The Bottom Bracket test...

The top video is standard bottom bracket, the bottom video is Enduro Ceramic bottom Bracket.

This is no clinical trial by any means, but it does highlight the minimal friction ceramic bearing offer riders. I did some very quick sums, at a cadence of 80 RPM x 60 mins = 4800 RPM per hour x 12hrs (assuming you are pedaling half the time during a 24 hour event)= 57,600 pedal strokes on each leg. Over this duration any reduction in resistance will help a lot.

I have chosen not to change the bearings in my Mavic Crossmax SLR's purely because we all know Mavic wheels roll better than anything else on the market.
