I have just finished plotting the route for the 100 on to Tracklogs. If anyone wishes to make use of my labours they should go to
GPX Files and save each file excluding the directory. Remember you will have to find a gpx file on your PC. What I have done has no official capacity and I understand similar information will be provided by the organisers in due course. It was quite a task and I had to refer to Google Earth several times so use it at your own risk but it should save you a lot of time.
