Hakone Ekiden Qualifying Race Start Time Moves an Hour Earlier to Cope With Rising Temperatures


On Mar. 25 the KGRR, organizers of the Hakone Ekiden, announced the start time for mid-October's 102nd Hakone Ekiden Yosenkai qualifying half marathon in Tachikawa, Tokyo will be changed from its traditional starting time of 9:35 a.m. to 8:30 a.m. as a measure against rising temperatures. The KGRR explained, "We have explored what options we have to maximize the safety of our athletes from the effects of global warming. With that in mind we have decided to move the start time earlier to reduce the risk from heat."

At the Yosenkai half marathon schools may run up to 12 team members, with their first 10 finishers scoring based on their combined finish times. With places at the world's biggest road race on the line competition is fierce and the young student athletes push their bodies and minds to their absolute limits.

Last year's race on Oct. 19 had unseasonably hot weather that turned into a battle of attrition. At the 9:35 a.m. start it was 23.2˚, rising to summertime temperatures over 25˚ during the race. Overall performances clearly showed the less than ideal conditions for a half marathon. Winner Rikkyo University's total time was 10:52:36. A year earlier when the temperature at the start was 15.8˚ that would have put them at 25th. Final qualifier Juntendo University in 10th would have been 34th. Both schools' times were the slowest since the distance of the Yosenkai was increased from 20 km to the half marathon in 2018.

Many athletes struggled seriously in the final kilometers of the race as temperatures rose. Tokai University 3rd-year Rohoman Shumon collapsed meters for the finish, one of 10 athletes who failed to finish. Tokai head coach Hayashi Morozumi later explained, "Rohomon suffered severe heatstroke."

The date for this year's Yosenkai has yet to be announced, but it is expected to be held in mid-October like usual. The announced earlier start is expected to produce a safer, more competitive, high-level race. Susumu Hara, head coach of 2025 Hakone Ekiden champion Aoyama Gakuin University and chair of the KGRR's Hakone Ekiden Planning Committee, commented, "We will continue to introduce reforms from the standpoint of putting the athletes first."

Translator's note: If held on its usual weekend, the Yosenkai will be over a month after the Tokyo World Championships women's and men's marathons. Good luck to everyone running there.

Good move, they maybe could have started at 8.00 am like Hakone (if memory serves me right) Ekiden but it's a solid move to help runners.

M.I.A.

Sorry to have been silent for a while. JRN associate editor Mika Tokairin  was in Taiwan for Ironman Penghu, where she won her age group to qualify for Kona for the first time. Right after that we moved for the first time in 14 years, and immediately after that I headed to the U.S. to help Keita Sato  get settled in his new training base in Flagstaff. We'll be resuming normal operations shortly with a big roundup of results over the last 2 weeks. Brett Larner

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.
