Using Google Maps for my favourite running route

I've mucked around with Google Maps to set up my favourite running route. I then happened to find, in the latest Runners' World, some references to some website that do the job. I've now added my route to the USATF site. . FYI: there are other sites at www.favouriteruns.com and www.gmap-pedometer.com.

I now have some new marks.
8.5km: Shell bitumin tanks
12.5km: Small point 100m before short gravel crescent on right hand side of road
13.5km: Small gravel car port just past cable warning sign by building.
