DOUBLE Olympian Liz Yelling will tomorrow stake her claim to compete at a third Games when she lines up in the London Marathon.

The Parkstone-based runner is one of a number of Brits bidding to win the final women’s Team GB 2012 jersey in the gruelling event.

Yelling’s former training partner Paula Radcliffe, the world record-holder, and Mara Yamauchi have already been given the nod to take part in summer’s marathon.

But with one remaining spot up for grabs for the host nation, Yelling will strive to impress selectors when she races through the capital’s streets.

A veteran of the Athens and Beijing Games, Yelling will need to run a personal best and defeat British rivals including Claire Hallissey, Louise Damen and Susan Partridge in what is being billed as a Games trial.

In the process, all the home competitors are also understood to need to better the time set by compatriot Jo Pavey in London last year (2hr 28min 24sec).

Otherwise Pavey, who is not running tomorrow, is likely to remain in line for the third British women’s marathon berth.

Husband and coach Martin Yelling explained the task awaiting Liz.

He said: “It’s going to take a great run from any one of those girls to qualify. Anything less than a great run and they won’t qualify.

“Liz is actually in good shape for the first time since Beijing really.

“We had a little girl just after Beijing; that takes a bit of coming back from and also getting used to being a mum and a runner.

“But now I think Liz is ready to have a go and if it is good enough, then it is good enough.

“To qualify, she has got to run a personal best and be the first British girl across the line. That would put her up there in terms of the selectors’ minds.”

Yelling finished 25th in Athens before producing one of Beijing’s bravest performances to come 26th.

Having led the field through the opening miles of the 2008 race, Yelling was tripped from behind and trampled by a number of fellow competitors.

She regained her footing, worked her way back into the leading pack and finished the course, despite sustaining a rib injury which hampered her progress throughout the remainder of the race.
