The route through Preston has been changed to avoid the shared use paths (combined pedestrian and cycle paths) as these will slow me down, although I expect I'll be using this kind of path to cross both the River Severn and the River Avon on day 3.
I've also amended the route between Hereford and Nailsea to take in the Wyre Valley. Originally I was avoiding the Wyre Valley and travelling down a bit further west but the roads were single track with grass growing in the middle and the risk of a 'get down' was a bit of a worry. Speaking to a friend who had just ridden to Bristol (on his way to Italy from Liverpool), he recommended the Wyre Valley route as a good way to go.
The only other thing I'm really working on is live tracking for the blog. During the Lands End to John O'Groats and Paris to Blackpool trips I used some software called 'Insta Mapper' which was then retired and then bought by another company with no further development. As technology has moved on the software hasn't been upgraded so this is no longer fit for purpose so I'm looking at other solutions so you can see where I am up to in real time (connectivity depending of course). At the moment it looks like I could be using technology for keeping children and the vulnerable elderly safe to track me.
Anyway here are the routes for the three days - anyone is welcome to join me for part of the route by the way.
