A fast, flat ride to the gates of Windsor Castle, where you can exchange light-hearted banter with the friendly armed guard about the merits of Zwift and Fulgaz.
The Royal Standard fluttering above the castle is proof that even Her Majesty has to stay at home during the Covid-19 lockdown.
After your brief visit to the castle, cross the River Thames to ride past Eton College and Dorney Lake (2012 Olympic Games) before climbing past Cliveden Manor (the Profumo Affair) to return to your starting point.
