Went out and did the Crestone group (Humboldt, Kit Carson, Challenger, Crestone Peak, Crestone Needle) in a day on Saturday 8/4/12. My round trip time from the upper South Colony parking lot was 9:17:05 with a 7:41:00 split starting/finishing at the Lower South Colony Lake. Trip report posted here...
As per Bill Wright's site this beats the old FKT of 9h45min from a campsite at South Colony Lake and sets a new number for the new South Colony TH (9900ft).
My SPOT hasn't been sending out signals very well, so only recorded a few points from the day
