This is getting a little creepy…

Filed under: — stan @ 11:47 pm

This is so consistent that it’s getting a little creepy. We’re three weeks into stair practice at the Aon building for this year’s stair climb. And every week, the same two things happen:

  • On Tuesday, I beat my previous best time by an average of seven seconds;
  • On Thursday, I go two seconds slower than I did on Tuesday.

This has happened three weeks in a row now, and I find it remarkable that it’s so consistent. On the other hand, I find it very hard to visualize taking seven seconds off my time every week from now until the end of March. That would have me doing the practice in 8:50 on the Tuesday before the race. And that would put me at a pace that’s just not something I think is possible. So my streak is going to end. But let’s see if I can keep it going for a couple more weeks. That would be really great.

Once again, I spent the whole train ride downtown dreading what I was about to do. But I had a useful mental diversion this time. I’d worked out a way to switch leading legs on the first and third major portions of the stairs. This is the part where there is about 16 stories in a row of 22 steps per floor, divided into two 11-step flights. This works out to five double steps and one single on each flight, and 12 footfalls per floor. This means that the left and right leg are working in a 6:5 ratio, and that unevenness builds up after a few floors. So I’ve been doing a little skip-step every few floors to switch which leg starts off, so as to even out the load. But today, I wanted to try a new scheme that I thought might be a bit smoother and not break my rhythm. The plan for today was to switch legs on every even-numbered floor. I figured that would be easy to remember. Normally, my rule is that if I do a single step onto the landing, then I pivot and start the next flight with a double. And if I do a double onto the landing, I start the next flight with a single. The difference this time is that I was going to reverse that on every even-numbered floor. On those floors, if I did a single onto the landing, I turned and started off with a single. And if I did a double, I did a little reach and started the next flight with a double. This had the effect of switching which leg was doing the two singles per floor. I got confused a couple of times on the way up, but I think with a little practice, I can probably do this without having to think too hard. And I did notice that it helped a lot to even out the load on each leg.

I also paid attention to the mechanical floors again. This time, I only counted two that had more than the standard 22 steps. Just from 22 to 23 and 42 to 43 were 24 step each. The others were all 22.

All this thinking about stepping patterns and such really helped to keep my mind off the usual “What-the-HELL-was-I-thinking-doing-this-again”. This was a good thing. when I got to 57, I looked at my watch and saw 9:40, and I knew I was on track for a good time. So I managed to put on a little burst of speed to make it to 60 and do my usual face-plant on the floor. But when I looked at my watch, it said 10:01.72, which is only 0.02 seconds off being exactly two seconds slower than on Tuesday.

Remarkable. But I’m not complaining one bit. This is great!

What I said last week…

Filed under: — stan @ 11:03 pm

It’s practice time at the Aon building in downtown Los Angeles, and like I’ve been saying a lot lately, “this is great!”

I was really not looking forward to this today. But I didn’t want to miss the chance to practice on the actual stairs where we will be racing in March. So I figured that I’d use this chance to pay attention some more to the layout of the stairs, and practice switching leads on the first and third sections of the stairway to balance the loading on each leg.

I paid close attention this time, and I realized that in the practice climb from 4 to 60, there are only three floors that are larger than the standard of 22 steps per floor. They are from 21 to 22 and from 41 to 43. Those three are 24 steps, where all the others are 22. It’s interesting how I’d noticed that the mechanical floors were larger than the standard, but at the same time, they seemed like they were a lot bigger. Two extra steps per floor really isn’t all that much. I think the illusion comes from the fact that from 20 to 24 and 40 to 44 the steps change and go from counter-clockwise to clockwise. So each of those interludes feels like one big floor, even though its actually several individual floors.

This also allows me to compute the number of steps in the practice climb:

56 x 22 = 1,232
1,232 + 6 = 1,238 steps
1,238 x 7.5 = 9285
9285 / 12 = 774 feet of climbing

Knowing the layout of the stairs has helped me to sort of mentally break up the climb into smaller chunks, which makes it easier to deal with.

So today, I was just going up the stairs, not really trying to set a blazing pace. I noticed that on the first section that it only took about four or five floors before I noticed that one leg was working much harder than the other. So I remembered to do a little stutter-step about every four floors to switch which leg was leading. That was also a useful mental diversion.

When I got to 50, I had a quick look at my watch and saw that I was on track for a good time. So I kept going, and managed to put on a little burst of speed from 57 to 60. I stumbled out of the stairs and flopped on the floor. When I looked at my watch, it said 9:59.74. This is the first time I’ve been under 10 minutes for this climb, although by the rules I’ve established, I really have to round that to an even 10 minutes. Still, this is 10 seconds faster than my previous best that I did last week. Nothing not to like there.

Working out my power production gives:

9285 x 2.54 = 236 meters
236 x 77 x 9.8 = 178,086 joules
178,086 / 600 = 297 watts
297 watts = 0.398 horsepower

Not too bad.

On the train home, I worked out another possible way to switch leading legs between floors. One that will not require any fancy footwork. I’m going to try that out on Thursday.

This is great!

Living in a Modern Way

Filed under: — stan @ 7:40 pm

Since today is a holiday, Kathleen and I went over to LACMA to see “California Design, 1930–1965: Living in a Modern Way“. We’d seen a little bit of this last fall when we saw the Tim Burton exhibit, and we’d been meaning to come back to see it.

We went there a bit early, just on general principles, and that turned out to be a good thing. Today was a Target Free Holiday Monday, so the museum was free, and it was packed. Still, we had a good time looking at all the odd objects in the exhibit, from the Airstream trailer that looked like an aluminum lucha libre mask, to a 1938 digital clock. We also saw a propaganda poster that looks just like things we see today, an original 1959 Barbie doll, and a video with Walt Disney demonstrating how a nuclear bomb works with mouse traps and ping-pong balls. It was a weird assemblage of stuff.

After that, we wandered around the rest of the museum. We went looking for Magritte, since I like surrealism. We also saw the big “Metropolis II” installation. That had little cars and trains zooming around the giant model city. It was kind of hypnotizing to watch, although it was kind of loud.

It was a fun afternoon.

Three hours on Sunday morning

Filed under: — stan @ 4:06 pm

On Friday, the L.A. Times had an article about “Three Weeks in January“, which is an art installation on the wall outside LAPD headquarters in downtown Los Angeles. It’s the brainchild of Suzanne Lacy, who originally created it in 1977 to raise awareness of rape in Los Angeles. The installation features a map of the city, with reported rape cases plotted, as well as a continuous storytelling soundtrack with people telling their rape stories. It’s all rather disturbing and haunting, which I guess is the point. So of course, when I saw this, I thought it would make for an interesting riding destination for Sunday morning.

It was kind of cold and cloudy, with the forecast saying there was a slight chance of rain. But the route we were taking is one that is never more than about 2 miles from the nearest Metro Rail station, so we had a bailout plan, if it became necessary.

We took the direct way downtown, down Huntington Drive and Main St. We stopped off to look at the art project for a bit before continuing on through downtown. Looking back, we got a good view of all the skyscrapers, and Jeff and I both took a moment to remember all the pain of climbing the stairs in all those buildings. Then we turned on Adams to head west for a bit. It started to rain a bit then, but it was very light, and it only went on for about 10 minutes. So we just kept on going.

I found a little back way from West Adams up to Larchmont. It was a little roundabout, but the streets were quiet, and we had lights to cross all of the major streets, so it worked well. Our snack stop was at Noah’s Bagels in Larchmont.

The route home went up Benton Way in Silver Lake, which is a nice, steep little hill. Always fun. Then we rode across the L.A. River and up Eagle Rock Blvd. That was when Silvio started having trouble with his chain skipping. We stopped to try to adjust it a bit, but in the end, it turned out that one of the pins was coming loose, and the chain was about to break. So he had to ride very carefully the rest of the way. He managed to make it up the Colorado hill, and after that, he turned off to go visit a bike shop.

It was a pleasant ride.

41 miles.

More fun on the stairs

Filed under: — stan @ 7:02 pm

Since I had to take Lucinda to art class after work today, I went downtown at lunchtime to do the Aon building practice climb. On Tuesday, I’d done my best time yet, as well as made some useful observations about the stairs and how to climb them more efficiently. So today I wanted to try implementing those ideas and see what happened.

At the beginning, I experimented with doing a quick stutter-step on each main floor landing to switch which leg was leading off on each floor. But this quickly turned out to be too much trouble. So I fell back to switching sides about every five floors. That’s long enough to start to notice that one leg is working harder than the other, so it’s a good time to switch.

The stairs change at floor 20, but it turns out that it’s still 22 steps to get to 21. The mechanical floor starts just above 21, so from 21 to 24, it’s 24 steps between floors. There’s also a short hallway, and several fire doors. Those will be propped open on race day, so they don’t cause much trouble.

On the middle section with the wide landings from 24 to 41, I deliberately took an extra quick step on most of the landings to switch which leg led off on every floor. I figured this wasn’t a problem, since I had to cross the big landing anyway, and I can do it with one long step or two short quick steps, and the time is about the same.

When I got to 50, I took a look at my watch, and it said something like 8:30, so I knew I was pretty much on the same pace as on Tuesday. I was hoping to beat my time today, and I managed to pull out a little sprint from 57 to 60. But after I finished gasping for air and looked at my watch, I saw that I’d gone two seconds slower. Still, that’s not terribly significant here. I’m pretty consistently doing times that seemed impossible last year.

As I find myself saying a lot these days, “there’s nothing not to like about that.”

I think it’s time to say again, “This is great!”

Filed under: — stan @ 10:28 pm

It’s Tuesday, and that means stair practice at the Aon building in downtown L.A. As always, I rode the train there, and as always, I was dreading it all the way there.

I got to the building and signed in. Then I went to the stair entrance on the 4th floor to get ready. I had decided that I was going to try to be more conscious of the steps today, and try to see how much larger the mechanical floor are, as compared to regular office floors. I figured that would give me something else to think about besides, “What the HELL was I thinking coming here and doing this again.

This building was built in the early ’70s, and the steps are 7.5 inches each. Regular office floors have 22 steps between them. For most of the building, these are in the form of two 11-step stairways with a landing and 180-degree turn between them. I’ve worked out how to do the ‘one foot on the landing’ turns, so each 11-step flight is basically six footfalls, twelve for one floor. And I noticed that that means that if I start off with my right foot, the fact that it’s an even number of footfalls per floor means that I’ll always be starting off on my right foot. But because it’s two flights, each with an odd number of steps, there’s double steps, with one single at the end of each flight. And it worked out that the single step was always on the same leg. In practical terms, that means that of the 22 steps I have to lift my body for each floor, one leg is doing 12 of them, and the other leg is doing 10. And that difference adds up after 10 or 20 floors. So I figured out to do a little stutter-step about every five floors, so that I’d switch which leg was leading and having to do more work. This may have helped even out the load on each leg. In any event, it kept my mind occupied and thinking about something other than how much all this stair climbing hurts.

I also noticed one other thing about this. The middle portion of the building, from 24 to 41 is a bit different. There are still 22 steps per floor, but they are divided up with 10 steps, a landing with a 90-degree left turn, three steps, another landing, and then 9 steps up to the next floor. So the landings on the floors are big, and there’s no way to do a pivot turn. You pretty much have to take an extra step. But because it’s easy to do double steps with 90-degree turns, it ends up being the same 12 footfalls for each floor. But one of those footfalls is a non-climbing one on the big landing. And so you end up with 11 climbing steps per floor, six on one leg, and five on the other. And if you don’t do a stutter-step every few floors, one leg is doing significantly more work than the other. And that’s bad for business.

The other thing I wanted to pay attention to was the mechanical floors. These are where they keep the elevator motors, air conditioning blowers, and other such things. I’ve always had a sense that these floors are a little taller than regular floors. So I counted steps when I got to the first one at 20. And it turned out that from 20 to 24, the floors were 24 steps apart. That’s not a huge difference, but it is a little bit more. And the mechanical floors from 41 to 45 were also 24 steps each.

The top of the practice climb is at 60, and I stumbled out of the stairwell and flopped down on the floor. I was very pleased to see that my time was 10:10, which is a full 8 seconds faster than my previous best time.

After recovering for a bit, I walked up the stairs the rest of the way to the roof door, just to see how many steps there were. It was 24 steps to 61, and 28 to 62. Then there were 10 steps more to the roof door. After that, there’s just the last flight up to the roof, and I didn’t open the door to count them, since the guards at the building have been very nice to us, and I don’t want to cause trouble. But that last flight is probably something like 12 or 16 steps.

And that’s my report from the stairwell. Back to you in the studio…

Big ideas that just never caught on

Filed under: — stan @ 1:45 pm

Today’s bike club ride was an architecture tour of sorts. The L.A. Times had an article last week about Wallace Neff and his ‘bubble houses’. This was an idea for a way to build circular dome buildings quickly and cheaply. The article said that a lot of bubble houses were built in the 1940s and ’50s, but that only one still exists today, and that one is on Los Robles Ave in Pasadena. This got me thinking about a theme for the ride, and I thought of another sort of round house: the geodesic dome. This was another big idea that just never really caught on. And I also knew where there is a dome home, just below the Hollywood sign in Hollywoodland. So, armed with a theme, I made up a route.

We rode out across Eagle Rock and then over the L.A. river into Silver Lake and Hollywood. Then we turned up Beachwood Canyon and the fun started. The road up the ridge on the side of the canyon is very steep and winding. I tell everyone that I guarantee they’ll be seeing stars by the time they get to the top.

After a brief rest and regroup, we rode along the ridge to the geodesic dome home. We looked at it a bit before continuing on to the Hollywood sign. Since we worked so hard to get up there, we figured we should go see it while we’re there. Then it was down the other side to Lake Hollywood, and the other steep hill to get over into Burbank.

We stopped for snacks at Priscilla’s, and then headed back down the L.A. river bike path. The route back took us through Highland Park and South Pasadena until we got to the bubble house on Los Robles Ave. It’s an odd-looking thing, but it’s a little bit of history, so it was interesting to see.

It was a nice day, and all together a nice ride.

47 miles.

Why do I keep doing this?

Filed under: — stan @ 8:11 pm

Today was the second practice at the Aon building in downtown Los Angeles. On Tuesday, I’d set a new personal best for the practice climb from 4 to 60. But, since practice is a good thing, I’m back again.

As always, I was dreading it all the way downtown on the train. I was dreading all the way up to the moment I pushed the button on my watch and started up the stairs. After that, I was in too much pain to be thinking about dreading it.

For some reason, there haven’t been many people coming out to the practices yet. So all the way up, I only saw one other person. It’s hard climbing like that, all alone. I like having people to pass.

At 60, I stumbled out of the stairs and took a couple of pictures. My time was 10:20, which is two seconds slower than on Tuesday, but still faster than any of my practice times last year. So there’s nothing not to like there.

I also did some actual measurements on the stairs. The steps at Aon are 7.5 inches tall. They say the full climb is 1,377 steps, and doing the math gives:

1377 * 7.5 = 10328 inches
10328 / 12 = 860 feet

This agrees well with the published height of the building as 858 feet. Based on this measurement, it seems that the standard stamped-steel staircases at Wilshire-Figueroa, Wells Fargo, and One California Plaza are all 7 inches per step. I’m told that this is the current building code value, and the Aon steps are only steeper because it was built back in the early ’70s, and the code was slightly different then. So all this time, it’s not been our imagination that the stair climb up the Aon building is harder than the others. Good to know.

Well, that’s it for this week. Back at it again next Tuesday.

Here we go again…

Filed under: — stan @ 10:00 pm

I told Lucinda we could go to Disneyland once before school starts up again next week, so today was the day. There were five of us this time. Myself and Kathleen, Lucinda, and Kathleen’s daughters, Trinh and Melissa. As you might expect, once we got to Disneyland, Kathleen and I were on our own, and only saw the girls a couple of times in passing throughout the day.

Our day was fun. It was a bit on the crowded side by our standards, but we still managed to ride Space Mountain twice, Thunder Mountain four times, Matterhorn twice, and over at California Adventure, we rode California Screamin’ twice together, and I did it three more times in the single-rider line. Which brings my total up to something like 86 rides on that roller coaster. Nope, I still don’t believe it either.

At one point, California Screamin’ broke down, and we got to watch them evacuate the train from the top of the big hill. I’m glad we weren’t on it then. I don’t mind riding the train down that hill, but I think walking down it on the steps would give me the willies.

At the end of the day, we met up with the girls, and we went for our usual dinner at the Jazz Kitchen. From the sound of it, they managed to do a lot today, too. So overall, the day was a success.

First stair practice of 2012

Filed under: — stan @ 9:27 pm

They’re starting stair practice early this year. Today was the first session in preparation for the Aon Tower stair climb on March 31. It was the usual course, from the 4th floor to the 60th at the Aon building in downtown Los Angeles.

I’ve done this particular stair climb many, many times now, since I did all the practice sessions last year and the year before. But somehow, it never gets any easier. On the train to downtown this evening, I was thinking that I really didn’t want to do this. So I decided that I’d just do it at a comfortable pace, not trying to break any records. Still, I’m going faster now than before. Today’s time was 10:18, which is a good three seconds faster than my best practice time last year. So I really can’t complain.

At the top, I took a few minutes to catch my breath and take a picture, then I took the elevator back down. It was fun. At least as much as the most painful thing I’ve ever done can be called ‘fun’.
