World XC silver medalist Bedan Karoki leads field that includes Abraham Cheroben (58:48), doper Matthew Kisorio and Leonard Komon.

Bernard Lagat, Wilson Kipsang and Haile Gebrselassie are the biggest names, but the winner will likely come from the quartet of Stephen Sambu, Stephen Mokoka, 10K road WR holder Leonard Komon or '11 10,000 world champ Ibrahim Jeilan. Defar, who missed 2014 due to pregnancy, will race for the first time in 20 months against a field that includes Betsy Saina and local favorites Gemma Steel and Jo Pavey.

Wilfred Murgor and Leonard Komon were a close 2-3 both clocking 59:57. Worknesh Degefa won the women's race in 67:14 as pre-race favorite Lucy Kabuu was only 6th (70:25).

We break down Chicago 2014 for you some more and refuse to go negative about Kenenisa Bekele. We also try to highlight some action that was overshadowed by Chicago last week - including a great run by Emily Sisson and wins by Quenton Cassidy and Josh McDougal. Then we wonder if we should get on steroids, complain about the price of road races (in Kenya) and tell you how Japanese running is being overrun by Kenyans and Ethiopians.

The top PR in the field is Kenyan Jonathan Maiyo with 2:04:56.

In March, he had the fastest 13.1 debut in history at 59:14 and is looking to go out in 62:30 for the first half.

Rupp will face a deep field, including Leonard Komon, Sam Chelanga, World bronze medalist Paul Tanui and Olympic 5th placer Bedan Karoki as Rupp attempts to become only the 4th man under 26:48.00 in the last 7 years.

Sambu ran 27:39 as Komon ran 28:17 getting his first loss over 10K on the road since February of 2011. Sambu also just missed the 8K WR along the way. Joyce Chepkirui won the women's race in 31:17.

1:06:19 Half-Marathoner Joyce Chepkirui leads women's field over Former World XC champion Gelete Burka and Delilah DiCrescenzo.

Komon was pretty spectacular and wanted even more - the World Record - as he went out with the wind in 13:39 (57:36 pace). LetsRun.com wind genius John Kellogg estimates the wind might have cost Komon around 17 seconds. *Results *Ken Nakamura: List Of Fastest Half Marathon Debuts In History *Chronological List Of All Sub-60 Half Marathons In History
