Nolan's 14 is fourteen 14ers in the Sawatch Range in one foot-powered push of less than 60 hours. Route is open, but distance is 80+ miles and elevation gain is around 40,000' minimum. It's a big weekend and it's rarely done. Full description at mattmahoney.net/nolans14/
One controversy surrounding this challenge is whether the 60 hour cut-off refers to the last summit or the final trailhead. Also, if you go over 60 hours can you be considered a Nolan's 14 "finisher" (i.e., finisher of the "event"), or have you merely competed the Nolan's route?
Here's a (not complete) list of those who have finished the Nolan's route (thanks to Gavin McKenzie). For a more exhaustive list see Matt Mahoney's site. Times are given for the final summit and for the TH. Note that some are over the 60 hour cutoff time.
trailrunnermag.com has a nice article on the background of Nolan's.

#Note that Andrew started at the trailhead for Holy Cross at 7:45AM on 6/29 and reached the Fish Hatchery about 12 hours later. He slept a few hours and then started Nolan's at around 1:30AM on 6/30, and reached the Blank Gulch TH at 7:17AM on 7/2, thereby completing a traverse of the 15 Sawatch 14ers in about 71h32m (in addition to setting the FKT for southbound Nolan's)!
