I'm getting ready to build a new race wheelset...King/3.1...and I'm concerned they won't be properly broken in if I begin racing them in February/March...Anyone have any experience with the amount of time it usually takes to break in these hubs??? I've heard it takes time...but, I don't want to damage them in the process.....

From the owner's manual
Break-In
Once your new hub is placed in service, some settling may occur. Check adjustment
by clamping wheel into frame with the quick-release. Ride for 5-10 minutes,
check for play or binding, and readjust if necessary. Recheck after the first 5-10
miles of riding. Check cog lock ring on rear hubs after the first 20 hours of use,
and tighten if necessary. Continue monitoring for the first 60 hours of use.
During the first 60 hours of use, above average amounts of drag may be noticed.
This is normal as the seals break in, and will soon diminish. If this causes chain
sag in the rear while back-pedaling, increase the P-tension (cage tension) on the
rear derailleur.
The bearing grease is intentionally overpacked and excess grease may seep at
the bearing seals during the break-in period."
Seems to be based on trail time. So that gives you another excuse to go out and ride.
My set is about two rides old. (ISO + M819Disc) and I've checked adjustment several times. So far they're great. No noticable drag.

Mine took longer than the suggested 60 hours... however, note that you won't damage them during the breakin period by racing on them, just check the bearing preload a couple of days before a race adjust if necessary and then you will be good to go. The best bit is 2 years later my Kings have been in 30 races and they just keep feeling smoother.
