Still dry but a heavy hoar frost: brilliant sunshine for a short time but after 8.30 a dull clouded sky. Very calm. Cycled in town + to Oakwood, back to Forest Road + then via Linglie to Peelburnfoot + Fairnilee altogether 22.25 miles1 + I felt much fitter though my legs were getting a little tired. Saw a few more [patients] after tea + got my hair cut.
1 If readers are curious about Dr Muir’s accurate mileages they may like to know that Dr Muir was in the habit of using what he called a ‘Velometer’ (see his diary entry for 30 June 1919) which was probably a mechanical device and evidently, from Dr Muir’s comments, designed to work on a specific wheel size therefore presumably counting rotations
