Jessica Ennis is now the 1/6 favourite in the Olympics odds to win the heptathlon and matching her season’s bests in the final three events would almost certainly be enough to take gold.
Ennis had an up and down opening day, but her exploits on the track in London certainly outweighed the slight negatives in the field.
Personal bests arrived in both the 100m hurdles and the 200m, with her hurdles time of 12.54secs in the opening event enough to win gold in the individual event at the Beijing Olympics four years ago.
The result helped her secure an opening day total of 4158, which is marginally more than the sum she managed in Gotzis earlier this year when going on to set her current personal best.
If she can emulate her season’s bests in the long jump, javelin and 800m on day two, this will ensure a total of 6951 and nobody else in the field, including world champion Tatyana Chernova, has ever gone beyond 6900.
The long jump and javelin are technical events in which Ennis may underachieve, but her advantage suggests that some small hiccups can still be absorbed.
Chernova is 309 points behind Ennis at present, but is historically better than the Brit in all of the three events on day two.
There are opportunities for Chernova to reel in Ennis in both the long jump and javelin judging on her career bests, but she has not shown this form this season to date.
It is now 7/1 that Chernova wins the heptathlon and if she has any chance, she must go close to her 6.82m personal best in the long jump.
If she instead goes no further than her season’s best of 6.44m, this will cost her around 130 points and will rule her out of the gold, unless Ennis has a catastrophe of World Championship proportions in the javelin.
