Jenn Shelton announced on instagram that she had bested this record by 18 minutes, with a time of 22h04m47s on August 30-31, 2015. This is the third fastest time by anyone, behind only Robbins' outstanding 2015 FKT and Skaggs' 2006 run. Shelton's complete report is as follows: "Here's (a photo) from Sunday, starting a 93 mile loop on the Wonderland Trail around Rainier. 22hr04min47seconds later I finished. Thanks to Krissy + Darcy for setting a fun goal, and of course thanks to my silly crew @haydenteachout (photog) and some opinionated little fucker named Colin."
Trail Runner Magazine has a nice article on Gary Robbins' and Shelton's runs.
