I split this banner into 5 sections of 12 missions to do after work, starting and finishing at tube stations.
The middle section along the Euston road was a bit dreadful with traffic and bad drift and it wasn’t ideal hitting the British Library portals at 8.20pm (but they were at the end of a section so easy enough to pick up in the following session).
That said, there were some absolute gems of back streets around Farringdon and Marylebone. And the final stretch around Paddington wasn’t half as onerous as anticipated - only really complicated by rush hour around the station.
All in all, a very pretty banner, plenty of new portals, some good memories from walking it and would definitely recommend.
