14 hours a week so far, riding every day. Yesterday I hit a pretty damn high avg for my 20min effort, with the last two minutes jacking it up for another 40w. Only doing that once or twice a week, the rest is LSD and tempo. Hope to be able to roll a 25min TT at 320-325 this spring.
My 20min average is below DrWJODonnell's tempo, though. That makes me sad.
