I currently have three main routes:

My commute this morning (half hilly minor country roads & half major A road) was 14 miles in.

My commute yesterday was 13.5 miles in (80% hilly country lanes, 10% converted railway line, 10% main & suburban roads of varying levels of traffic).

My commute on Friday was 13 miles in (60% hilly country lane, 30% off-road (bridlepath through woodland) and 10% main & suburban roads of varying levels of traffic).

Oddly the longest route is the quickest of the three by a god 10 minutes....

I've yet to be brave/stupid enough to try the most direct route which would only be 10 or 11 miles as almost all of it would be along the A 2 (M) (the M2 stops at Faversham, turning into what is supposed to be an A road to Dover, going past Canterbury - trying to distinguish the A road from the Motorway is not easy, and as it's got a nasty hill halfway between Faversham & Canterbury I've avoided it).

Homeward I currently cycle a mile to the station, and a mile at the other end. I'm planning to cycle both ways sometime earlyish next year.
