A great feature (maybe something like this already exists and I have not found it yet) would be to select a custom date range and view the classification/intensity distribution over that range.

Awesome, I was really hoping this was how it works. I could not find a tool that nicely showed polarization over weeks and this does exactly that.

Hey David I accidentally stumbled accross intervals.icu on the Trainerroad forum. I absolutely love it! I have a question regarding the weekly classification (base, polarized etc). I don't use a power meter on my outdoor rides. Does iicu use my HR to determine the classification of the estimated power curves from strava? Thanks David, you built something really useful!
