My first was a cervadil/pitocin induction, so not reliable data at all.
My second was about 10.5 hours, total.
My third was about 6.5 hours.
(My second, though, was at a hospital nearly an hour away, and I suspect that whole driving/triage/getting settled process probably added some time to it. My third was a home birth without any sort of interruption. My labors *felt* very similar, even though the second was considerably longer, and I suspect they would have been more similar in duration if the circumstances had been more similar.)
