Greg Rutherford dismisses critics and targets more records

Long jumper Greg Rutherford says criticism of his new British record has only motivated him to break it again.

The 27-year-old Olympic champion jumped 8.51m in San Diego last week, but rival Chris Tomlinson - who viewed it online - said it should not stand.

British Athletics will investigate  before ratifying Rutherford's jump.

"All I can do is turn up and compete," he told BBC Sport. "If other people have problems with my competitions then there's nothing I can do."

The jump, verified by USA Track and Field, took place at the Olympic Training Centre in California, which hosted the first of up to six meetings at which Rutherford will compete before the Commonwealth Games in Glasgow later this year.

"I'm never happy to settle," said the English athlete, who won Commonwealth silver at Delhi 2010.

"I want to jump further and hopefully do some special things because this year I've got a good opportunity with the Commonwealth Games."

Rutherford acknowledged he had to accept his results attracting close scrutiny since claiming gold at London 2012, and admitted he doubted whether he could return to the top of his sport after rupturing a hamstring and struggling at last year's World Championships.

"After the injury and how my body reacted at the Worlds, I wasn't sure whether or not I could get back to the level I had been previously," he said.

"I rode an Olympic high after London but then had to learn the hard way - I've now come through that and am ready for the challenges ahead."

Rutherford recently learnt he will become a father for the first time later this year, and believes it could benefit his career.

He said: "I think it'll help take the focus and pressure off competing a little, and hopefully the little one will be there with me."

In an interview to be shown on BBC One's Saturday Sportsday programme, Rutherford also reaffirms his desire to take up skeleton and potentially challenge for Winter Olympic honours in the future.

"It's something I'm really serious about giving a go after the Commonwealths," he told BBC Sport.

"It would be pretty special if I could win two Olympic gold medals, one at the Summer Games and one from the Winters, so I'm going to give it a real go."

Greg Rutherford will feature in BBC One's Saturday Sportsday programme on 3 May at 12:45 BST, along with Olympic road race champion Marianne Vos and England footballer Lianne Sanderson.
