OpenStreetMap
I created a website that shows elevation profiles for mountain bike routes based on nasa's srtm data. It works for routes that contain connecting segments only (check http://ra.osmsurround.org/ for route errors)
Go to http://osm.santolibre.net/ for an overview map or open http://osm.santolibre.net/routeinfo.aspx?relationid=1145205 for an example.

Very cool! I'd love to see this kind of elevation profile service for other types of routes, like bicycling and hiking. I tried to use a relation ID for this type of route, but it failed, so I'm guessing it only works with route=mtb. Would you consider expanding the service to work with other routes, or perhaps sharing the source code so others could setup similar services? Great work!

Excellent achievement. I too request you add bicycling and hiking.

Nice. cyclestreets has a little elevation profile feature (tucked away in the corner somewhere) which works for arbitrary routes, but I guess if you're going to cycle over a mountain then the elevation profile really matters!
I love the mouseover interactions with the profile chart<->map.

The route info works for other route types too (i.e. http://osm.santolibre.net/routeinfo.aspx?relationid=345917). Just edit the relation id in the url manually and click 'Force reload'. If the route is valid, you should see a similar output like for a mtb route. I probably add overview maps for other route types like hiking in the near future.
