Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Anyone know anything about this?

I will be removing all references to TrainingPeaks and related trademarks in GoldenCheetah v3.4.1

I realise that for many of our users this will be disappointing. I would suggest, politely, that perhaps you should consider paying for the TrainingPeaks products to get access to them if they are of value to you. I realise many will think this is cutting off my nose to spite my face; that we will lose users. I would counter that this is an open source project that is not for profit and is not intended as a competitor to their tools.

I also realise that many of you may suggest that I am doing this because of my well known dislike of Andrew Coggan. I would counter that I added support for TrainingPeaks and TSS et al long after making public my view of his online behaviour and self-aggrandizement. Further, I was quite happy to port GC to the new TrainingPeaks API, until I realised they did not allow users to access their own data using 3rd party tools.

It is by closing their system to all 3rd parties, limiting download of data to their own tools, that they closed the door to us. I thought the arguments regarding open vs closed systems had long been resolved. Open always wins, Oracle, Google, IBM, Microsoft or more pertinently Saris, Garmin, SRM, Tacx have all recognised the value in being open and benefitted from it.

Here is why we no longer support TrainingPeaks:

1. We do not endorse the "science" behind the terms.
   
   

Despite the furious claims of the originator, there is zero evidence of the validity of TSS, NP, IF, VI, CTL, ATL, TSB and FTP. There are a handful of references to these terms, but no study has ever been published that verifies any of the numerous claims made.

The marketing of these terms has made them popular with amateurs the world over and are considered the lingua-franca of cycling with power. This is because they are promoted in tools such as GC and related. They are not at all widely used by professionals and sports scientists.

1. We did not "steal someone else's ideas"
   
   

I added these to GoldenCheetah in 2010 as many of our users were keen to use them, I did so with permission from Gear Fisher (CEO Peaksware). This permission has now been rescinded and I am more than happy to honour this.

1. We promote real science
   
   

There is no need to use them anyway. There is plenty of science in the literature that has been validated and proven to be robust. The vast output of research stemming from the scientific method is our main focus. Our challenge is to put this science in the hands of amateurs and practitioners in a way they can use them.

1. We value integrity, honesty and openness
   
   

GoldenCheetah has always been an open platform; the source code is freely available, our tools go to great lengths to be transparent and not contain "secret sauce". We are honest about the shortcomings of much of the content of GC. By using these terms and algorithms we have long tainted our integrity. But no longer.

I strongly advise that all users take measures to extract their data from TrainingPeaks before Dec 7th since they have revoked access to ALL 3rd party applications, not just GC. There is no batch export function in their products. Vendor lock-in is a real risk, you have been warned.

Since most users use peakware metrics (TSS, NP etc. etc.) on some level, it seems like it would be a pretty big loss to throw them all out.
