Yeah, unless you really abuse the clutch, it should last for 100K+ miles without any troubles. You will know when it starts to go bad. When the clutch wears out, the engine will "free-rev", when driving. When the clutch is engaged and you step on the gas, if the engine revs up but the car doesn't gain any significant speed, your clutch is probably shot. Also, like PA_MP3_Man said, if your clutch slips really bad during a launch, it's probably time for a new one. I had a clutch last me about 105K miles in my RX7 before it started to give up the ghost. I also used to autocross and drag race it periodically.
