London to Oxford via Henley, with Helen G. Time was moving time - actual time was 8h15, including a 30 minute break at Pinewood and a 90 minute break at Henley.
Went out via NCR 6 (the Union Canal) and Knockolt, which was a pretty dull route out of London. Also a couple of sections of rough tracks (on NCR 61 and 4). Very fast from Henley - we got up to the high-point - Christmas Common - at a good pace, then flew down to Oxford, where I was rapidly running out of energy.
