Olympic champion Eliud Kipchoge fires warning to Athletics star Mo Farah

Olympic champion Eliud Kipchoge has fired a warning to Mohamed Farah ahead of this year’s London Marathon.

Kenyan athletics star Kipchoge won the event in 2015 and 2016, and the 33-year-old will compete again in 2018.

According to BBC Sport, Farah has run two London Marathons but April's race will be his first since switching focus from a track career in which he won four Olympic and six world titles over 5,000m and 10,000m.

“He's a tough and respectable athlete. I think he will be successful immediately,” Kipchoge told BBC Sport.

"I'll be taking Mo Farah very seriously. He's a very high profile person and I can say I'm respecting him and treating him with total seriousness. He'll be a big challenge."

Farah, 34, pulled out as planned at the halfway mark in the 2013 London Marathon and the British star finished eighth in two hours, eight minutes, 21 seconds, in 2014.

Kipchoge won a world title over 5,000m on the track in 2003.

He believes Farah's pedigree as a six-time world champion will lead to a smooth transition now that road events are a focus.

"It does take time to make that switch but I'm sure Mo will be successful. It won't take long. Mo Farah is serious. I believe if you plan and prepare well, winning and success can come."

Nathan Lyon: Australia can expose the ‘cracks under the surface’ in Ashes

Australian spinner Nathan Lyon believes his team can expose the “cracks under the surface” of England in the first Ashes Test, which begins later this week.

Australia and England will face off in the first Test starting at the Gabba on Thursday, with the Brisbane venue traditionally a nightmare venue for the tourists.

In the 2013-14 Ashes, Mitchell Johnson tore into England’s batting line-up to set the tone for a 5-0 whitewash in favour of the Aussies, and Lyon believes the survivors of that tour still have some hang-ups the hosts can exploit.

"There's some cracks underneath the surface with the fellas who've come out here," said Lyon, one of only three Australians remaining from that 2013-14 series.

"Alastair Cook, he faced Mitchell Johnson out here. Joe Root got dropped last time he was out here.

"So there are some cracks under the surface that we can hopefully ruffle the surface and crack them right open again and put them under pressure.

“Our job as the Australian cricket team out here is to put these guys under pressure and make them feel as uncomfortable as possible."

Johnson may no longer be active for the Australian team, but the way he intimidated the English - along with the support role played by the likes of Peter Siddle and Ryan Harris - has set a template the hosts would like to put into place for 2017-18.

"The impact that he had, that transcended the cricket field," fast bowler Pat Cummins said.

"It put fear in them, when they were sitting around waiting to bat, in between games they were thinking about him, how they were going to face him.

"The ones that stick out to me are the Gabba and seeing a couple of their bowlers - Stuey Broad and Anderson - from our point of view they looked like they didn't want to be out there.

“They didn't want to bat. They'd try and swerve away from the balls before he'd kind of even released them. Hopefully we can create that kind of anxiety in them."

Semenya not concerned with gender testing rubbish

South African Caster Semenya, dogged by gender accusations since shooting to fame in 2009, has played down efforts by track and field's governing body to change rules on naturally occurring testosterone in female athletes.

Semenya is back in the spotlight following a study funded by the IAAF and the World Anti-Doping Agency (WADA) that showed female athletes with naturally high levels of testosterone enjoy a competitive advantage of up to 4.5 percent over their rivals.

“Those are the things, the issues, that I don't focus on. It's not my business. It's their business,” says Semenya. "Those are the writings that I've being seeing since 2009.”
