TEST ROUTE (Duvall to SULTAN via gravel and Ben Howard Road) A short, SEATTLE AREA Garmin MapSource route so you can test your "systems. It's just an exercise to get some experience loading and "activating" a route on your GPS. This Garmin MapSource route starts at Big Rock Road (on Hwy 203 near Duvall), ends where Ben Howard comes out at Sultan using some decently rough gravel. Along the route is a spot on Youngs Creek that's a "notable geographic feature" and a neat place to swim on a hot day. If you've NEVER used your GPS to navigate a route, please give this a test. It's only 18 miles and is about 1/3 paved, you can ride it after work on a weekday. Click here to download the route. You will receive a zipped file called BigRock-Cedarpond.zip. It is a compressed forlder with two files of identical routs. One is a Garmin Mapsource "gdb" file. The other is a "GPS Exchange" file ".gpx", for use in GPSs OTHER than Garmin. Just FYI: MapSource update v6.11.5 (Sept 21, 2006) is available (free download). We highly advise that you create some "GPS routes" on your own so you know how to interpret the GPSs instructions. You still have to use your head, but the GPS allows a more complicated route with many obscure intersections, and allows riders to space out for dust. It starts easy, smooth. At the end of the 1st route, stop and look over the bridge. Just outside of Skykomish are side-jaunts to teach you to heed the GPS instructions.
