Good thread!!
A quick glance at Strava says I did 19,501.8km (12,038.15 miles in old money) in 671hrs.
That's not including turbo/roller sessions or track work, I've only recently started recording those on Strava.
Best month was August with 88 hours clocked, worst was January with 26hrs (although that's not including track).
Given the quality of the summer we had that will be hard to top bit a goal for 2014 must be to at least equal it!
