The Brazilian rider above says it was clear that the second group of around 70 horses, that was sent off at 6:30, was smaller than it should have been.
So how did they send only ~50 horses off in the first group at 6:05, when 124 were cleared to start? No one had a list of starters and scratches? Not one of the officials, volunteers, riders, crew members looked around and thought “weird, a bunch of people aren’t here yet, let’s all sit tight for five minutes and find out what’s going on”?
I understand it’s early in the morning, there was a lot of confusion in general, and everyone was nervous and excited and eager to get going. But horse sports are tight knit, I’m sure all these people at least know each other on sight. It just didn’t occur to anyone that the field was half as big as it should have been and entire teams weren’t present?
