source code for calculating fitness age/ fitness page

Hello,
according to the manual (e.g. https://download.tomtom.com/open/manuals/TomTom-Fitness-Age-UM/refman/TomTom-Fitness-Age-UM-de-de.pdf) I should be able to obtain the source code for the fitness age.
Where can I raise this request?
How can I contact the support or obtain the source code?
Looking forward to and constructive feedback.
many thanks & best
Claus

    The link you give does not work and TT never gave out the source code and never will. It is a proprietary algorithm and frankly is not very good anyway. It uses your calculated VO2Max (which will be wrong as no watch can compute this) to calculate points and it only uses runs or cycles. It is not the amount of exercise that matters, it is the intensity. Unless you are in Z3 or higher for a substantial part of your workout it will not change anything. If your workouts are walks or jogs or anything that is not intense, it will have no impact on the age and points. It is based on whatever algorithm TT came up with, which is different than what Garmin uses or Strava uses, or anyone else. I honestly don't feel you can make any judgments from what it is telling you in terms of fitness points or fitness age, it seems to be a random, capricious measure that ties to very little. Ultimately, I don't expect a watch to be able to tell me how fit I am.

    Many thanks for the prompte reply. Sorry for the issue with the links.

    A shortend version of the link to the Geman manual is: https://tinyurl.com/25zjhjuv

    However in the english manual (https://tinyurl.com/4ppshmkj) it states on page 24:

    “Open Source Software The software included in this product contains copyrighted software that is licensed under the GPL. A copy of that licence can be viewed in the Licence section. You can obtain the complete corresponding source code from us for a period of three years after our last shipment of this product. For more information, visit tomtom.com/gpl or contact your local TomTom customer support team at tomtom.com/support. Upon request, we will send you a CD with the corresponding source code.” (end of citation)

    English is not my mother tongue, but to me this implies TomTom is willing to provide the source code. But so far I can not reach any support of tomtom.
    Any idea how can I file my request to the support?

    It is a moot point as TT Sports went out of business almost 4 years ago and discontinued all products at that time so the 3 year window is up (and it likely would only have been valid if they were still in the business anyway). There is no more support for these products, they are obsolete and past end of life. What are you hoping to get out of it? What good does having the source code for an obsolete product (and I highly doubt it is the source code for the entire watch without being heavily redacted) get you?

    Sorry for the very late reply - I was completely booked in two other project with heavy deadlines.
    To answer your question: I would like to get an idea what they did to get an understanding for their calculations. To me the results do seem pretty surprising.
    Sorry to read they are out of business, but the code might be still of some interest. If it of no interest for them anymore, why does the mother company not provide it (e.g. via github)?
