Trans Japan Alps Race

uploading is laborious. reserving for more images
edit – nevermind, got it done.

Looks like a great trip. How many days do you think it would take you to hike?

There is some good images on the NHK Special hompage.

I can’t seem to find the NHK special online :(
Did you get the DVD or watch it on NHKondemand?

I don't know if it is available abroad, though it should be, but you can get the DVD from Amazon Japan.

About doing the whole traverse – I have looked into it before, but it takes quite a bit more research. Just as a reference, map times for the hike from Tateyama in the Northern Alps, to Yarigatake (still in the Northern Alps) are 6 days. Then you still have to count getting from the Japan Sea to the base of Northern Alps (more than 60Km?), climb other quite technical mountain Tsurugi first, get down from Yari and then you are not even in Central Alps yet. Food would be on bigger issue. I would love to do the Northern Alps Traverse. I've climbed Tateyama and Yari on separate occasions, and made really good times there, that was with quite a bit of food weight.

edit – weird, shortened URL didn't work. Here is a full one

Just read about a guy that fast packed running and speed hiking with a 15Kg pack through the South Alps and took him 4 days. I think that is a good time, for sure faster than map time. Again, add at least a marathon or 1.5 / 2? to from the mountains to the sea.

A lot of the areas you will not be able to go significantly faster than map time, just because it gets too technical. On the in between sections or valleys you can of course take half off normal map time if not more.

I really like the idea of multi-day, self supported events- lots of trials and tribulations over multiple days, lots of planning, lots of training, lots of mental focus- all good stuff-thanks for posting!

Ito, very cool, thanks for posting…only 40 miles longer than the JMT but with 2.5 times the elevation gain…no wonder it takes them 5+ days to finish!

Thanks for sharing, Ito.

Looks pretty awesome…heck of a challenge, I'm sure. I'd love to watch the DVD–if anyone in the states finds it, let me know where…

So are there teams? It looks like that in the preparation photo.

Glad it is of interest.

Mike,
I agree, being self supported, doing long days, is really interesting. Also the lack (or almost lack in this case) of aid stations plays a big role. In the movie you see people standing sleeping, waking up and not knowing where they are, people that can't focus their eyes anymore, falling and loosing trekking poles, not knowing where to go anymore. The simple things like what Allen wrote about mentally do really play a part of course, and over these long treks they can really make or brake the trip just as much as the physical side.

Allen,
Thanks for giving me a scale reference to the JMT. It seems like a very interesting and challenging trail.
I think with the Trans Japan Alps like you say it is not so much the distance but the climbing, or not even that, but the technicality/exposure of some of the mountains they cross. There are mountains on there that normally people bring helmets for, and that have you hugging the wall and take half a day to climb up and down. Not saying it's so hardcore, but I find even if I can move quite fast, when the trail gets technical you do slow down, a lot. I think most of the participants in this race take 6 or 7 days.

Adam,
No teams, they all have to wear this white shirt with their number and a reflector in the back. They also carry a GPS tracker and during the race you have life updates on the TJAR website. I don't think they are Spot devices, because those seem to be forbidden in Japan, but something similar.

Found this interesting body composition study of all finishing participants in the 2014 TJAR. It is in Japanese but the summary is in English: The main purpose of this study was to investigate anthropometry and body composition in 26 male ultramountain runners who participated in Trans Japan Alps Race 2014, a multi-stage ultramountain running race over 415 km to be covered within 5-8 days. The second purpose was to investigate the changes in skinfold thickness during the race. Before the race, all participants were examined in terms of body weight, BMI, skinfold thickness at 8 sites and estimated percentage body fat. In addition, the finishers (n=14) were re-examined in the post-race period. The main findings are summarized below. 1. The participants had a mean (±SD) body weight of 62.3±5.1 kg, a BMI of 21.5±1.4 kg/m2, a sum of 8 skinfold thickness of 57.7±15.5 mm, and an estimated percentage body fat of 12.0±2.4%. There were no significant differences in any parameters between the finishers and the non-finishers. 2. The sum of 8 skinfold thickness in the finishers was significantly reduced by 11.3% after the race (Pre : 55.0±13.6 mm, Post : 48.8±12.1 mm), representing a dramatic response in comparison with a previous study that investigated ultramarathon runners in a 100-km ultramarathon race (0.9%).

did the math- those are some pretty light dudes! I'm sure you saw some of the pics of Scott J at the end of his AT, he lost a ton of weight (and he didn't have much to lose to start!)

In what way do you mean? I agree they are pretty light but largely because of length I think. I am 184cm and weigh roughly 10Kg more. But I'm in the same BMI and body fat percentage range as their mean fall into. (Just as a ref between sizing, in Japan I am XL in most athletic clothing, a Medium in Patagonia/Arcteryx)

130-ish lbs is a little light by American standards; my build is not your "typical" runners build- 5'11" 185-ish lbs- more like strong safety build (that's football lingo and not the round kind of football kind) :)

Haha Yeah 185 might put you into potential sumo category from JP perspective.

when I get up a head of stem coming down a mountain, folks tend to quickly move to the side of the trail :) I ran with a friend (he's since moved to AZ) that was 6'5" and about 250 lbs- he was one you definitely got out of the way for!

"when I get up a head of stem coming down a mountain, folks tend to quickly move to the side of the trail " It's that authoritative mustache. Tiny dudes.

"It's that authoritative mustache" Might be the gun.

I hadn't factored those in- could be either one of those as well; "look out Honey- I think it's Doc Holiday running down the trail with gun drawn!" :)

So this is on again!

TJAR 2016, same 415Km course with over 27.000m (≈90.000ft) of gain.

Mochizuki (望月 nr.13), who won the race in 2010, 2012 and 2014, leads again, but this time together with another player.

Wish I had known about this while I lived there. Did Tateyama to Yari twice and a ton of hikes in the Minami Alps. Never made the Chuo Alps. I think good timing would be challenging depending on how busy the trails are,(Tsurugi is pretty busy always as is Yari) and everything in between the mountains. Still seems cool if I’m ever back there again.
