It was pretty much a strong tailwind over the first 10 km and just a strong a headwind over the last 10, so it wasn't a surprise that the lead group of men went through 5 km in 13:59 and 10 km in 27:51. Up front in it were 59:30 collegiate record co-holders Richard Etir and Kotaro Shinohara, and sub-59:30 guy Emmanuel Maru. But with the National University Half Marathon having moved to Marugame last year there were a million fast Hakone kids up in it to, Hiromichi Nonaka from Koku Gakuin University leading the way but lots more right behind.
Etir and Maru opened up on the field after the turnaround, and by 15 km Etir was alone, 9 seconds ahead of Maru and on sub-59 pace running into the wind. Like everyone else he struggled to keep pace in the wind, sub-59 slipping away but easily taking the win in 59:07, a CR and new collegiate record by 23 seconds. Maru ended up almost a minute back in 2nd in 1:00:06. Uruguay's Santiago Catrofe won a sprint finish against Tomoya Ogikubo to set a new NR of 1:00:21 for 3rd, with Ogikubo tying all-time Japanese #8 in 1:00:22 for 4th and top Japanese.
4th and 5th placers Yuma Nishizawa and Neo Namiki both cleared 1:00:30, and Daisuke Sato of Chuo University made up a 10-second gap at 10 km to take the top Japanese collegiate spot at 7th overall in a PB of 1:00:40. The top 20 all broke 61, 11 of them collegiate runners, and excluding 2 people debuting, everyone in the top 25 except Maru and Norway's Sondre Moen ran a PB. A sub-61 half just isn't what it used to be.
It was a pretty strong contrast in the women's race, where despite having men around to run with only 3 people in the top 20 ran PBs. 2-time champ Dolphine Omare went out in an aggressive 15:26 and 30:47 through 5 km and 10 km, 1:04:57 pace, but slowed as soon as she went around the turnaround and into the wind. She ultimately missed her own CR from last year by 10 seconds but still took 1st in 1:06:15, her 3rd-straight Marugame title. "She was OK through 20 km, but she really had a hard time in the last km," Omare's coach Stephen Mayaka told JRN post-race. "In better weather she can do 65 for sure."
Saying pre-race that she hoped to run 65, Eilish McColgan went out in 15:34 and 31:18, 1:06:02 pace, but faded even harder than Omare over the next 5 km. But where Omare continued to slow McColgan rallied, faster than Omare by 1 second from 15 to 20 km and by 3 seconds over the last 1.0975. "It was hard," she told JRN. "I was on my own a lot of the time. Men kept coming back to me, which gave me something to target, but they had all gone out too fast and were dying so I kept passing them. There wasn't anyone I could latch onto."
Japan-based Susan Kamotho ran an extremely well-paced debut, only 16:17 through 5 km but then clocking 16:00-16:03-16:02 to move pass Australian Isobel Batt-Doyle for 3rd in 1:07:56. Batt-Doyle hung on to 4th in 1:08:51, telling JRN, "I wanted to run better since I'd run well here before, but it was a hard day out there and I just told myself to make sure I got under 1:09." Tokyo World Championships marathoner Kana Kobayashi took the top Japanese spot at 5th in 1:09:28.
