The leaders for the full marathon passed around 8:20.
Here's another landmark:
At 11:00 I went for a bike ride. The walkers were bringing up the rear by then and there didn't look like any end in sight. The policewoman on North Tonti Street said they were expecting another few hours. When I got back at noon, the street was opened again and the race was done. There's certainly a lot of room on Esplanade Avenue when there aren't any cars parked on it.
