I managed a 6h 01m century split (rolling time) on the TdC last year. About 6000' of climbing. I rolled across the finish line with 108 miles and another 30min on the clock.

Back in my tri-racer days I ripped out a 5h 10m total time at the Hancock Horizontal Hundred.

Now, I'm not in it so much for speed. Yeah, I'm looking to improve on this weekend's sub-14mph average, but I don't need to be busting my butt at 22mph the whole way.
