Here's the kit list that David Cotton used, Its not exactly lightweight, but he did have his girlfriend supporting him in a campervan, in which he slept most nights, so I expect most of the walks were done with a daypack.
He walked a distance of 6270.6miles (10,091km) and it took 3 or 4 days less than a year. A rather more reasonable average of 17.5miles a day, His daily route is described in detail, although unfortunately I can't get some of the links on his site working, the menu on the right gives access to his itinerary.
