At the beginning I was thinking it was impossible too, but little by little, knowing the segment, I get some.
I'm 48 with family too, but with a rather flexible job...
Unfortunately for you, bike greats probably love to train in the Alps, putting the bar probably higher
One example of my recent Strava fights:
Someone makes a new segment on my routine-before-work track(~20km I do twice a week).
I'm 10th with something like 2:00 or so.
At my next morning ride I push more and win the KOM.
The same evening the guy get it back, putting me 24" behind...
A couple of days later, I take it back, not far from throwing out my lungs at the end.
The same evening! Damn commuters...
he put me 6" behind.
I gave up for now, rain left the track quite bad and impossible to compete.
It is definitely like a video game.
