Crest Trail T25 (NM)
Clinton B. Portis posted the route:
I am planning an unsupported attempt on South (Monjeau Peak) to North (Nogal Peak) on the Crest Trail (T25) in the White Mountain Wilderness from (near) Ruidoso, New Mexico to (near) Nogal, New Mexico. The only speed time I could find is "Big Blister" on Every Trail. Their hike was listed as 10 hours.
Nolan's 14 (CO)
Nolan's 14 consists of climbing/hiking/running fourteen 14,000 foot mountains in Colorado's Sawatch Range in one foot-powered push of less than 60 hours. The exact route is open, but distance is about 90+ miles and elevation gain is around 44,000'. It's a big weekend, a prized goal, and only those who are fit and experienced in the mountains have succeeded. Full description at mattmahoney.net/nolans14/

Wasatch Ultimate Ridge Linkup (UT)
Jared Campbell's WURL page describes it like this: "The Wasatch Ultimate Ridge Linkup or “WURL” is an incredible ridge route circumnavigating Little Cottonwood Canyon in the Wasatch Mountains of Utah. The route mainly consists of scrambling, boulder hopping, and a few rugged trails. It is ~36 miles long with ~18kft of elevation gain." Campbell's site gives much more information and a list of completions.
