Several Googlers (myself included) are headed to Moab, Utah to particiapte in the 24 Hours of Moab mountain bike race. Sponsored by Google Earth, we will be on hand to demo Google Earth and the neat features that pertain to GPS tracking.
Did you know that you can track your route (driving, hiking, biking, etc.) in Google Earth using a GPS device? This allows you to view your route in 3D terrain in the application and share this with others. To see what I mean, I've posted this file that describes the 24 Hours of Moab race course.
You need the Google Earth Pro or Plus to upload your own GPS files. To learn more about using GPS features of Google Earth, see this section of the user guide.
