The 10k open water swimming looked tough. GB got two silvers and a bronze. The Russian woman who won the ladies event stayed in the slipstream of the two leading Brits for the entire race, then came round them at the end to take gold. If she tried that in cycling, someone would shove her into the barriers. The GB bloke went off course and lost his first place. He had to settle for silver. The Dutch winner is a cancer survivor.

Sports that should be dropped from the Olympics?

Basically, any sport for which a medal is not the pinnacle of achievement. So: Tennis, Football and Baseball for starters.
