Jessica Ennis shows sheffield steel

Ennis missed seven weeks of training earlier this year with an ankle tendon injury which forced her to skip the European Indoor Championships in Paris.

The 25-year-old admitted on Friday that she had become increasingly concerned with the injury, which "came on overnight" in training and has still not been fully diagnosed.

However, the Sheffield athlete belied those concerns in some style with victories in the 100-metre hurdles and high jump and a personal best over 200m.

That gave her a total of 4,097 points after the first day of the annual Hypo multi-events meeting in Austria, a lead of 300 points over Canada's Jessica Zelinka and 17 more than at the same stage of the European Championships last year.

Ennis went on to record a personal best of 6,823 in Barcelona, just eight points behind the British record set by Denise Lewis in Talence, France, in 2000.

She was disappointed with her performance in the 100m hurdles yesterday, despite winning in a time of 13.03s, but made amends by overcoming difficulties at 1.85m and 1.88m to win the high jump with a best of 1.91m.

"I'm very happy with that," Ennis said. "I was worrying I would go out at 1.85m so it was a big jump to do 1.91m. I jumped at Loughborough and that felt good but before that had only really jumped off my full approach once.

"I was really annoyed with myself in the hurdles. It was perfect conditions and everything was in my favour but I had a shocking start and was hitting hurdles.

"It was messy and didn't really come together. Hopefully I've made up for it with the high jump." The shot put is one of her weakest disciplines and she was forced to settle for a best of 13.94m.

But the final event of the first day, the 200m, brought a very satisfying new personal best of 23.11s as she finished second behind Holland's impressive Dafne Schippers, who also recorded a new personal best of 22.90.

Ennis has not lost a multi-event competition since missing out on the Beijing Olympics in 2008.

She won the world title in Berlin in 2009 and followed that with gold in the pentathlon at the World Indoors in Doha in 2010 and the European Championships in Barcelona the same year.
