Riding buses with Japanese tourists - long road to the Eiger

Last summer after a long vacationless period I went to the Switzerland for two weeks of pure fun: just Alps and nothing else.
Preparing the trip I used (surprise, surprise) computer to locate best routes, equipment and accommodation advices and any general info. Main and highly accurate source of information was Summit Post.
Looking back I have to say that equipment choice was almost one hundred percent accurate (my back was keeping quite different opinion especially during beginning of the trip).

This is a story about two first days of the vocation (speaking in the language of mountain tourists and climbers: acclimatization period).

This was my first time in Switzerland and my first encounter with the railroad system was pure pleasure: it worked like a Swiss clock. I changed the train after train after train and finally after short stop at Interlaken was in the Grindelwald village, the starting point of my acclimatization hike,

Interlaken Station

The plan was to hike from the Grindelwald (elevation ~1000m) to Kleine Scheidegg (elevation ~2060 m.).
According to the internet guides: easy hike of about 5-6 hours top.

After buying topology map and finding the trail I was on my way.

Almost from the start I started to feel: something strange is happening both to me and to the surroundings.
I was going up on an easy trail but my advance was slow and painful: I was have to rest every 200-300 meters, my 35 kilogram backpack was making me fill like I'm carrying my own weight. The light time-to-time raining following me all day stopped but the clouds started to concentrate into something intimidating.
I suddenly realized: all my near computer information gathering and trail running trainings are not good at all. All this mountain climbers are made from another material, all my planning (new summit almost daily) is just a dream and I have to get a grep of myself, to get down to the Grindelwald and start riding buses with Japanese tourists. Yes, I told to myself this is the place for You: the tour bus.
At this point rain started, and this was a heavy one. Strangely, completely wet and cursing myself I still continued up. Rain stopped and snow started to fall. The water was coming from all directions, both me and the backpack contents absorbed amount of water enough to give life to average desert.

About eleven hours later some strange man entered Klein Sheidegg Railway Hotel; he was looking like some ship crash victim rescued from inhabited island, pools of water marked each his step. Quietly he asked for accommodation. This men was me, my plans for making tent camp ruined, I was not sure if I want to stay at the Alps at all.

Next morning I was out for the trip to the Mt. Lauberhorn, it was just small acclimatization walk listed in my plan. To my surprise I was walking up-hill in steady rate not like yesterday. When I reached my destination (the summit) and double checked the time it was about fifteen minutes less than listed in the Guide book; hard to describe the feeling: it was like winning Olympic race (actually I never won any Olympic race).

Day after I was running on the Eiger trail, but it already another story.
My breakdown nightmare "riding buses with Japanese tourists" not looks to me such a nightmare today but I do met some Japanese climbers near Grindelwald afterward: they placed tents next to my in the camp, I have to say: excellent neighbors.
