This new piece of electronic mapping goodness has thrown a ton of fuel on the fire of my mountain bike geekery. I am getting way too much pleasure of riding around, building maps, and adding waypoints. Of course there is some tangible good that can come out of it: better trail review information for you, and a reduction in the likelihood that you'll get lost when using the data from Greg Rides Trails and Singletracks.com
One of the first rides I mapped was the Black Branch / Vietnam / Black Branch Connector combination. The trail had not been mapped on Singletracks yet, and since it was such a good ride I knew it had to be added!
Here are the elevation profile of the ride, an aerial view of the ride, and a link to the actual track file so you can download it to your own GPS:
