I'm doing a british heart foundation ride next sunday round the isle of wight(about 70 miles).
I have a garmin edge 605 and am planning to use this on the ride, when I start from ryde and go on the clockwise route..

Anyone know where i can download a compatible route which will allow me to get round?
I rode this last year, and while there are signposts showing the route, there not as frequent as they could be if you don't know the area, and it's small country lanes you are going down.

I also don't know what type of route I need to download, should it be a gpx or tcx file?
