Jeff List did the C2C2C in 11h14m on Nov. 25, 2008. His ascent time was 6h21m. He repeated the route on Nov. 25, 2009, in 10h33m, with an ascent time of 6h5m. List has some excellent info and links regarding the C2C, plus splits on his C2C2C runs in 2008 and 2009 here.
Trip Report: November 25, 2009:
I did my second full out-and-back Cactus to Clouds (C2C2C) in 10:33:16, again in self-supported style. (Note that it would be tough to do a completely unsupported C2C2C—I didn’t see one drop of naturally running water.) Again I carried 100 oz of water from the start, and had about 30 oz left when I reached the faucet at the Long Valley Ranger Station
I was chasing my splits from last year the whole day. Upon reaching the Long Valley Ranger Station after an 8000’+ climb, I was only one minute ahead of last year, which was a bit discouraging. However, I managed to get 41 minutes ahead of last year by the end.
The weather was perfect—nice and chilly the whole way up, but virtually no snow anywhere. It got a little warm near the bottom on the way back, but nothing serious.

Trip Report: November 25, 2008:
I did a full out-and-back Cactus to Clouds (C2C2C) in 11:14:20, in self-supported style (I carried all my food from the start, but got water from the ranger station, an unnatural source).
The weather was cool and cloudy, with some snow and sleet above 9000', but only a dusting on the ground. Overall, the conditions were ideal, with no desert heat down low or significant snow/ice up high. I started with about 100 oz. of water at the base, and had about 20 oz left when I reached the next available water at the Long Valley Ranger Station after 8000' vertical.
