There are existing topics related to this. A few are mentioned in this comment:
Personally I’m not interested because the spread of power within an age group category is even wider than when categories are based on power or score. Plus I want to experience the joy of beating younger people rather than getting smoked by a super fit 50 year old or someone with an inaccurate trainer. There are some existing age group races out there if you want to see what happens in the results.
