With regard the thoroughly fascinating cul de sac of grandstands:
* When it comes to the use of motor-racing circuits, the Velon events I think are showing the limits of this.
* An historical perspective: back in dawn of time, most road races finished in vélodromes, from Bordeaux-Paris, through Paris-Roubaix, and on to the Tour de France. If the finish was scheduled for the afternoon, you could have other events on to amuse the punters and justify the ticket price. If the finish was happening in the morning, well you could sell your tickets for a lower price. Vélodrome finishes only ended in the 1970s, when the Tour left the Cipale and took to the Champs Élysées. Paris-Roubaix, of course, still finishes in a vélodrome: folk who've been in the stands for the race arrival can offer their take on how that works, from a fan's perspective. You also have some recent experiences from the Tour and the Giro.
* The Giro finished with laps of the Imola circuit in 2015 and 2018, didn't it? Anyone got any pics of the grandstands and how packed they were? The Tour used the vélodrome in Marseille in 2018, for a joint men + women's day: anyone there on the day can report on how it worked out? Spa was visited by the Tour in 2017 - anecdotes / pics, anyone?
* The general argument against circuit finishes – it's mean to fight to survive a 40-minute time cut in the mountains and get pulled for being lapped on a 3km circuit – is easily circumvented: you take the stage time at the entrance to the circuit. This is what has been happening in the sport pretty much since stage racing was invented. Today, every now and again some hack gets his knickers in a twist when it happens in the Giro d'Italia, forgetting that it also regularly happens at the Tour of California.
* Why are races seemingly using pavilions in preference to temporary grandstands? Could it be economics? Pavilions may pack fewer people than a grandstand, but pavilions can make more money from hospitality than a grandstand. In between laps, in a pavilion you're off getting a beer and a burger, whereas if you're in the stands you tend to stay in the stands, getting cold and bored.
* Temporary grandstands are used by the Tour, I think, on the Champs Élysées, but IIRC that's for VIP guests, as a kindness to their ageing knees.
