Comparing the Incomparable: The Wisconsin adidas Invitational Cross-Country Meet and the Hakone Ekiden Yosenkai 20 km Road Race

The world's two leading university men's distance running systems each held some of their fall seasons' major events this weekend.  In the U.S.A.'s NCAA, 36 university teams lined up at the Wisconsin adidas Invitational 8 km cross-country meet, with other top teams competing at the Pre-Nats meet later in the weekend.  In Japan's KGRR, the 11th through 58th ranked university teams in the Kanto Region were at the Hakone Ekiden Yosenkai 20 km road race, with the top 10 teams in the region scattered elsewhere on the track and road.



It's not really fair to compare cross-country to road racing and even less so to compare 8 km to 20 km, but how do the results from Wisconsin and the Yosenkai look in relation to each other despite the inequalities?  Click to enlarge the tables below to find out.


In NCAA cross-country, teams run 7 men with the top 5 placers scoring. Team scores are based on placing instead of time, creating some irregularities where teams with a faster average finishing time can place lower than slower teams.  Winner Syracuse's 5 scorers averaged 3:00.6/km for the 8 km course, with 7th-place UCLA averaging 3:02.3/km and 10th-place Florida State averaging 3:02.9/km.

Teams at the Yosenkai run from 10 to 12 men with their top 10 scoring.  Team scores are determined by total time of all 10 men, meaning the finish order mirrors how fast they actually ran.  Winner Kanagawa's top 10 averaged 3:02.2/km for the 20 km course, 5th-place Chuo Gakuin averaging 3:02.8/km and 10th-place Soka averaging 3:04.2/km.

In other words, although NCAA teams were at a relative disadvantage in running on a cross-country course, the average pace of Kanagawa's top 10 men over 20 km was faster than UCLA's top 5 men over 8 km, while the top 5 schools at the Yosenkai all averaged faster than 10th-place Florida State with teams twice as big running 2.5 times as far.  Reducing the variables by one and looking at just the top 5 scorers on the Yosenkai teams and reordering both races' results by average pace produces a better, if still not perfect, comparison.


Yamanashi Gakuin's 5 fastest men averaged nearly a second per km faster than Wisconsin Invitational winner Syracuse's 5 scorers.  The second-fastest Yosenkai team, Koku Gakuin, was also faster than Wisconsin Invitational runner-up Iona, and likewise all the way down the top 10 each of the KGRR teams' top 5 scorers averaged faster over 20 km on the roads than the equivalent NCAA team's 5 scorers did over 8 km cross-country.


At the individual level, 124 men in the Wisconsin Invitational averaged 3:05/km or better for the 8 km cross-country course, while at the Yosenkai 138 men did the same for 20 km on the roads. The top 3 finishers in Wisconsin averaged 2:57/km, 2:58/km and 2:58/km for 8 km, while the top 3 at the Yosenkai averaged 2:55/km, 2:55/km and 2:57/km for 20 km.  While only the top 3 in Wisconsin ran under 2:59/km, all of the top 10 at the Yosenkai were 2:58/km or better.  40 Wisconsin finishers ran 3:01/km or better to only 37 at the Yosenkai, but by 3:02/km Yosenkai numbers were again greater.  While more schools did run the Yosenkai the lower end of the field there performed at a lower level than the bottom schools in Wisconsin, and the number of teams represented in the totals above was similar.

The main objection here is bound to be that cross-country is far tougher than road racing.  The Wisconsin 8 km course features at least 10 sharp turns and a series of hills with a maximum elevation difference of roughly 30 m and a net climb of around 5 m, all run on soft surfaces.  The Yosenkai 20 km road course does feature a large proportion of flat and straight sections but also includes at least 19 sharp turns and 2 more 180-degree turns, with small hills over the final 5 km and a net climb of around 10 m.  The Wisconsin course was no doubt harder, but the key question is whether the difficulty of the course was enough of an issue to offset the fact that Yosenkai competitors had to run 2.5x farther than their U.S. counterparts.

This doesn't seem likely as a sole explanation for the consistent pattern of slower performances at Wisconsin seen in the second table above, especially considering the unseasonably hot and sunny conditions at this year's Yosenkai.  To put it differently, if the Yosenkai teams were to run 8 km cross-country in a week or two, could they perform similarly to how they did over 20 km on the roads?  That seems reasonable.  If the Wisconsin Invitational teams ran 20 km on the roads in a week or two, could they replicate their performances over the much longer distance?  That seems much less achievable.  Taken together with the fastest-ever winning time by a Japanese man at this year's Yosenkai and its world record-setting depth both this year and last, overall the results seem to point to increasing success in long-distance development in the KGRR relative to the NCAA where, as Race Results Weekly's David Monti documented last year, considerable success has come in middle distances.

The question of whether what's happening in the KGRR is too much too young is a good one that will see its definitive answer 6 years from now in Tokyo.  In the meantime, the question could be better put this way: if you are a high schooler looking at colleges and dreaming of being internationally competitive as a miler, which system is more likely to get you there?  If your dream is to be internationally competitive as a marathoner which system will give you a better chance?

Very interesting article. As with your past analysis of US/Japan it should get some notice over at the other sites. Perhaps an econometric/statistical model can be developed that holds constant different sets of variables and attempts to measure the different university systems along with race distances and results.

Very thorough analysis, thanks.

I read your Yosenkai coverage and watched some of the videos with wonderful memories, thank you!

this post is also quite interesting!
another objection might be that the average of top-5 taken from 12 samples can't be compared to the average of top-5 taken from 7 samples?

Nice to hear from you, Christian. In a more rigorous comparison that would be true, of course. Since coaches in the KGRR need larger teams than in the NCAA it goes without saying that they have bigger rosters to work with and that you'd expect sound coaching methods to produce a larger number of people performing at a higher level. A better comparison would be looking at the proportion of the total rosters from teams in each system reaching that kind of level, but that was beyond the scale of this post.

On the other hand, the difference in rank order between the 5-man and 10-man numbers for the KGRR results does show that in many cases the quality drops off somewhat after the top 5, so although it's not perfect there is still a rough comparison to be made. I hope to do a more accurate one later. Collaborators welcome.
This is by far the best and most enjoyable apples and pears comparison I have read in a long time. Thanks!

The Wisconsin race this year was held in windy conditions and, as a result, was relatively slow until almost 5km. It would be more appropriate to use the marks from other years when the competitors ran hard from the start. Also, the course was softer and the grass deeper this year. On the other hand, the course is probably 15 seconds short of 8km, or about 2 sec/km (unless they added a bit by moving the curve out at either (or both) of the bottom of the course or the curve before the 4km mark (first loop) and final straight (second loop). Someone not from Wisconsin commented on this; I have no idea if they are right.

Brett really good article. I think Japanese system way ahead as running 20k as compared to 8k. I know xc but even so. Well done. Keep up the good work. John.

Great article comparing two very unique systems. Any chance you could ever get some sort of access to any of these Ekiden teams and maybe produce a "how they train" series? Just a suggestion, keep up the good work!

As always, a thought provoking analysis.
One huge difference I experienced as a runner in Japanese middle school was the level of commitment that was demanded of us when we signed up for the sport. Quitting or doing a half ass job was considered embarrassing. If you weren't motivated, too bad, you had to work through it. That was part of the training.
I think in terms of a team sport, the Ekiden brings out the cohesiveness of a team sport better than XC. I know it's not strictly speaking part of the "system," but I'm sure the culture of accountability, responsibility, and maybe even "sense of duty" that emerges out of the interaction between Japanese culture and characteristics of the Ekiden have something to do with the depth of Japanese runners.
It would be interesting to extend the comparison to the HS level as a means to examine whether there is a case for too much too soon.

Kiplagat, Ichiyama, Tadese and Shitara Lead Marugame Half Elite Field

The Kagawa Marugame International Half Marathon is always one of Japan's deepest races of the year on the men's side, its 2012 running setting a world record for the most men under 64 minutes in a single half marathon in history. On the women's side the field is always smaller but still home to the 1:07:26 Japanese national record set by Kayoko Fukushi (Wacoal) back in 2006.

Edna Kiplagat (Kenya), Sara Hall (U.S.A.) and Betsy Saina (Kenya) lead the women's international field, two-time defending champ Eunice Kirwa (Bahrain) giving Marugame a miss this year. Fresh off a 1:09:14 PB at last month's Sanyo Ladies Half, Mao Ichiyama (Wacoal) leads a trio of Japanese women with recent sub-1:10 times, something that has become a puzzling rarity lately. Fukushi is also back, her recent best of 1:12:04 a long way from her best days.

Speaking of which, world record holder Zersenay Tadese (Eritrea) will be looking to break 60 minutes for the first time since 2015. His toughest…

Cheboitibin, Kiprono and Sonoda Top Beppu-Oita Mainichi Marathon Elite Entries

With just over two weeks to go the organizers of the Feb. 4 Beppu-Oita Mainichi Marathon have released their elite field for this year's race. With its history as an elite men-only race Beppu-Oita's women's field is still tiny given its status as an IAAF silver label race, but this year promises a good race between two local 2:32 women, 2016 winner Hiroko Yoshitomi (Memolead) and Yuka Takemoto (Canon AC Kyushu), that should see the 2:39:57 course record fall. Defending champ Haruka Yamaguchi (AC Kita) also returns with a 2:38:43 PB from last fall that puts her range of the course record as well.

The men's race is heavier-duty, with a spot in the MGC Race Tokyo Olympic Trials available to the top Japanese man under 2:11:00 and to up to five others if they clear 2:10. Hayato Sonoda (Kurosaki Harima) and Taiga Ito (Suzuki Hamamatsu AC) are the only Japanese men in the field to have run those kinds of times in the last couple of years, and with support from 2:09~2:10 men

Tokyo Marathon to Move to March Date Beginning in 2019

At a press conference in Tokyo on Dec. 12, the Tokyo Marathon Foundation announced that beginning in 2019, the Tokyo Marathon will move from its current date on the last Sunday of February to the first Sunday of March. The next Imperial succession is set to take place in 2019, meaning that February 23 will become the Emperor's Birthday national holiday starting in 2020. The race date is being preemptively moved to avoid any potential overlap.

According to the Foundation, setting up and breaking down the facilities necessary to hold the Tokyo Marathon takes several days. With the finish area being positioned in front of the Imperial Palace there were concerns that problems would arise due to the large number of people who would gather in the area to celebrate the Emperor's birthday.

Translator's note: The Tokyo Marathon previously experimented with a March race date in 2009 but abandoned it to return to February the next year. Since 1994 the first Sunday of March has been t…
