Having said that, it's easy to overdo it with longer rides and 100km seems like the longest distance that makes sense to me on a regular basis.
As always, ymmv and working up to numbers like that may take some time.
I think we all have our set points where our gains are going to be outweighed by our losses, and that it would vary a lot from person to person. I can't even imagine riding a 400 km day, although I've come pretty close to 300 (270 km). I'm sure there are factors like body size, age, etc. that are beyond our control that would have an effect on our maximum potential.
