I had an off biking year too.
2007 I rode 3500 miles. 2008 only about 1700 miles maybe? Yikes, less than half!

The winter had icy slushy roads a lot, and I got several long colds.
Then in the Spring I hurt my hip and was off the bike completely for 6 weeks.
Then this summer and autumn we have had more work load than usual (not complaining about that, for sure).
So it's just been a really off year for riding for me. I am still riding regularly and enthusiastically though, just fewer miles per week.
