Discovered a website and corresponding iPhone & Android apps that I've found to be very good.
Basically people the world over upload their GPS tracks to this website.
You register for free, log-on and search for a track in your area for whatever you choose to do whether it be walking, MTB, sight seeing, hiking, climbing, nordic walking, trail running etc.
With the mobile apps you can access the tracks with your phone and even make your own tracks to upload.
I've been using it for a few weeks now and find it great, I've uploaded a few I've done recently in Western Australia under 'Trail Running' (Ellis Brook Valley).
