Google has enhanced its Maps API and MapsGoogle will now display EarthGoogle KML files. Here is an example. The KML file is appended to the maps dot google URL. Use a web service like Gmaps Pedometer to build trace routes. Use Gmap to GPX and create a GPX file. This file can be imported into Google Earth where the . KML can be edited. The paid Google Earth Plus version will shortcut the above steps as it has all of the features in one place.

I have run this loop many times. The Reedy River Park is very scenic and the residential areas quite nice as well. The route is paved. Some huffing and puffing on the steep parts.

After crossing the New Jersey Turnpike in the Secacus Medowlands find the Mill Creek Marsh. A back water bay habitat and a nice escape from urban blight. Soft trail.

The Upper Newport Bay is a tidal backwater preserve with bike and equestrian greenway. Starting from the OC airport in Irvine the cement and glass buildings give way to wildlife refuge past the UC Irvine North Campus. There is a fence to jump at the end of Campus Drive but it wasn’t much of a barrier. An access road joins the park. 6.2 miles

The pavement ends at the Aqua Caliente Indian Reservation and the trail portion becomes a hike due to desert terrain and steep rise. Otherwise, the route along North Palm Canyon, Tramway Rd., and the +1M residential area is paved. It’s a scenic 5.9 miles with a vista of windmill farms east of the Banning Pass.

One lap of the Fort Lauderdale Executive. The airport perimeter road is flat concrete sidewalk or pavement with soft grass edge. Many general aviation aircraft to view while maneuvering this 6 mile circuit.

Run-o-Meter
There are many sites that offer to maintain your running statistics. The Run-O-Meter site has the most Zen artistic layout to my eye.
