Ten Men Under 1:01, Five Women Under 1:10 at National Corporate Half Marathon Championships



Before last weekend only eight Japanese men had ever gone under 1:01 in the half marathon on record-legal courses, with another four on the old downhill Tokyo Half course. At last Sunday's Marugame Half four did it, two who had done it before and two who went under the national record in the first time clearing 1:01. At today's National Corporate Half Marathon Championships eight more did it, equalling all of Japanese history in the course of eight days and the previous record-legal history in a single race.

Not too much question why, but the racing was still good. Kenyan James Rungaru (Chuo Hatsujo) earned the win, 16 seconds ahead of the pack at 5 km in 14:33 and only going faster from there to his 1:00:27 finish. The main pack had a leisurely 14:49 opening 5 km before getting it in gear, dropping to 14:17 for the next 5 km and getting down as fast as 14:12 splits between 15 and 20 km. Kiyoshi Koga (Yasukawa Denki) was the first Japanese man across the line, dropping Kenyan Patrick Muendo Mwaka (Aisan Kogyo) and twelve other Japanese men to take 2nd overall in 1:00:49.

Hiroki Suzuki (YKK) was 3rd in 1:00:50, with the top ten all clearing 1:01 and the next four within 5 seconds of it. The twelve Japanese men in the top 14 all made the all-time Japanese top 25. Marugame last week set new records for number of finishers under 62 minutes, 63 minutes and 64 minutes. Today's race crushed all of them, with 46 men breaking 62, 71 under 63, and 86 clearing 64. What could March's National University Men's Half Marathon Championships possible bring?

The women's National Championships were divided in two, a 10 km division and a half marathon. The 10 km was mostly notable for its splits, with 26 of the 31 women in the race jogging a 17:35 first half and then blasting a 15:43 second half. Momoka Kawaguchi (Toyota Jidoshokki) won by a stride over Misaki Hayashida (Kyudenko) in 33:18, with Reina Hashino (Hitachi) 3rd in 33:26.

The women's half wasn't as crazily deep as the men's, but was still solid quality for a Japanese race. After a modest 16:46 opening 5 km a lead group of nine separated, going through 10 km skimming just under 1:10 pace in 33:09. The pack thinned to seven by 15 km before things really got moving, and with one km to go it was the proven Sakiho Tsutsui (Yamada Denki) side-by-side with Ayano Ikemitsu (Kagoshima Ginko) with unknown Kaena Takeyama (Daihatsu) right behind.

A teammate of Osaka International Women's Marathon winner Mizuki Matsuda, Takeyama had the gears to get the win, kicking away on the track with 200 m to go to break the tape in 1:09:12 to Tsutsui's 1:09:14, Ikemitsu close behind for 3rd in 1:09:16. All three of them made it into the all-time Japanese top 25. Juri Ichikawa (Yamada Denki) and Ikumi Fukura (Otsuka Seiyaku) also broke 1:10, with the next five under 1:11 and the top 20 all under 1:12. As the most neglected of the major long distances for Japanese women, the depth of the results were encouraging, whatever the boost from the footwear. Now they just need to incorporate the distance into the National Corporate Women's Ekiden to give them parity with the men and the same kind of leg up in marathon-directed development.

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...

Kipyegon Repeats, Toyo Wins Hakone Ekiden Qualifier in First Appearance in 21 Years

Back for the first time in 21 years after a disastrous 14th-place finish at the 102nd Hakone Ekiden this past January, Toyo University hit one out of western Tokyo's Showa Kinen Park with a solid win at the Hakone Ekiden Yosenkai, the half marathon that serves as the official qualifying race for the 103rd Hakone Ekiden. The top 10 teams in the Hakone auto-qualify for the following year, with the rest having to run the Yosenkai in October with a squad of 10 to 16 runners out of which the top 10 score on aggregate time, with the 10 fastest schools joining the Hakone field and top individuals from non-qualifying teams names to the Kanto Region Student Alliance select team to make up the complete Hakone field of 21. Driven in large part by an aggressive run from 3rd-year Yu Miyazaki , one of only 2 Japanese athletes to go with the big African contingent up front, Toyo won in 10:31:30, 1:03:09 or 2:59.6/km per athlete. As the first team to have broken the 3:00/km average pace barrie...

Ngetich and Mutiso Take Down Tokyo Legacy Half CR

In its 5th edition the Tokyo Legacy Half Marathon scored 2 new course records via Kenyans from the Ikaika agency, with 10 km WR holder Agnes Ngetich blasting 3 minutes off the old record to win by over 4 in 1:04:23, and Alexander Mutiso skimming just 1 second under the CR for the win by 5 seconds in 59:51. The 2 races played out completely differently, even if the paydays were the same for the winners. Surrounded by an envelope of male runners all the way to the final 100 m, Ngetich was out hard on the downhill in the first 5 km, hitting it on sub-64 pace in 15:08 before leveling out on the flat middle 10 km. Her next 2 splits projected to 1:04:09 and 1:04:17, and even with the uphill back to the stadium in the last 5 km she didn't fall far off from that, winning in 1:04:23. Runner-up Tabitha Njeri Kamau was nearly a mile back in 1:08:28, with Kamau's Mitsui Sumitomo Kaijo teammate Kazuna Kanetomo dropping a 1:10:17 PB for 3rd. Now an independent, track Olympian Kaede Ha...
