Here’s the part that mentions cycling, and you can read their full post from October 7 here, which outlines several other updates, changes and improvements to Google Maps:
The best part about this new dataset is that we’ve been able to add a lot of new, detailed information to Google Maps – information that helps people better explore and get around the real world. For example, college students will be pleased to see maps ofÃ‚Â many campuses; and cyclists will now find many moreÃ‚Â trails and paths to explore. Soon we even plan on providing you with biking directions to take advantage of this new data. Of course, in the true Google spirit of “launch and iterate,” we plan toÃ‚Â work with more data sources to add new features in the map.
