No kids yet, although that's about to change in a few weeks. After that I suspect the volume will not be quite the same. I am already doing a decent amount indoors (Saris H3/Zwift), so that should help me scrape some bits and pieces of fitness during the early months/years.
But up until now - I'm mostly a train in the morning before week kind of guy. Typically 12 or so hours average, but that includes a lazy period in late summer through fall, and some weeks pushing up towards 20 or the high teens in late winter. That takes some midweek PTO or time off work to happen.
