Lake Senba Running Path to be Made Exactly 3 km

The Lake Senba walking and running path in downtown Mito, Ibaraki Prefecture will be undergoing construction work beginning this summer to extend the loop from 2986 m to precisely 3000 m. The current length was the result of a systematic measuring error which gave the popular loop a bad reputation among the local running community, who felt the course left them with "14 meters of dissatisfaction" with their workouts. The city of Mito plans to combine the correction with a nearby roadwork project, with work on the running course expected to last until March next year and cost a total of $150,000 U.S.

The Mito municipal government spent six years building the Lake Senba loop from '96 to '02, only to discover Rikuren rules specifying course measurement standards shortly after completion of the path. The Rikuren requirements state course distance must be measured 30 cm from the inside on a corner. Mito measured the 5 m-wide path down its center, resulting in an error of 14 m when the course was remeasured using the Rikuren protocol. Correcting the error to make the loop exactly 3000 m will help facilitate the various races which take place on its course.

An area man, 69, who walks on the Lake Senba course every day commented indifferently, "I don't think anybody who walks here cares about 14 m." Another local man, 56, who runs at Lake Senba in training for marathons, said, "This is going to make it so much easier to take my splits!" in obvious joy at the news.

Learning from their mistakes, the city will have Rikuren course certification officials oversee the construction work this time to ensure the new loop is accurate.

Everything You Need to Know About the 2026 Hakone Ekiden

The Hakone Ekiden is the world's biggest road race, 2 days of road relay action with Japan's 20 best university teams racing 10 half marathon-scale legs from central Tokyo to the mountains east of Mount Fuji and back. The level just keeps going higher and higher , hitting the point this year where there are teams with 10-runner averages of 13:33.10 for 5000 m, 27:55.98 for 10000 m, and 1:01:20 for the half marathon. It's never been better, and with great weather in the forecast it's safe to say this could be one of the best races in Hakone's 102-year history, especially on Day One. If you've seen it then you know NTV's live broadcast is the best sports broadcast in the world, with the pre-race show kicking off at 7:00 a.m. Japan time on the 2nd and 3rd and the race starting at 8:00 a.m. sharp.

Kuroda Conquers the Mountain to Give Aoyama Gakuin the Hakone Ekiden Day One CR Again

After a wild New Year Ekiden corporate men's national championships yesterday that saw new CR on 6 of the race's 7 stages and a 7-second miss on the one that wasn't broken, Day One of the 102nd Hakone Ekiden more than lived up to what the pros had done 24 hours earlier. Only one runner, Chuo University 's Yamato Yoshii in 2022, had ever broken 61 minutes for the 21.3 km First Stage , but when Chuo's Daichi Shibata took it out on CR pace the entire field went with him. It took a while for Ageo City Half winner Rui Aoki of Izumo Ekiden champ Koku Gakuin University to move up to the front, but when he did it was decisive. Aoki crushed the CR in 1:00:28, 59:54 half marathon pace, and behind him the next both Shibata and the Kanto Region Student Alliance select team's So Kawasaki from Tsukuba University also went under Yoshii's old 1:00:40 record. 4th through 8th broke 61, setting the tone for the rest of the day. Chuo, KGU, last year's top 2 Aoyama...

GMO Wins First National Title at Era-Changing 2026 New Year Ekiden

Things have really been coming up fast the last year or so in Japanese distance running, but even so this year's New Year Ekiden really felt like the era has changed. GMO took the lead on the second of the race's 7 legs and went on to take over 2 minutes off the overall course record for the 100.0 km course, winning its first national title in 4:44:00. En route 6 of the 7 legs had new CR, a lot of them with multiple people breaking them, and the only leg that didn't, the 12.3 km First Stage, saw Shunpei Tomita of Logisteed run 34:23, only 7 seconds off the CR held by sub-27 Kenyan Martin Mathathi . The level at the collegiate Hakone Ekiden keeps going up up up , and that showed here as 3 of the new stage CR were set by guys in their first season in the corporate leagues who were some of the biggest stars at Hakone last year. Aoyama Gakuin University grad Aoi Ota sneaked in 1 second ahead of Toyota 's Jin Yuasa to set a 46:00 CR on the 15.9 km Fifth Stage. Collegi...
