A new app from those nice people at Adventure Cycling has 47,000 miles of mapped cycling, which I assume includes the Divide. Could be useful perhaps ... but I know nowt about apps, so it might not be.

you can see the data in a browser here:

Just had a look at it, you have to buy the routes and the Divide isn't available. It would be handy if you were riding one of the road routes and that's it.
