Prior to Briana Tidd, Cath Goodwin had the women's best time of 4d19h56m, set Aug. 27 - Sept. 1, 2010. Her detailed report is here, where Tim Seaver also reports: Starting on August 27 at 5:14 am at the base of Carrigain, and finishing at 1:12am on Sept 1st at the base of Moosilauke, Cath Goodwin has completed the NH 48 in 4 days, 19 hours, and 56 minutes. She was supported by Tim and Val Charboneau, and harassed by me on a few hikes. Synopsis: It was hot. It was cold. It was beautiful. It was even windy at times. Occasionally, people got tired. Alright...that's my version and I am sticking with it.
4d 19h 56m
