Special 21 mile Bank Holiday ride to Alexandra Palace and back, using a different route each way.  Begin northwards through the City and Islington. At Canonbury make the first of several contacts with the New River. Continue to Clissold Park (2^nd New River sighting), then Woodberry Wetlands (New River 3) and Finsbury Park (New River 4).  Roughly following the New River has ensured a flat ride to this point.  But that changes as the route travels north.  From Finsbury Park pick up Quietway 10, crossing the New River another 2 times. At Alexandra Palace Station, leave Q10 and ascend to the Palace and collect the reward for climbing, a view down upon London (and lunch at the Boating Lake Café).

Return route runs a bit to the west of the outward route.  Initially along a short part of the Parkland Walk to Muswell Hill then round to Archway Rd close to Highgate Station in order to join the longer section of Parkland Walk, a green path along disused railway to Finsbury Park (info at https://underground-history.co.uk/northernh.php).  Delightful, nearly 2 miles of off-road path.  Through the SW corner of Finsbury Park then join Q10 going south past the Emirates Stadium, through Barnsbury and Legal London to join the East-West Superhighway (CS3) at Temple Avenue.  CS3 to Monument and across London Bridge to finish.  Hope to finish around 3pm as we will be going at our usual rather easy pace with plenty of stops at places of interest.  Everyone welcome on any type of bike.
