Ohuruogu ready for sister act

Christine Ohuruogu is convinced younger sister Vicky could prevent her winning a third consecutive Olympic medal in Rio de Janeiro in 2016.

After a year that saw Ohuruogu add a second world gold to her increasingly illustrious collection, it might be stretching the point to suggest the 29-year-old Londoner is looking over her shoulder just yet.

But Ohuruogu believes younger sister Vicky - who is nine years her junior - is beginning to show signs of emerging from her considerable shadow and making a world-class name of her own.

The younger Ohuruogu was part of Great Britain's bronze medal-winning relay squad in

Moscow alongside her sister, in a year which saw her lower her 400m personal best to 53.09 seconds in Cork.

Christine Ohuruogu said she "feels bad" that her own success makes it harder for her sister - but has challenged her to shatter the assumption she will always be left trailing in the former Olympic champion's wake.

Ohuruogu said: "I want her to beat me. Don't just think that because I'm the older one I have to be in front all the time. You try to beat me because that will make me work as well.

"I hope that by encouraging her to set her standards high, she can see my work ethic and is willing to follow that.

"I'm not just saying this because she's my sister, but I really do like the way she approached the 400m.

"I think it's always going to be hard for her being compared to me and having me in the group.

"When I told her I was staying on for Rio I think I heard a slight groan because she knows she's going to have to deal with me.

"I've told Vicky I'll teach her everything I know but ultimately the work stops with her. I can't run a race for her. That's what she's going to have to learn herself.

"I just want her to run and set her own goals and feel pleasure working towards them."

After a stellar year following the disappointment of missing out on a second straight Olympic gold in London, Ohuruogu is one of 10 athletes short-listed for this weekend's BBC Sports Personality of the Year Award.

And Ohuruogu insists she is as driven as ever as she gets back into top-level training for a relatively tranquil 2014, in which she may skip the World Indoors in Poland and concentrate instead on the Glasgow Commonwealth Games.

Ohuruogu added: "I'm back in training, it's my job and it's not really difficult at all. It's quite nice that I've never really hinged my career on just winning medals. I actually have a genuine passion for what I'm doing.

"As I stand here now, I think [Rio] is a worthwhile goal to put in and I think it is something I can realistically aim for, providing I'm injury-free and healthy enough to compete.

"I'm perfectly comfortable saying that."
