The Olympics are always interesting. We get to see events and countries that we would not normally see. The men's 100m was incredibly close as they were all within a small fraction of a second. I suspect they change their pace at the end and that may make it look like they slow down, but they really have to run through the line.
There can be upsets. Neither of the favourites in the 1500m won it. Of course Simone Biles did not get as many golds as predicted in the gymnastics, but she seems to have a good attitude. It is amazing that some people have more golds than many countries will get in total.
I've enjoyed the rugby, kayaking, tennis, BMX and other sports. I just haven't been able to see everything. Team GB are doing pretty well and should get more medals.
We attended a few events at London 2012 and it was just great to be part of it.
