I'm now using my commute as training, not just commuting.
15.87 miles over rolling (long) hills with some slow upgrades as well as fast downgrades. And you know about the Monster Hill.
Yesterday I did the whole trip in 59:57 (rode the hill), and was I ever thrilled! Average speed 15.9mph. WOOT!! Previous record was 15.7 average, but that was with a tailwind.
I've been working on leg strength by keeping my gears higher on the uphills. Yeah, I'm gear-mashing, but it's not like I have to save my legs for the run. I'm working on making the hills harder and making it up them. SavageMan is coming.
