Let's run Davis Islands.

We'll meet at the Molly Malone’s Irish Pub and run down Channel drive on our way out to the Yacht club. You can turn at any point, do an out-and-back for about 5 miles, or do a complete loop around the island to get about 9.5 miles.

Here's the route http://www.gmap-pedometer.com/?r=7535219.
