Aizawa Goes Sub-28, Suzuki Returns - Weekend Track Review

Elite road racing returned to Japan this weekend with Saturday's Hakone Ekiden qualifier and Sunday's National Corporate Women's Ekiden qualifier, but there was still a load of track action at every level.

Saturday in Miyazaki, one of the stars of this year's Hakone Ekiden, Akira Aizawa made his corporate debut for New Year Ekiden national champ team Asahi Kasei with a 27:55.78 win in the Miyazaki Time Trials 10000 m, his first time going sub-28. His former Toyo University teammate Kazuya Nishiyama was 2nd in 28:03.94, the best time by a Japanese collegiate student so far this year. Asahi Kasei had eleven men in the race under 29 minutes including Rio Olympics marathoner Satoru Sasaki, putting them in good position for another national title defense come Jan. 1. Kyoto's Ritsumeikan University had three men under 29, setting them up as a threat to the Kanto Region's monopoly on the podium at the Nov. 1 National University Men's Ekiden.

Defending corporate women's national champ Japan Post fielded most of its team at the Tokai University Time Trials meet in Kanagawa. Tokyo Olympics marathon team member Ayuko Suzuki returned from a long injury to win Saturday's 5000 m in heavy rain in 15:57.16 before doubling in Sunday's 3000 m with a 9:19.07 for 2nd behind teammate Hikari Onishi, winner in 9:18.43. Onishi was 2nd in the 5000 m in 15:57.96, with club runner Shiho Kaneshige (GRLab) the only other woman to break 16 at 15:59.52. Junior teammate Ririka Hironaka came back from her sub-15 5000 m last month to win Sunday's 1500 m in a PB of 4:16.48. Steepler Philemon Kiplagat (Aisan Kogyo) won Saturday's men's 5000 m A-heat in 13:33.92, with Alexander Mutiso (ND Software) taking Sunday's 10000 m A-heat in 28:06.21.

National High School Ekiden boys' course record holder Sera H.S. likewise tuned up for championship ekiden season at Sunday's East Hiroshima Nighter meet. The Sera girls took the top four spots and seven of the top ten in the 3000 m A-heat, Kenyan Theresa Muthoni winning in 9:18.25. In the men's 5000 m A-heat Sera had four boys under 14 minutes, Kenyan Cosmas Mwangi winning in 13:38.14, 2nd-years Shota Morishita and Shota Shiode 4th and 5th in 13:57.16 and 13:57.88, and 3rd-year Konosuke Shintani 8th in 13:59.32.

The Sera boys weren't the only high schoolers under 14 minutes over the weekend. At Saturday's Sayagatani Time Trials meet in Fukuoka, Jiyugaoka H.S. 3rd-year Ayumu Yamamoto ran 13:56.31 for 7th, beating Rio Olympics marathoner Hisanori Kitajima (Yasukawa Denki) among others. Kitajima's teammate Kiyoshi Koga returned from a 1:00:49 runner-up finish at this year's National Corporate Half Marathon to take the top spot in 13:39.70.

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd (updated)

3rd last year, Waseda University scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year Haruki Niizuma and Shunpei Yamaguchi put anchor Shinsaku Kudo out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University struggled a bit in the first half of the race but came on strong in the longer second half with 4th and 5th runners...
