OS Maps Routes Downloadable to GPS

I've recently downloaded an app for my iPhone which I will tell you a bit more about when I finish my run down of our most recent C2C but in the meantime I was chatting to a keen cyclist, a customer at work, and he introduced me to this map web site designed by The Hug. What this web site allows you to do is view OS maps in the UK and plot a route. It has the national cycle routes on it and will allow you to download or upload routes to/from your GPS. When downloaded it will point you in the right direction at junctions saving the usual stop and study map moments which can occur on a regular basis if you're not on a signposted route. Might be useful when we cycle Lands End to John O'Groats *cough*.
