LONDON (AP) — Jessica Ennis won the Olympic heptathlon gold medal on Saturday, the first for Britain on the track.

Ennis started with a record in the hurdles and finished it off almost 36 hours later with an 800-meter run that was more like two victory laps of the packed, 80,000-seat stadium.

Ennis went into the last of her seven events with a lead of 188 points over Austra Skujyte of Lithuania and extended her margin by winning the last race in 2 minutes, 8.65 seconds.

The capacity crowd went wild as Ennis collapsed over the line.
