Well, today I took part in the local “Round the Bays” event. Thousands of people gave up their Sundays to run or walk en mass along the roads that circle the bays of this city. Many other cities have similar events. Participants can choose to run or walk or something in between, over distances ranging from 6.5km to a half marathon (just over 21km). I chose the middle 10km option.

As I was walking by myself this year I caught the train to town and therefore arrived before the runners who chose the longer distance had been started off. The start area was filled with people stretching various muscles and sinews, some contorting themselves strangely and probably uncomfortably.

There were groups stretching in synchrony and individuals doing their own stretching exercises. I suppose that these people would be pushing their bodies pretty hard and really needed to “loosen them up”. There were others, like myself, just wandering around, having presumably decided that they would not be pushing themselves that hard and such vigorous loosening up was not necessary!

Since the race bibs were colour coded it was easy to tell which event someone was entered for. Young and old were represented and of course all ages in between. Some were probably even older than me! All frames from skinny to very much over large were represented.

As the half-marathon was about to kick off, all participants were called to the line. Well, actually, the fastest, the “elite” were called to the line, and people were asked to place themselves in order of fastest at the front, slowest at the back. To assist with this some of the organising people held notices on poles with an estimated finish time,  so that slower starters would not impede the faster, or to put it another way, the slower participants would not be trampled by the more speedy.

There was the usual “10, 9, 8,….” countdown and someone fired a maroon, and off they went, disappearing down the road. An event like this causes massive disruptions as roads are closed for obvious reasons.

Each runner or walker has attached to his or her shoe a little tag, which records the time that they cross the start and finish lines. As a consequence of this the participant can delay his or her start if the start line is too crowded. In fact, since the pack of runners and walkers extended 30 or 40 metres back from the start line, the shoe tags meant a participant could cross the start line minutes after the start and still get an accurate time for the journey.

Many people did in fact decide not to be too prompt to cross the line and there were queues for the loos right up to and after the official start. However, eventually everyone was away, though participants continued to trickle through the start for a while.

A bit later they called for the 10km runners and walkers, and again, the fastest were asked to go to the front and the slower people were urged to stay at the back. Once more the maroon went off and people started passing the start line. I held back because I knew that there was always congestion at the start line, even with the shoe tags helping to spread the rush.

When I came to cross the line there was a slight slowdown, but I’d fortunately judged it quite well, and we were away. I’m always wary of starting too fast and getting tired at the end so I didn’t try to push through the throng too much, but it spread out pretty quickly.

The first part of the course is actually a block away from the waterfront, past Te Papa, the national museum, and only joins the waterfront after a few hundred metres. The rest of the course though follows the coast quite closely, first going out to a headland and then back into the next bay around the harbour.

Of course, with thousands of people on the road, it is closed to traffic, but people don’t seem to mind this. Most car parks were empty, both those on the side of the road and those on private properties, so locals seem to have made plans to cope with the road closures.

After a couple of kilometres I put on some pace and started passing a fair number of other walkers. Others with similar plans but fitter bodies were also passing me, I should mention!

With thousands of people thundering up the road, there were no bicycles or skateboards, but there were a few runners without race bibs who had either not heard about the event or who had decided to run along the course anyway. Along one part of the Parade there is a quite large fountain, and this was playing as we made out way past.

The second stage of the course winds round some small bays which border much larger bay. We lost the view of the city as we looped through these bays. Quite a few of the local residents were watching from their balconies as we passed. A few had hoses out and offered cooling showers, but the day was not too hot and they had few takers.

And then we were 500m from the finish! But we had only travelled just over 5km! So we took a left and travelled around 2.5km and the same back again. This loop took us past the airport and several flights blasted off as we passed. It can be quite loud and surprising down on the road as the runway is elevated, so you can see or hear them coming until the last minute.

As we went out, we were passing the half-marathoners and the faster 10km runners who were on their way back, travelling the last few kilometres to the finish. The turning point was a great relief and I knew that there was not much left to do. When I finished the out and back the course merged with the course that the 6.5km participants followed (and which we followed up to the point where we followed the loop). Many of the 6.5 participants had already reached that point.

So eventually we all, half-marathoners, 10km runners and walkers and 6.5km runners and walkers, arrived at the finish pretty much at the same time! The result was not chaos though as people were efficiently passed through the channel, given a banana and a drink, and issued into the wider park behind. Oh, and I was relieved of my shoe tag too.

The park was crammed with participants and their “support teams” and various booths set up for participants of various teams, there was a band on stage and much going on. But for me it was simply a matter of catching the shuttle back to the station to get home, having had a great time.

The whole event was smoothly organised by Sport Wellington, sponsored by Cigna Life Insurance, and supported by Wellington City Council and Wellington busses and trains, and many others. It was a thoroughly enjoyable event.

How do I get from A to B?

We had reason to visit another suburb today. It wasn’t until I was sitting waiting for some traffic lights to change that I thought about how I was navigating from home to destination.

We just got into the car and drove there. I didn’t consider the route in advance, and it seemed that I just pointed the car and we got there. Obviously I knew the way, as we had been there or through there a number of times in the past. But I didn’t have the destination in mind from start to finish, at least not consciously. I’m not sure that I had it in the forefront of my mind at all.

I knew that it was in that direction though, and that did not leave a lot of route options. I did have a general feeling that I should go south, in this instance and that really only leaves two options, the back road, or the motorway. The back road is a lot prettier!

I made the choice to take the back road but it was not, as I said, at the forefront of my mind, as I was doing other things at the time, like finding my keys, my phone, my wallet and these things occupied the forefront, while the decision about which route to take was more background.

So the route was chosen more of less in the background, but not subconsciously. Much the same process happened on the way there, and at each junction or turning point, I didn’t have to consider at the front of my mind which direction I should drive. I just did it. Some part of my mind knew that to get to our destination I had to turn right, or go straight on or whatever.

This is good because the front of my mind was doing the driving, keeping the car on line, signalling, accelerating or braking, keeping us safe on the road. Except that it wasn’t right at the front mind, since I was also talking to my wife about various things. Christmas things from memory.

I’ve been driving for many years and I’m confident that if needed the driving part of my mind can instantly oust the things currently in my mind should the unexpected happen. Many year ago, when I used to smoke, I was driving with a friend and an emergency happened. When it was over I realised that I was no longer holding my cigarette. Meantime my friend was scrabbling between his legs where my cigarette had ended up when the driving part of my mind grabbed precedence and the cigarette holding part was temporarily ousted.

The route planning part of my mind would not suddenly get control like that, fortunately. That would be highly dangerous. I could if I had wanted have brought the route planning part of my mind to the front, but it wouldn’t say much except “turn left at the next junction”.

I have on occasion made a navigating mistake. I’m going to A and the route to B is the same in part. Suddenly I realise that I have missed a junction and will have to backtrack. It seems that the route finding part of my mind spends much of the time dozing and checks in only infrequently, sometimes missing the turning point or ritually following a more usual route.

It also seems that the information it keeps is like an instruction to take an action at each decision point rather than the whole route from home to destination as well as a general direction, less well specified. GPS guidance systems seem to work this way too in that they instruct you to take an action at each junction without setting out the whole route each time.

The model of the mind that I’ve used above, of various parts of the mind at various levels of “forefrontness” or consciousness is nothing new. The need to make a part of the mind the one at the top of the conscious levels, suddenly as a result of a danger, or selectively by choice, as in route following reminds me of the way that computer programs

Computers have several methods for navigating through programs and reacting to things that happen when they are running. One big part is called “handling errors”. Dividing by zero is an error and if the computer reaches a point where it has to divide by zero something needs to be done. The program can report the error and gracefully stop, or it can take some action to fix the error and then carry on.

Computers handle error by means of “interrupts”. Whether the errors is software (eg divide by zero) or caused by hardware connected to it (eg input/output errors) the computer stops what it is doing and runs a bit of program that handle the errors by sending a message or fixing things up. The bits of program that were running are suspended and after the error is handled the bits that were running may be given back control.

The mind seems to work in a similar way. When an emergency arises the current part of the mind that is at the forefront gets suspended and the emergency is handled by another part of the mind. A pedestrian steps into the road and you react by standing on the brakes “before you know it” as the saying goes. As soon as the emergency is over, the conscious mind takes over again.

You do indeed react “before you know it”, one might say instinctively. But humans have not been driving cars for much more than one hundred years, so it appears that the reaction is not instinctive in itself, but is an instinctive reaction to a danger that has been learned. We seem to have this fast reaction to events which is instinctively based but can be applied to learned situations, which is much more flexible than hard-wired instincts would be.

So, pondering on how I get from A to B has led me to conjecture that there are parts of the mind which are forefront in our minds and other parts which are not directly in the forefront but which can be brought to the forefront in an instant, when an event happens. It is evident that these parts are only partially backgrounded as the mind as a whole has some aware of the location at the time, but they do act semi-autonomously, that is until the pedestrian steps out onto the roadway.

Evidently there are parts of the mind that are less foregrounded and more backgrounded. When the part of the mind that is concerned with driving wants to signal or change gear, another part of the mind which controls the arms and legs wakes up and make the limbs move as needed.

I’ve spoken above as if all these different levels are discrete states, but I think it more likely that is a continuum from the foreground of the mind to the background or a least the series of levels of consciousness are close enough togerther to appear so.  The mind is a complex and wonderful thing.

[Comment: After finishing this post I went looking for other discussions of the same topic. I first found this Wikipedia article which has the issues mentioned in the article’s header. Interestingly the implication in the article is that there is a single level of consciousness at any one time. This I do not agree with. Another article I found was a little better, I feel, but only because it acknowledges that several levels may be active at the same time, but divides them into three levels with well defined scopes. I feel that it is a lot more complex than that, with all sorts of sections of the mind at all sorts of levels being active at the same time. Neither article deals with the issue of one section of the mind apparently seizing the highest level when an external event triggers it.]
