2 guys I know (besides Biker395) did it this year. One friend, who has been off the bike a lot for many reasons, trained hard and finished the double pretty strong, for him, in 16 hours total time. I rode with him this past Saturday and was surprised at how much better he is riding than he has in a long time. He did mention the crashes on the STP including one in the first mile which ended one guy's ride, then another something like 30 miles in where a guy made a bonehead move and 2 went down with my friend lucky to not be involved. He found a competent cyclist to work with and the 2 of them traded pulls for many miles.

The other guy decided on the 2 day option. He had a group of friends and said they had a good time. They had tents at the half way mark.
