HI, Me and my brother in law took a couple off push bikes 2 yr running circa 1989/ 90,camping at Peel,stumbled on or got lost, is nearer the truth,and ended up finding interesting spots ,I guess we would have missed otherwise , the ,the Railway inn and the bridge at Union Mills,and the bit formerly known as Ballig bridge.I drank a helluva lot of okells that week and went home slimmer than before, with legs like tree trunks, the other poster is right about the old railway .I found cycling on the TT circuit that hour before roads closing terrifying,and would avoid that.
