The 2022 Hakone Ekiden By the Numbers


The level at the Hakone Ekiden just keeps going up and up.  Every year it seems like it can't go any further, and then it does. 3 stages this year had new course records, 9 out of 10 legs had at least one all-time top 10 mark, and 4 stages had 4 times inside their best-ever 10. In the absolute sense, shoes have played a part in that over the last few years, but in a relative sense the best college teams have at least equalled the top of the corporate leagues, and the teams behind them are getting closer and closer to the same level.

At this year's 98th running on Jan. 2 and 3 Aoyama Gakuin University broke its own course record to make it 6 wins in 8 years. AGU clocked 10:43:42 for the complete 10-stage, 217.1 km course, an average of 2:57.9/km the entire way. How does that compare to Honda, which won the New Year Ekiden corporate men's championships on Jan. 1? Honda ran 4:51:04 for the 7-stage, 100.0 km course, averaging 2:54.6/km over an average 14.3 km stage length. Two of Hakone's stages have net elevation changes of 691 m, one going up and one going down. Taking those out and using AGU's best 7 of its remaining 8 performances, it did 154.1 km in 7:29:04, an average of 2:54.8/km over an average 22.0 km stage length. You'd have to think that if its runners were handling shorter stages like the corporate teams they'd be able to find the extra 0.3 sec.

11 teams at Hakone broke 11 hours for the complete 217.1 km course, the most since this version of the route started being used in 2015. Kanagawa University was 12th in exactly 11:00:00, and 3 other teams were within 28 seconds of them. Apart from 2020, when 10 teams broke 11, there's never been more than 3. 2017 didn't have any. The last 4 teams at the New Year Ekiden this year ran slower than 11-hour pace, 3:02.4/km.

On the New Year Ekiden's longest stage, 22.4 km, just 4 weeks after finishing 2nd at the final Fukuoka International MarathonKyohei Hosoya of the Kurosaki Harima team ran a 1:03:43 course record, a pace that would give 1:00:01 for the half marathon vs. the Japanese NR of 1:00:00. Out of the field of 37 runners on the stage, which drops about 15 m and had a tailwind of 8.5 m/s, 9 ran equivalent to sub-1:01 for the half marathon, 18 sub-1:02, and 31 sub-1:03. 

Wind was a much smaller factor at Hakone, where its field of only 21 teams produced the sub-1:03 equivalent performances and stage-winning times below. As you can see, the 21.3 km First Stage alone almost equalled the New Year Ekiden's longest stage, with 6 sub-1:01 equivalents and 17 sub-1:02, but with less than 2/3 the field size, 1/3 the drop, and 1/5 the tailwind. You can also see how good the performances on the Second Stage were when you take into account the extra distance and substantial net climb, and how the generational talents still shine through the higher overall level. 

First Stage CR breaker Yamato Yoshii (Chuo Univ.) is the U20 NR holder for 5000 m, and Second Stage winner Ren Tazawa (Komazawa Univ.) was the 2nd-fastest Japanese man ever on the stage. He's also the 2nd-fastest ever for 10000 m on the track. The only one faster on the stage Akira Aizawa (Toyo Univ.), is also the 10000 m NR holder. The two Kenyans faster than Tazawa in the Second Stage record books, Vincent Yegon (Tokyo Kokusai Univ.) and Mekubo Mogusu (Yamanashi Gakuin Univ.) are 0.98 and 3.12 seconds slower than him for 10000 m, Mogusu in the previous shoe era.

Excluding the mountain stages, out of 168 runners across 8 stages, this year's Hakone Ekiden produced a total of 13 sub-1:01 collegiate half marathon performances, 40 sub-1:02, and 65 sub-1:03, all but 4 by Japanese athletes. As we've shown before, the level at Hakone gives a good idea of how Japan's marathoners are going to look 4~6 years down the road. If you take the level at the New Year Ekiden as an indication of where things are for the marathoners right now, the future is looking very good indeed.

Fantastic article and analysis.
The first and second stage runs numbers were impressive. Especially the second considering the hills.
I think it shows there's potential for a sub 60 half marathon relatively soon by one of these guys and it makes it really interesting to watch their development.

Is there any half marathon or event anytime soon where most of these guys will be line up again against each other?

I hope to see some of them at the national ekiden on 23rd January to start with.

the times for the second stage are intriguing, 1:00:xx for 23.1km and 53m gain that is way below HM world record
Brett Larner said…
The times listed here are the equivalent half marathon times for each stage, not the actual results on those stages.

Also, some of the top people are supposed to run Marugame next month, but we'll see if it happens.

Measuring Marathon Courses by Bicycle

http://news.searchina.ne.jp/disp.cgi?y=2013&d=0110&f=column_0110_034.shtml translated by Brett Larner The full marathon is a sport where you compete over 42.195 km, but how do they go about measuring that distance?  Today we're going to look a little bit at how they go about certifying the distance of a marathon. The reality is that major international marathons use a bicycle to measure the distance.  This rule is an international standard, and the same method of measurement is used everywhere.  It was put into place in 1986.  In order to ensure that the same method is used everywhere, a bicycle that meets IAAF specifications must be used for measurement. In the case of Japan's major marathons, to be certain that the distance is correct a provisional measurement is first made.  Before the course is certified using a bicycle the course is measured using a 50 m-long length of wire to determine that it is in fact 42.195 km.  When a bicycle is u...

Ai Hosoda Announces Retirement

photo © 2025 Victah Sailer/Photo Run, all rights reserved On Jan. 8 the Edion women's corporate team announced that Ai Hosoda , 30, will retire at the end of March this year. The Tokyo Marathon will be her last race. At Nagano Higashi H.S. Hosoda ran in the National High School Ekiden her 2nd and 3rd years. During her 3rd year at Nittai University she won both the 5000 m and 10000 m at the Kanto Region University Track and Field Championships, going on to win the bronze medal in the 10000 m at the World University Games in her 4th year at Nittai. After graduating she joined the Daihatsu corporate team, debuting at the 2019 Nagoya Women's Marathon in 2:29:27. 2 years later she transferred to Edion. She qualified for the Paris Olympics marathon trials at the 2022 Nagoya Women's Marathon and finished 3rd in the trials in the fall of 2023, but was later bumped down to Olympic alternate after another athlete ran a faster time. Instead of the Olympics, Hosoda ran the 2024 Ber...

Nat'l University Ekiden Updates Here

Looks like I just went over my update limit on Twitter - sorry, it's the first time I've tried to use it for this. I'll look for another option next time. In the meantime I'll add updates to the comments below. Not sure if that has a max too but I guess we'll find out. Update: Part one of the Nationals commentary can be found here .
