Can you imagine doing that course for 24 hours? I'd fall asleep sure as shit...

Four drivers (some with 5), 3.5 hour stints. No sleepies allowed. In the day, the teams had only 2 drivers, holly crap. ZZZZZZZZZZZZZZ
Any true enduro is mind numbing, the wear and tear on man and machine (including the men in the pit). I grew up appreciating the Daytona 24 Hr race, have rarely missed it. Le Mans 24 is by far my most appreciated race for the quality of the cars, the teams and the track. Never mind winning, just competing is awe inspiring. I find myself feeling for the teams that crap out early, having their hopes so high at the start, then not even finish. Then the agony of running nearly all the race, only to have something break with a few laps to go. Damn, that sucks. But, no matter what, I admire the effort these guys put out.
As for FM3 enduros, I'm glad they are around 1 hour or so. Other wise, we'd have to form teams in oder to stay awake.
