No easy ride for Dasaolu
James Dasaolu has been warned he will have to run a new PB to continue his winning start to the season at the Sainsbury's Indoor Grand Prix.
The Londoner will face the toughest test so far of his gold medal credentials for next month's World Indoor Championships when he races at Birmingham's National Indoor Arena.
The 26-year-old, who is ranked second in the world over 60m, will come up against a loaded field, featuring Jamaican Nesta Carter and France's Jimmy Vicaut.
Also in the line-up is 37-year-old Kim Collins, who said: "It's a very strong field and I know people will have to go beyond their limits in order to win this weekend. I'm looking forward to that, because I need to win.
"It will definitely take in the 6.40 (seconds) region to win and there are guys here that are capable of that and it's a great track also."
Dasaolu has twice run 6.50secs this year - Cuba's Yunier Perez tops the rankings with 6.49s - while the Briton's best ever stands at 6.48.
That was set in winning silver behind Vicaut at the European Indoors last March.
Carter, who won 100m bronze at last summer's World Championships, is also eyeing a fast time at the venue where he set his 60m best of 6.49 in 2012.
He said: "This is where I got my personal best and I'm here again to hopefully run another personal best."
Also in the field are Vicaut's compatriot Christophe Lemaitre, American Mike Rodgers and Dwain Chambers, who will look to seal his place alongside Dasaolu on the British team for the World Indoors in Sopot.
The stadium record of 6.46 is likely to come under threat.
The women's 60m also features a British athlete in top form. Asha Philip ran 7.09 in Sheffield last weekend, a time bettered only by Murielle Ahoure this year, and the 23-year-old will be up against the Ivorian, as well as Jamaica's double Olympic 100m champion Shelly-Ann Fraser-Pryce, in Birmingham.
Philip's time was just 0.01 off the British record, suggesting Jeanette Kwakye's six-year-old mark could fall on Saturday.
Olympic long jump champion Greg Rutherford will make his first appearance of the season after a minor injury delayed his start to the campaign.
And he will not get the chance to ease himself into competition, up against the three medallists from last summer's World Championships, Russia's Aleksandr Menkov, Holland's Ignisious Gaisah and Mexico's Luis Rivera.
Holly Bleasdale will look to issue another statement of intent ahead of the World Indoors in the pole vault.
Bleasdale, second in the world rankings with 4.73m, is up against Olympic silver medallist Yarisley Silva from Cuba.
In the 60m hurdles, British trio William Sharman, Andy Pozzi and Andy Turner will be up against American pair David Oliver and Aries Merritt, the former the world champion and the latter the Olympic champion and world record holder over 110m hurdles.
Finally, Ethiopia's Genzebe Dibaba will bid for her third world record in 15 days in the two miles, having set new marks in the 1500m and 3,000m already this month.
The indoor two miles record stands at 9:06.26 and belongs to her compatriot Meseret Defar.
