Buzz Burrell & Peter Bakwin hit the CT back in 1999. They started the eastern end (Waterton Canyon) because it meant they could sleep at home in Boulder the night before the start, and because most backpackers go east to west. Bakwin got injured after 7 days and had to stop. Burrell went on to lower the record to 11d16h13m.
