Good to hear that you're back in the running again, Robert.
Re the Kilpatricks - one of my most memorable runs was from Old Kilpoatrick (got the train there), over the hills including Cochno Hill, across the moors to the Whangie, more moors to the West Highland Way, and ending up at Milngavie Station. Seemed like a long way at the time but I was young and fit then. I think there are more trails and paths over the Kilpatricks now - it was just all rough moorland then.
Go for a trot over the Campsies any time I can wrangle a work-related trip down to Glasgow :-)
