Here is the thing. For the virus to spread succesfuly you either need a close contact that lasts more than just a couple of seconds or a closed space where air is not flowing like outside. So the chances of a spectator standing (or running) by the course geting a cyclist infected are very very small (unless someone caughed directly into a riders face). I agree that they should close the start and finish areas for massive crowds. Small amount of people shouldn't be a problem. A lot of tourist destnations (beaches etc.) have been filling up for two months now and I don't see why 200 spectators of a race would be more likely to spread the virus than 2000 people on the beach... so as long as the keep the riders in their "bubbles" racing should go forward. Because it is inevitable that the amount of cases will go up. The decrease in May-June was due to the total lockdown in March-April. But I think a lot of countries realised that repeating that scenario would be utopical and far more harmful than the virus itself. So I think that even if the number of cases rises again (in a controled fashion ofcourse), they shouldn't just stop everything again. They have protocols in place and I believe that it is enough to keep the racing going.
