昨日に引き続き、今日も朝サイのヒルクライムへ。

平岩駅まで車で移動し、準備を整えて6:30スタート。まず目指すは大峰峠。うちの記録には何度も登場している、あの「レッドカーペット」のコースです。

レッドゾーンの激坂はもちろんですが、実はそこへ至るまでのほとんどが蛇行の連続。それだけ斜度がきついということなんです。そしてこの道は車がほとんど通らないのに道幅はしっかりとある。蛇行にはもってこいだぞ!と、僕は勝手に思っておるわけです。

ちなみに蛇行にも、上手いと下手があるわけなんです。当然、僕は自称・蛇行上手(笑)。

これ、実はスキーのターンとまったく同じ要領なんです。スキーなら板が進みやすいように、自転車ならタイヤが転がりやすいように、と身体の位置をポジショニングするわけなんです。力で無理やりねじ伏せるのではなく、円弧の理屈で前へ進んでもらう。そうするとタイヤはスタックせずに、自然に転がり続け、その転がりの中で少しずつ少しづつ標高を稼いくという仕組み。

蛇行してる時のイメージは、あの無限大の「∞」マークなんですね。

僕がヒルクライムをあまり苦に感じないのは、この効率的な蛇行を身につけたから。クルクル回してさえいればそのうち到着するさ…とそんな感覚でいつも登っているわけなんです。

逆に交通量の多い道路で蛇行が封じられたならば、僕はあっさりと降りて歩くかもしれません。それくらいこの蛇行は僕の武器なんです。

ちなみに当スクールでは自転車プログラムも用意してあります。受講希望の方はぜひどうぞ。同時に、ダウンヒルのカーブで絶対に膨らまない身体の使い方もお伝えできます。

…と、前置きが長くなりました(笑)。

今回は大峰峠からそのまま小滝へは下らず、途中から高浪の池へ登り返し。高浪の池は雪の季節にも何度かスキーで訪れた場所。

そこからはダウンヒルして、明星山を間近に見上げられる展望台へ。

「デカいなぁ…。迫力あるぅ〜〜。」

実はこの山、というかこの一帯は、はるか昔に赤道付近から移動してきた地層なのだとか。以前アニメーションで見たことがありました。

南のサンゴ礁が海洋プレートに乗って運ばれ、大陸プレートに沈み込む。そのとき軽い石灰岩は沈み込めず、陸側に削り取られて積み重なっていく。その積み重なったものが目の前の明星山。

なるほど…。言われてみると、確かに「積み上がった感」ある〜〜。

そんなことを思い出しながら小滝まで一気にダウンヒル。

さて、ここからどうしましょ?

糸魚川方面へもうひと登りするか。国道を走るか。もう一度大峰峠を登り返すか。それともトラックにビビりながらトンネルの国道で平岩へ戻るか…。

いやいや、それより何より、もう十分暑い(笑)。

ということで、あっさり小滝駅から輪行することに。次の電車まで約1時間あったので、駅横にある発電施設の展示をじっくりと見学。

「へぇ〜、こんな分厚い鉄板を丸めてリベットで留めているの!?」

昭和初期、当時最高峰と言われた鋲接(びょうせつ)技術。溶接との端境期だったのでしょうかね。現物を見ると、その迫力に思わず見入ってしまいます。

定刻どおり電車が到着。210円払って1区間だけ乗車し平岩駅へ。

時刻は9:30。

かなり暑くなっていましたが、「葛葉峠ならすぐそこだし、元国道だから斜度も緩い。その先がどうなっているのか見てみたい。」

そんな思い付きでさらなる延長戦へ。

巨樹「ボッカ栃の木」は今日も健在。会えて嬉しかったです。

葛葉峠の先はゲートで閉鎖されていましたが、「塩の道」は通れるようになっておりました。

そこからビューッと下って白馬大仏へ。経年が生み出す迫力、というかどこか妖気すら漂っている気配アリ。

10:30、車に到着。即クーラー全開。火照った身体をゆっくり冷やしました。

今回は、短い時間ながらも走りも景色も地質も歴史も楽しめた、見どころ満載の朝サイクリングとなりました〜。

Continuing from yesterday, I headed out for another early morning hill climb ride.

I drove to Hiraiwa Station, got everything ready, and rolled out at 6:30 a.m. My first destination was Omine Pass, the famous "Red Carpet" climb that has appeared in my ride reports many times.

The brutally steep Red Zone is well known, but in reality, almost the entire climb leading up to it is full of switchbacks. That alone tells you just how steep it is. The best part is that almost no cars use this road, yet it's wide enough to ride comfortably. In my opinion, it's the perfect place to practice switchbacks.

By the way, there's definitely such a thing as good and bad switchback riding. Naturally, I consider myself pretty good at it!

The technique is actually exactly the same as making turns on skis. On skis, you position your body so the skis can glide naturally. On a bike, you position yourself so the tires can roll as easily as possible. Instead of forcing the bike with brute strength, you let the geometry of the arc do the work. That way, the tires never bog down?they just keep rolling, and little by little you gain elevation almost effortlessly.

When I'm weaving up the mountain, the image in my mind is the infinity symbol (∞).

I think the reason I don't mind climbing hills is because I've learned this efficient way of riding. As long as I keep tracing those endless curves, I know I'll eventually reach the top.

If I had to climb a busy road where weaving wasn't possible, I'd probably get off and walk. That's how important this technique is to me.

By the way, we also offer cycling programs at our school. If you're interested, you're more than welcome to join us. I'll also show you how to use your body so your bike never drifts wide through downhill corners.

...Anyway, enough of the introduction!

This time, instead of descending directly to Kotaki from Omine Pass, I turned uphill again toward Takanami Pond, a place I've visited several times on skis during the winter.

From there I enjoyed a fast descent to the viewpoint where Myojo Mountain rises right in front of you.

"Wow... it's enormous. Absolutely breathtaking."

I once watched an animation explaining that this mountainーor rather this whole areaーactually originated near the equator millions of years ago.

Ancient coral reefs rode north on an oceanic plate toward the continent. As the plate subducted beneath the continental plate, the lighter limestone couldn't sink with it. Instead, it was scraped off and piled up along the edge of the continent.

And that enormous pile eventually became the Myojo Mountain standing in front of me.

Now that I know the story, I can almost see that feeling of everything having been stacked on top of itself.

Thinking about that, I enjoyed the downhill all the way to Kotaki.

So... what next?

Should I climb toward Itoigawa? Ride the national highway? Climb all the way back over Omine Pass? Or brave the tunnels full of trucks on the highway back to Hiraiwa?

Then I realized...

Wait a minuteーit's already getting seriously hot!

So I quickly changed plans and decided to catch the train from Kotaki Station instead. I had about an hour before the next train, which gave me plenty of time to explore the small hydroelectric power exhibit beside the station.

"Wow... they rolled steel plates this thick and fastened them together with rivets!?"

It was riveting technology from the early Showa era, considered state-of-the-art at the time. Perhaps it was the transitional period before welding became common. Seeing the actual structures in person, I couldn't help but admire the craftsmanship.

Right on schedule, the train arrived. I paid 210 yen for a one-stop ride back to Hiraiwa Station.

It was 9:30 a.m.

It was already getting quite hot, but then I thought, "Kuzuba Pass is just around the corner. It used to be the old national highway, so the grade is gentle. I wonder what's beyond it."

And just like that, the ride went into overtime.

The giant Bokka Chestnut Tree was still standing proudly. I was genuinely happy to see it again.

Beyond Kuzuba Pass, the road was blocked by a gate, although the historic Salt Road remained open to hikers.

From there I enjoyed another fast descent to the Hakuba Great Buddha. Time has given it an incredible presenceーalmost an eerie aura.

By 10:30 I was back at the car. The air conditioner went on full blast as I cooled down my overheated body.

It wasn't a long ride, but it was packed with highlightsーgreat climbing, beautiful scenery, fascinating geology, a bit of history, and plenty to enjoy. Another wonderful morning on the bike.
