Personally, it now hovers around the 82 - 84 inch mark, for commuting/training around London and Richmond.
47x15 or 49x16, depending on which bike I'm on.
I've done 6 London to Brighton's, plus London to Oxford's on fixed, using ratios from 73" to 84", usually 79 - 84 inch. Even went up Ditchling Beacon an a 84" fixed ... those fat poser guys walking their £3K carbon, full-suspension mountain bikes up Ditchling looked really pissed when they saw me zig-zagging/grinding up the hill past them :)
I used to live in the countryside many years ago, in very hilly territory, when I first ventured into fixed/singlespeed, I was then on 67 to 73 inch, cycling for pleasure.
