![]() This final chart shows some more juicy detail. Perhaps this session was a few 10 minute intervals with some slightly slacked off 1 minute efforts as a teaser? Here this athlete achieved about 83% of his best power output for the 10 minute duration and about 80% for his 50 second duration. Here’s another addition where the current session is looked at in terms of the %age of best Chart 2: Golden Cheetah CP Plot Curve Chart Well that’s the basic version of the chart. It doesn’t say that you SHOULD train at those power-durations but I generally follow the rule that differing stimuli in training are good. Those are power-durations that you don’t train at. You could look at the gaps between the CP curve and the blue line and train to fill those gaps. Set your cycling computer to beep at 406watts (or whatever it is) and off you go. You could look at the blue line and try to limit your power to the power that the blue line predicts you can hold for 105 seconds or maybe 100 seconds as you’ll be going faster and it won’t take 105 seconds, right? The same would apply on the flat. You might know that your favourite hill is 105 seconds long. So what? Well there is a predictive element to all of this. But JUST for the current session, the horizontalish red line, shows that she was working more in Zones 3 &4 – well at least not in Zones 5 and above.If we extended the boundary of those two zones upwards until it met the dotted blue line then we would find that the dotted blue line would predict that she could, in fact, achieve something more like 350w for the same duration.CHART 1: Golden Cheetah CP Plot Curve ChartĬhart 1: Shows the ‘basic’ chart! so for this athlete Something like these 3 charts for 3 different athletes, in fact. for the statisticians amongst you it is derived from mean-max data from your rides. Essentially this lumps together ALL your best ever rides over a given time period and shows your all your best performances as a single curve of ‘best watts held for each time duration’. One of the most useful analyses is the CP Plot – the Critical Power Plot. Even if it’s not for you to use 100% of the time it would be GREAT to use alongside Garmin Connect or SportTracks for times when you want to analyse YOU a bit more. It probably has too much for most of us to use as our standard tool but it has all that a super-keen data-monger would ever need. ie a lot of analysis (Did I say it was free □ ) Like all good cycling rules it will analyse it to the N+1th degree – where N is a very large number. So as I said my old wired trainer is better with TTS4, I like the VR.Golden Cheetah is a highly detailed ( and free) piece of software to analyse your data to the Nth level of detail. Mark the main author is also very active and recently there has been some serious input for some new contributors. I have never designed one myself but it seem pretty straight forward. The sufferfest workouts are all available as are lots of workouts. I plays all of the TACX RLV provided you have the AVI and TTS file. ![]() Its quite easy to get started with but does require some time to get sorted as you want it. Ale (one of the developers) provides better help responses than any IT support I have ever dealt with. ![]() I suggest you join the google group and search for any specific queries you have. There is a ton of documentation on the web with some tutorials but they are a little out of date. I am using the latest snapshot build specifically because there have been some recent changes for my fortius and the training layout screen is being regularly updated / modified. ![]() After saying that the help and response to issues is fantastic. ![]() Supposedly it works well with all the smart trainers. TTS4 is better for this old wired trainer and GC is a little tricky to set up for this model. I use both GC and TTS4 with a Fortius trainer. ![]()
