With Ennis, athletics gets off to fast start

It won't take long for the British crowd to warm up when the London Games track and field competition opens on Friday at the Olympic stadium.

Five minutes into the program, Jessica Ennis and other heptathletes will line up for the 100m hurdles, the first of seven disciplines in the event.

Ennis, born in Sheffield and one of Britain's best chance for an athletics gold, will have to shoot out of the blocks fastest since the sprint hurdles is one of her best events in the two-day competition. She will hope to build an early lead over her rivals, world champion Tatyana Chernova of Russia and defending champion Natallia Dobrynska of Ukraine.
