Toshinari Takaoka and Eri Yamaguchi on the Secret of the Marathon



Former Japanese men's national record holder in the marathon and Kanebo corporate ekiden team head coach Toshinari Takaoka, 47, appeared at a training and conditioning symposium last week in Osaka to discuss his training during his career as an athlete. His talk revealed the secret of how to successfully tackle 42.195 km.

Before Yuta Shitara (26, Honda) set a new national record at February's Tokyo Marathon, Takaoka's mark of 2:06:16 stood as the Japanese national record for 16 years. In his lecture Takaoka mainly discussed his training for the 2003 Fukuoka International Marathon, a selection race for the 2004 Athens Olympics marathon team. Takaoka focused on five points:
  1. 40 km runs
  2. mileage
  3. utilization of racing
  4. speed work
  5. maintaining a pace of 3:00/km
From August through November that year Takaoka did nine 40 km runs at 3:30/km for a total time of 2 hours and 20 minutes. "At first 40 km runs were painful because I wasn't accustomed to the distance," he said. "But as the number of times I did them increased they became more comfortable and I knew that I was becoming powerful." In his ninth 40 km run Takaoka clocked 14:24 for the split between 30 and 35 km. "I worked on changing the pace on the assumption that the race would get moving near the end," he commented. "I confirmed that my legs would be able to take faster running at that stage."

Keeping in mind the risk of injury inherent in running mileage, Takaoka ran around 1000 km a month at most, competing in track 10000 m races, ekidens and half marathons along the way. "In order to be comfortable running 3:00/km, the fundamental pace of the marathon, it's necessary to develop speed faster than that," he said. "Using other races as speed work helped maintain the leg strength to handle 3:00/km."



Sydney Olympics women's marathon 7th placer and current Asia Pacific University women's ekiden team head coach Eri Yamaguchi, 45, also took part in the symposium. Yamaguchi discussed her use of six-hour solo runs as a buildup to serious marathon training. "In order to ingrain the sensation of that kind of fatigue into my body, I would do them at 5:00/km," Yamaguchi said. The audience of about 150 at the seminar, most of them amateur runners, voiced their shock and surprise as hearing this.

Of the standard 40 km runs that top athletes due in preparation for a race Yamaguchi commented, "I ran about ten marathons. For half of them I did multiple 40 km runs but didn't see any effect. At one point I decided to keep the 40 km runs down to one and instead to increase the number of 20 and 30 km runs, and that's when I started getting results." Yamaguchi's PB of 2:22:12 came relatively late in her career in her ninth marathon. The audience was again surprised to hear that her training had been similar to the kind of approach common among amateurs.

Translator's note: Takaoka finished 3rd at the 2003 Fukuoka International Marathon in 2:07:59 and was not chosen for the Athens Olympic team. More on that race here.

At last month's United Airlines NYC Half, Takaoka's predecessor as national record holder, Atsushi Fujita, discussed his training for his 2:06:51 record with Dathan Ritzenhein, Chris Derrick, Shadrack Biwott and others. Fujita said that off a baseline of mileage around 1000 km per month with regular 40 km runs his final month of training focused around a 40 km in 2:04 four weeks out (3:06/km), followed by 30 km in 1:30 the next week (3:00/km), 20 km in 59 minutes the next (2:57/km), and 10 km in 29 minutes (2:54/km) the week before the race.

Thanks for sharing! To clarify on the volume - was that 1000 km per month, or over a longer period?

'CAS Clears Japan’s Olympic Silver Medallist Ikeda of Doping, Overturns Ban'

https://www.aljazeera.com/sports/2026/10/23/cas-clears-japans-olympic-silver-medallist-ikeda-of-doping-overturns-ban The AIU's missteps in this case cost Tokyo Olympics and Oregon World Championships 20 km race walk silver medalist Koki Ikeda , a Toyo University graduate who competes for the Asahi Kasei corporate team, the chance to represent Japan at a home soil World Championships last year. It is almost unheard of for an athlete to successfully fight a biological passport suspension as Ikeda did, making this a highly significant case. The CAS' press release about its decision stated: "The Panel stressed that the Athlete did not merely assert his position on the ABP abnormalities but adduced very extensive evidence in support of his explanations. In this highly complex case, the evidence brought during the CAS proceedings was far more abundant and specific than during the first instance proceedings with the WA Disciplinary Tribunal, implying the CAS Panel had further ...

Waseda Leads Top 7 Teams Under Izumo Ekiden CR, Ivy League Best-Ever 3rd (updated)

3rd last year, Waseda University scored its first Izumo Ekiden win since 2010, taking almost 2 minutes off the CR and leading the top 7 teams under the old record of 2:07:51 for the complete 6-stage, 45.1 km course. Waseda was 16 seconds back in 7th after the First Stage, but its 2nd runner Ojiro Honda made that up easily and put them 6 seconds out front. A massive 22:56 CR for the 8.5 km Third Stage by Shadrack Kipkemei (Nihon Univ.) dropped Waseda back to 2nd even though its runner Ryuki Suzuki broke the old CR too, but back-to-back CR on the next 2 stages by 1st-year Haruki Niizuma and Shunpei Yamaguchi put anchor Shinsaku Kudo out of reach of the rest of the field. Kudo duly won the 10.2 km anchor stage in 29:00, bypassing a 2:06 time entirely for a new 2:05:56 CR, just under 2:48/km average pace for the complete course. Defending champ Koku Gakuin University struggled a bit in the first half of the race but came on strong in the longer second half with 4th and 5th runners...

Meijo Back With Morinomiyako Ekiden CR for National University Title

The last big dynasty school in Japanese women's distance running with 7-straight wins at October's Morinomiyako Ekiden from 2017 to 2023 and 6-straight titles at the season-ending Mt. Fuji Women's Ekiden from 2018 to 2023, Meijo University came back from a 3rd-place finish last year to win the 44th Morinomiyako Ekiden again, leading almost start-to-finish to set a 2:02:21 CR for the 6-stage, 38.0 km course in Sendai. 12 second back in 2nd after the opening leg, collegiate 3000 mSC champ Nozomi Kondo put Meijo out front with a 12:36 CR for the 4.0 km Second Stage, and the rest of the team never looked back. The biggest threat to a Meijo win was on the 9.2 m Fifth Stage, where this year's collegiate 10000 m winner Sarah Wanjiru from last year's runner-up Daito Bunka University started 50 seconds back from Meijo 1st-year Mao Kimura . In taking the 10000 m title Wanjiru had outrun Kimura by over a minute, but today Kimura was a revelation, strong and smooth out fr...
