Cycling 2:51:00 [2] 29.3 km (5:50 / km) +270m 5:35 / km
On a steel bike with two working gears! From Lasswade, up the steep hill to Bonnyrigg, then along the Penicuik to Dalkeith cycle path, as far as Penicuik, then back along to Roslin Glen, where I turned off and into the glen, walked the bike up to the castle, and then cycled across the Bilston Glen Viaduct and back to Lasswade. Numerous short stops to write down various notes for OSM mapping, moving time was nearly an hour less.
