I coded a Wordpress plugin, for selfhosted sites that pulls your route from canalplan and you can then blog about it - creates summary maps, a post for each day with a map and some stats in it, and also allows you to link back to places in Canalplan and canalplan will link back to your blog posts Once the route is imported to the blog you can adjust each day.

Just doesn't work with the WP modern editor as I wasn't going to learn a whole new programming language. Moved off wordpress to classic press which solved the problem
