Two kids and a wife that's clinically addicted to my espresso. I'm an early riser (5:00-5:30ish) and get in 17-18 miles before they wake up. On days that my wife has off (she's on a 4 day/week schedule), I'll take longer rides.
I know that a lot of people hate to get up early, but it's cooler in the summer and there's *so* much less traffic to contend with.
