While I don't know how this trail is officially classified, it is regularly used for more than just foot traffic.  It is regularly used by mountain bikers.  It also once was a horse path, although I'm pretty sure that the development in the area has all but eliminated that usage.  The path does NOT end at Noble Avenue!  It continues running eastward, parallel to the main (paved) bike trail (at varying distances from that trail), all the way to Coon Rapids Dam Regional Park.
