In reply to drunken monkey:
There are assorted Strava-type routes on the FB page, but if you don't have any joy with that, I'll sort you a proper map.
But it's basically:
- steep out of Killin to start
- flat along to the burger van at the top of Glen Ogle and then down the old railway to what used to be the old Kingshouse Hotel, now Mhor 84
- along the road to Balquhidder and undulating back roads to Strathyre
- cross the A84 and go up onto forest tracks back to Mhor 84
- retrace your steps up the railway to the burger van
- down a slightly different route back to Killin, finishing along the main road and into McLaren Park.
It's a good day out - really friendly atmosphere along the way.
