5 Olympic things to know for Friday

Here are five things to look out for at the London Olympics on


1. 4×100 RELAY: The American women look like the team to beat in

the final.

2. OSCAR PISTORIUS: South Africa’s double-amputee runner

finishes his landmark first Olympics in the men’s 4×400-meter relay


3. BEYOND BOLT: Jamaica’s men run in the 4×100 relay heat, but

Usain Bolt is unlikely to feature. How much strength in depth do

they have?

4. DOPING: Just days before the eight-year deadline expires, the

IOC formally stripped American cyclist Tyler Hamilton of his 2004

gold for doping.

5. THEY RULE THE WAVES: Australia bounced back – slightly – from

a disappointing Olympics, winning a sailing gold – its third – to

become the most successful nation on the ocean at these games.
