When Maeve and Homelander walk through the building under construction, though set in NYC, the building has the international green exit sign instead of the red US exit sign (which are slowly being phased out).
The arena for the race is named Hartsdale on the signs when it is first seen.
However it is actually Hamilton Ontario's Tim Horton Field. At 34:05, in a crowd shot that includes Mother's Milk, a Tim Hortons sign is visible in the background.
