I'm not sure why it took Runner's World so long with this, given that MapMyRun has been around for at least a couple of years.

Nonetheless, runners should welcome the Runner's World Route Finder, an online resource powered by TrainingPeaks. The RW Route Finder enables runners around the world to both search for or map new running routes in their own community or wherever they travel.

More details from Runners' World:

The RW Route Finder automatically searches for routes in the runner's current location and displays all the available routes on a map view, not just in a list. In addition to a map, runners can view interactive elevation profiles of any hills, providing a more complete understanding of the route's difficulty level. Finally, runners can search for routes in any part of the world simply by entering a new city in the search field.

In addition to finding new routes, runners may upload their favorite running course to the public RW Route Finder database. Runners also have the ability to drag and drop routes into their training log calendars, which automatically uploading the runs' distances and elevation gains directly into their personal trainer account. Routes recorded in the RW Route Finder can be instantly shared with friends on Facebook and Twitter, allowing runners to post their achievements in real time and receive feedback from the running community.

It's easy to test out the Route Finder, which I did. While it has a great interface and returns results quickly, there still appear to be some bugs in the coding. A search for runs in "Saratoga Springs, NY" produced some excellent runs in that area -- along with a few courses in Saratoga Springs, Utah. Well, they'll come in handy if I'm ever passing through.
