Jessica Ennis set for Glasgow Aviva international bow

World heptathlon champion Jessica Ennis will make her first international appearance of 2011 on Saturday.

The 25-year-old will go head-to-head in Glasgow with defending world indoor champion Lolo Jones of the United States in the women's 60m hurdles.

The Sheffield-based Ennis will also be action in the women's long jump.

European and Commonwealth 110m hurdle champion Andy Turner is up against American and world number one David Oliver in the men's 60m hurdles race.

Oliver, from Florida, was unbeaten outdoors last season and has run two of the six fastest times ever for the 110m.

However, Turner, 30, believes his muscular opponent could be fallible indoors at the Kelvin Hall.

"He's probably going to be going into the race full of confidence just based on what he did last year," said the Nottingham-born athlete.

"He was pretty much untouchable outdoors, head and shoulders above anybody else in the world.

"He doesn't know what it feels like to be beaten at the moment. He hasn't been beaten for ages.

"I ran 13.28 seconds to win [in Barcelona]. He probably only ran twice slower than that the whole year. That time isn't going to bother him.

"But he knows indoors that he's not the best in the world. He knows his start isn't as good as it probably could be or should be. He is a bit more vulnerable so I don't think he'll be taking it for granted.

"But it would definitely be a massive blow for him mentally if he got beaten, especially by me - I'm just a little skinny guy."

All eyes in Glasgow will be on Ennis' re-match with powerful American Jones in the 60m.

Ennis, who will captain Team GB, set a new British record of 7.97 seconds as she beat Jones in a surprise victory last January.

"I'm sure she will be looking for revenge. It will be good, I think it's good to have that competition," said Ennis, who is preparing for the European Championships in Paris this March.

"It was a nice surprise to win last year and I'm sure she will want to win this year.

"She might be a bit tired after her journey but I'm sure she'll be prepared and I'm looking forward to it.

"I feel in good shape and I feel ready to compete well so I'm hoping I can put down a good performance and keep it rolling into the rest of the indoor season."

As well as Ennis and Turner, Commonwealth 100m champion Mark Lewis-Francis, 2009 world 800m bronze medallist Jenny Meadows and 2008 world indoor silver medallist 60m Jeanette Kwakye are all in action, along with pole vaulter Kate Dennison.
