Commonwealth Games bronze medallist Zane Robertson makes his debut over 10,000m at the Prefontaine Classic Diamond League meeting in Eugene, Oregon, on Saturday.
Robertson's aim is to reach the 27min 45sec IAAF and Athletics New Zealand qualifying standard for the Beijing world championships in August. Also within his grasp will be Dick Quax's long-standing New Zealand 10,000m record of 27:41.95, set in 1977.
The Ethiopian based Kiwi is part of an intimidatingly strong field at the Pre Classic, headed by double Olympic gold medallist Mo Farah, unbeaten over 10,000m for almost four years.
Farah, 32, is the fastest British runner in history at every distance from 1500m (3:28.81) to the marathon (2:08:21).
Seven runners in the field have best times faster than 27 minutes.
