The Parade, Measured

A normal Sunday, all day — not just at kick-off. Crowds built from 9am, hours before the parade even started at 2pm.

Arsenal's title was confirmed elsewhere on the pitch, but the reaction was local and immediate. Within minutes of the final whistle, the streets around the stadium filled. Late-evening activity ran at 4–5× a normal Tuesday, and by 11pm one location alone was running at 7.5×. Five days later, the trophy lift on Sunday 24 May brought a calmer but still elevated 3–4× normal — the crowd already anticipating what was coming the following weekend.

The lift decays cleanly with distance from the route. A quick-service restaurant twelve metres from the route measured 5.0×; 60 metres away, 6.1×. A cinema 700 metres out saw +55%, and a location 1.6km away still felt +49%. A control location 2.2km from the route logged just +4% — a perfectly normal Sunday. One counter-signal makes the case even clearer: a leisure-centre gym ran 35–40% below normal. Everyone was on the pavement, not on the treadmill.

The crowd was building by 9am — hours before the 2pm start — and closest locations to the route ran at 5–6× a normal Sunday all day. Activity peaked as the parade itself passed through, at 6.7× around 4pm. But the highest multiple of the entire day wasn't during the parade at all — it was 8.6× at 11pm, as London kept celebrating long after the last float had gone. For anyone planning around a scheduled event, that's the real lesson: the crowd doesn't clock off when the parade does.
