Before I installed a computer, I estimated my distance based on time-exertion, and cadence. I simply estimated how far I would have gone on my average outdoor route at a given exertion/time/cadence level on the trainer. Then I subtracted 10% just in case I was overestimating.
Once I installed an old computer on the trainer bike, I found my estimations were reasonably accurate. But it's still a rough estimate.
