Michael Moore has just posted the Journal from his 17 day solo LEJOG, undertaken in 2010 at the age of 65.  He was supported by his wife in the car and used the CTC YHA route as a basis.

What makes Michael's Journal different is the detailed and comprehensive day-by-day, turn-by-turn route guide - you could print the pages, jump on a bike and follow the route.  In addition there is also a .zip file containing a complete set of  .gpx files.  Go to The Journals, LEJOG and see No 565.
