Usain Bolt faces stiff competition from fellow Jamaican Yohan Blake in the race to be crowned the fastest man on Earth.
A busy athletics schedule on Sunday in the Olympic Stadium sees Usain Bolt come up against fellow Jamaican Yohan Blake in the men's 100m final as well as Team GB's Christine Ohuruogu defend her 400m title from Beijing. Day Nine has the potential for much British success, leading with Ben Ainslie, who will attempt to become the greatest Olympic sailor in history with a fourth gold medal in finn sailing in Weymouth and Portland. While Paula Radcliffe has sadly dropped out of the women's marathon, Nicola Adams will represent GB at the ExCeL in boxing while Louis Smith is unleashed on the artistic gymnastics pommel horse at North Greenwich Arena four years after his Beijing bronze. World indoor triple jump champion Yamile Aldama is in action in the Olympic Stadium while there's the small matter of the men's tennis final at Wimbledon, which may or may not involve defeated Wimbledon finalist Andy Murray.
Gold medals up for grabs: 23
Today's medal sports: athletics, tennis, shooting, sailing, badminton, artistic gymnastics, weightlifting, track cycling, wrestling, diving, fencing
