Now THAT'S perseverance! Wow!
Do remember, though, that although your brains remember how hard and how long you used to ride, when you haven't ridden at all in two years+, your bodies no longer have that capability. For now, only ride as long as it's fun, and when it quits being fun, go home.
We recently had a year almost completely off the bikes, and to get started again meant 5 - 10k rides. Within a month we were doing 40 - 50k, but we're two months back on and still not ready for 100 or 150k rides again.
YMMV, but do remember to be easy on yourselves. And have fun!
