The Australian women's 4 x 100m freestyle relay team won gold yesterday in the pool with a new world record of 3:29.69. They were 3 seconds ahead of second place with the rest of the field (positions 2-8) separated by only 3 seconds. In short they smashed everyone else.
If a doping nation (eg China, Russia etc) had been in first place in this race, would people be questioning the performance? The result doesn't look normal to me. I can't understand in a mature, highly competitive sport, how one team at the elite level can be so far ahead of everyone else.
To be fair the Australians were the defending champions (they won in London as well) and world/Olympic record holders prior to the final, so it wasn't a surprise. I had expected the Americans to be closer to them though (they were nearly a second slower than in Rio). Emma McKeon's 51.35 was the only really crazy leg in that final.
