Was staying at the in-laws on friday night and determined to make a bike ride of it. Took the road bike with me, cycled from whitburn to loch lomond, then up the west side of the loch. Stashed bike then walked up ben vorlich and bivvied for the night part of the way back down. Got wet. Up at dawn this morning, came off the hill and retrieved bike, cycled to balloch and took the train home. Total distance c.90 miles on the bike and feeling pretty good for it. Although trying to use drops with a full pack on is a pain in the arse!
