were doing then. Say, one 3hr group ride, and a few other rides of various length and intensity. Get the bikescore from those rides and divide that by 7.
Say you had two easy rides at a 30, a couple of mediums at 70, and one at 150 given you a total stress accumulated in that week of 350, divide that by 7, and that gives you a stress score of 50, which you can use for starting LTS. Typical starting LTS scores are 30-50 unless you were training a lot. Alternately, just tell me what an average week looked like before you started training with power and I’ll estimate a number for you.
At this point, you want to go back to the preferences menu, select the athlete, item, then select the “performance manager” tab and put a number in the “starting LTS” field around 30-50 as I described. Then close that window and go back to your performance manager chart and you should see numbers for STS, LTS, and SB. Once that’s all established, we can work from there.
To write out this wall of text, I had to install GC and load some data. Now that it’s installed, if you’re inclined, you can start emailing me your power files. I can load them, check your work, and give advice as necessary.
