Most office rivalries rise to a boil at conference tables and water coolers. At Google’s Boulder office, our grudge matches play out across topo lines. Last week, our third annual “Flagstaff Challenge” blasted off up Flagstaff Road, Boulder, Colorado’s signature hill-climb. Over 1,500 feet of elevation gain, the Flagstaff Challenge (mapped below) attempts to answer our office’s ultimate water cooler question – what’s really faster: two wheels or two feet?

Bloggers in the office fired up Google’s KML Embed Gadget to cook up an embedded Google Earth course map (if the map below is not in 3D, try installing the Google Earth plug-in, then start embedding KML’s on your own site!).
