This is a 5 mile circular walk from Liverpool Street station going through Shoreditch, Hoxton, Haggerston and Spitalfields via Columbia Road Flower Market, Hoxton Street Market and Hackney City Farm.
The Bishopsgate exit of Liverpool street station looks like:
I will wait at street level next to the Starbucks booth at 2pm. That's where the two grey pillars are in the photo above.
Break point and latecomers pickup point is around 2.45pm-3.15pm at Geffrye Museum (near Hoxton overground station). We'll stop for half an hour and meet back at the Geffrye statue to continue our walk. See picture below:
I am aiming to finish the walk by around 5pm at a pub near Liverpool Street Station.
