I just did a track day and it was fine, even on the drive home. The next morning, I pushed the clutch to the floor, started the car and it didn't come back up. I had to pull it up with my foot. It has been fine since. I have 57K miles on it now, I hope it's not the beginning of the end for the master or slave. It probably needs some new/better fluid.
