Scottish Cross Country & Trails

Hi all, I'm really keen to try out some trail runs but don't have a clue where to find any good starters as I'm usually a road runner but really want to switch it up a bit. However, google can tell me nothing and I don't know anyone that is into trails.

I thought it would be ideal to start a thread for sharing any new routes (as hard as it is to share your hidden running gems)

I live on Loch Lomond side near Balloch.

Any help guys?

Much appreciated.
