This looks really great! I'm going on a cycling tour next week so I can directly compare this to my google maps route.

At first glance your site shows the local "cycle highways" which is really cool. However I accidentally clicked on the map twice while scrolling around, and then couldn't figure out how to clear the route so I had to reload the page.

On closer inspection I noticed a button called "close route" which seemed to do what I wanted, but I'm not sure if it has other side effects
