I've not seen as much as I usually would have, due to timings, but there have been some brilliant moments.
the 2 high jumpers sharing the medal.
a 13 year old winning a bronze for Britain today.
400m hurdles records in men's and women's both absolutely smashed (in the men's the top 3 were in the top 4 times of all time)
the Dutch 1500 runner falling on the last lap but still winning her heat.
classic Olympics stuff
