Check out www.bikely.com if you haven't already.

Here's a route I transferred to Bikely just to try it out. Once a
route is in there, you can print maps, cue sheets, edit the
annotations, etc. It also provides an elevation profile. It's done by
geo-mashing GoogleMaps, and also lets you switch the view to
GoogleEarth.

I can see it won't be long before GCBT routes will start appearing on
here. If we do put any on there, let's adopt the convention of
starting all route names with "GCBT" (my suggestion).

Cheers,
