I haven't been very successful with Veloroutes. They have cool features, but, at least for Vancouver, the elevation data is often inaccurate, leading to wildly exaggerated "climbs." It might not help that most of my rides are along the water and go over bridges. But even where it's unambiguously on land, the results are weird...

The undo feature doesn't work too well either. (Or is it me?)

But it's an otherwise cool site! I like the "stick to the road" feature (although it doesn't always work for my routes either). If they can fix the undo, I'll be using it more...
