I am a track/athletics fan. The Games have been great fun to see - but the hype versus what happens in actual events is disturbing.
Bolt was terrific - but I wonder what he could have done in the 200 if he didn't slow down at the end to goof around. (They kicked out badminton players for lack of serious effort.)
David Rudisha was truly amazing - and seems unnoticed for the only track world record set at the games. The man ran ahead, alone and fast for the full 800 - that was real effort that paid off.
It is worth seeing if you have not. This kind of thing is very rare and special.
