Shall we have a try for this coming Sunday, June 1, 10am. We could meet at the Loch Leven Lodges car park, there's loads of parking space there. http://www.lochlevenlodges.co.uk/coffee%20shop.html.
The best way out (to include the singlespeeders) is to ride the road out to just west of Leslie to pick up the singletrack road up to the reservoirs, turn up the farm road to the Golf Ball, then ride along the ridge to Glenvale, it's an easy spin back from there for a mellow 3 hr ride for those short on time.
We could add the second Pillars, Maspie Den, Golf Ball Scotlandwell descent loop for another day when folks have more of an idea of what to expect.
