Nice job! Here are some suggestions: Though it might break the simplicity of the app, it'd be nice if it could plot a road-based route between two points. It'd save a lot of clicks. :) Also, make the markers smaller and try to detect whether there are any existing plotted routes nearby. My route has a lot of overlaps and it can be hard to differentiate them. Another option is that if you click on an existing marker it will merge the route into it. To diverge from it, you could click the marker you want to diverge from. Make markers draggable and update distance and height metrics while I drag them. That would be a good way to check for better variations of an existing route. Show regular distance intervals. So that you'd be able to see the literal milestones of your route.
