Running the 2020 Tokyo Olympic Marathon Course

Tomorrow is two years to the day until the 2020 Tokyo Olympics women's marathon. On July 18 the IOC signed off on the Organizing Committee's proposal to start both the women's and men's marathons at 7:00 a.m. With Japan experiencing a record-breaking heatwave this summer this has caused a lot of concern in both the public and the media about the health and safety of the athletes, officials, volunteers and spectators during the marathons and other long outdoor events. As a 20-year+ resident of Tokyo and 14-year resident runner in the central area of the city I'd have to agree with the concerns, but since the IOC and other powers that be seem to think it'll be fine let's put my money where their mouth is.


Tomorrow I'll go out to run the Olympic marathon course at the actual time the women's race is scheduled to take place and report on the weather conditions throughout the run. A week later I'll do it again at the time the men's race will happen. I'd expect most of the women in the Olympic marathon to run more or less in the 2:30 to 3-hour range and the men in the 2:15 to 2:45 range. Needless to say I won't be running as fast as them, so to keep it within the same time frame tomorrow I'll run the first 20 km of the course, cut out the middle 8 km and go straight into the last 14 km. Next week I'll do the first 10 km then go from the 20 km to the finish, probably cutting out the turnaround leg between 31 and 35 km.

The forecast for tomorrow is for cloudless skies, around 60% humidity, almost no wind, and temperatures of 28˚C at the start climbing to around 33˚C by the time I plan to finish. Actual temperatures in the sun are likely to be quite a bit higher. NHK may be coming down to shoot some footage and talk to me about the experience, but either way I'll be live tweeting video and pics during the run so be sure to get in on the fun. If you do, feel free to buy me a sports drink and/or contribute to my hospital bills after the run via the link below. See you in the morning.

Hokkaido Marathon Elite Field

The Hokkaido Marathon happens Aug. 30 in Sapporo. Although it's not a top-tier race on the global schedule, the JAAF gives it special status in qualification for the MGC Race Los Angeles Olympics marathon trials, with 3 spots available to men who run under 2:12:00 and women under 2:32:00. Compare that to the criteria for making the trials by running the WA platinum label Sydney Marathon the same day, where men have to run under 2:06:30 and women 2:23:30 regardless of how they place. It's hard to see that as anything other than disincentivizing Japanese runners from racing abroad, with protecting the JAAF's financial interest in domestic races being the priority over getting the best athletes into the Olympic trials. But anyway, there are pretty good fields of people willing to not step out of line. All 6 women with marathon finishes to their name have run under 2:30 in the last 3 years led by veteran Hitomi Niiya with a 2:21:50 in Tokyo 2 years ago. Most are in the 2:26-2...

Olympic Marathoner Nakamoto Scores 10000 m PB

http://www.sponichi.co.jp/sports/news/2012/05/19/kiji/K20120519003286760.html translated by Brett Larner London Olympics men's marathon team member Kentaro Nakamoto  (Team Yasukawa Denki) set a 10000 m PB May 19 at Sayagatani Field in Kita-Kyushu, finishing 9th at the Kyushu Corporate Track & Field Championships in 28:54.59.  "A PB makes me feel pretty good inside about things," Nakamoto commented with a smile.  "I'll be going into marathon training in good shape." Nakamoto's previous best time was 29:04.24.  In today's race he stuck to the back of the lead pack, saving his energy for a intended surge over the final stage but unable to execute as planned.  "My closing speed is still a problem," he said without seeming too concerned.  His coach Naoki Yamagashira  said, "We achieved our goal of improving his track speed.  He scored 100% today." Next up Nakamoto will run the Bupa London 10000 road race on April 27 as par...

A late add after back-to-back women's 100 mH NR of 12.62 and 12.60 on Aug. 9 and 15, Hitomi Nakajima made her Diamond League debut with a 12.91 (+0.2) for 7th, her slowest time in a final since March's Maurie Plant Meet in Australia. © 2026 Brett Larner , all rights reserved
