Thanks for all your help everybody.
The problem is that there is absoluetly nothing out there comparable to Tracklogs.
I paid £25 one-off for an OS map for the whole of N.Wales and could easily set up the routes on one map. Only problems are that I now cannot export them as one and Tracklogs does not operate as a company.
Garmin Basecamp seems full of problems. I cannot even find where to import the routes and the OS map tiles are a recurring cost.
I have come to the conclusion that there is no solution.
Bring back Tracklogs!!!!!!!!!!!!!!
