Route to Christmas: Day 24 2010

Posted by Jan Kocbach, 24 Dec 2010@5:00

What would be more fitting than to present a leg from The Course of the Year 2010 – Jukola – at the last day of Route to Christmas 2010? And as a big bonus, you get the winner interview from The Course of the Year 2010 – an interview with the course setter Ari Kattainen.

Interview: Course setter Ari Kattainen – Course of the Year 2010

Q: When did you start planning the courses for Jukola 2010 – and how many hours do you think you spent on it?

Some course examples were made in May 2004 for the Management Team of Jukola when we first time presented our plans to organize Jukola in Kytäjä. In 2004 we submitted an application to organize, Jukola 2009 but it wasn’t successful. We improved the application in 2005 for Jukola 2010, and then we got the rights to do it. Some of the controls and splits appears to be same as in the final courses. Serious planning started in 2008.

For each control, ask yourself if it is really needed.

My work in Kytäjä-Jukola included a lot of other duties in addition to course planning, and I used more than 2000 hours for the project. It sounds like a lot, but when split over seven years it is less than one hour per day.
For a participant, Jukola might be just one out of thirty events per year, but for the organizer it could be 10% of a persons life. Competition Manager Risto Pirinen estimated that the total amount of work for Jukola 2010 was 140 000 hours.

Q: What is the best course you have planned?
I think it is the 7th leg of the Kytäjä-Jukola relay. But we have to remember that this is team work. We had five persons in the core course settlng team. Tapani Partanen and Janne Åberg were in charge of the Venla-relay. Myself and Ossi Autio were planning Jukola courses. We can also count course supervisor Juha Liukkonen as full member of the team. Juha maybe had the best touch for orienteering thinking of top runners.

Q: What is your work flow as a course setter? How do you start?
Work includes a lot of background like:
- selecting map area and competition center
- negotiating land usage permission and nature conservation needs
- setting up target times and styles for the courses

Course planning itself starts with fixed distance sample courses like 7km, 10km, 13km. It gives an idea which areas on the map can be reached.

In big events like Jukola also VIP-control, TV-controls and location drink stations need to be taken into account. Course planning itself starts with fixed distance sample courses like 7km, 10km, 13km. It gives an idea which areas on the map can be reached. Then it continues with selection of K-point location and area for the first controls.

Q: What is your best tip for setting a good course?
For each control, ask yourself if it is really needed.

Q: What was the best course you run in 2010 – and why?
Finnish Championship relay in Kauhajoki. The course required clear tempo changes and the controls were difficult.

Q: What is the worst course you run in 2010?
It takes so much volunteers time to organize orienteering competition that in respect to their work I don’t want name any. But certainly something can be always improved.

Q: What is your biggest success as a runner?
World Champion bronze medal in relay in Sweden 1989 and 6th place in Nordic Championship long distance in 1990 in Denmark.

Q: Thank you to Ari Kattainen for the interview – and congratulations for the great courses at Jukola 2010.

Todays leg number 1

As this is the last day in Route to Christmas 2010 (except for some bonus “leftover” legs the next days), I have included several legs in this edition. The problem with routechoice analysis for a relay is of course that the leg times may be skewed due to people running together – but I still try to do some analysis. We start off with the last leg in the Jukola relay – this is a day leg. The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger):

Webroute

Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.

Then you can take a look at the fastest routes. As you can see Kalevan Rasti is fastest with a direct/northern routechoice. However, looking at the isochrone diagram below, you can see that there is some potential for doing the leg faster by comparing the routes of Kalevan Rasti and TuMe. Looking even further down, the calculated optimal route for the leg is shown – and here you can see that the optimally calculated route is yet another one. Finally the color-route is shown – which I think gives a very good overview of what happened on the leg.

Todays leg number 2

The second leg is from the 3rd leg (the long night) of the Jukola relay. The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg. There is no analysis provided for legs number 2 to 4 in this edition of Route to Christmas – but there should be enough information in the illustrations for you to do the analysis yourself. And why not add the analysis in the comment as well when you are at it…?

Route to Christmas: Day 23 2010

Posted by Jan Kocbach, 23 Dec 2010@5:00

For the second last day in Route to Christmas 2010 we return to Czech Republic. The leg is from SAXBO 2010 in stony terrain in Czech Republic with quite some hills. Leg number 2 from the H21L course is chosen. The event was organized on May 1st 2010. Today we return to a Routegadget leg – tomorrow we are back with another one with GPS-data…

Thanks a lot to Jens Leibiger, Nils Schmiedeberg and Wieland Kundisch for drawing their routes on request! The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger). The leg offers several options – you have to take into account both runnability, paths and contours…

Webroute

Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.

Then you can take a look at how the runners who have drawn their route choice solved this leg. As you can see, Martin Janata was the fastest on this leg of the ones drawing their route – choosing the southernmost variant – following the paths as much as possible. This southern route has the best entrance to the control – and avoids most of the green. If you run this event – please add a comment below to let the other readers know about the best solution.

Route to Christmas: Day 22 2010

Posted by Jan Kocbach, 22 Dec 2010@5:00

Todays leg in Route to Christmas is from the World Championships middle distance final in Trondheim, Norway. This course has got a lot of negative remarks in the orienteering community, but it still contains some interesting legs. One of these legs is leg number 7 in the mens class, which is discussed in a lot of detail in todays edition of Route to Christmas.

This was actually one of the legs which had significant influence on the overall results in this years WOC middle distance, Carl Waaler Kaas taking some time from the other medal contenders. The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger):

Webroute

Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.

Then we start analyzing the GPS data from the leg. All runners in the WOC final wore a GPS, and therefore there is quite a lot of data to analyze here. First we compare the best runners on each of the distinct routes run on this leg. Note that the times given are off by up to 3-4 seconds compared to the official splits due to the inaccuracy in the GPS data and start/stop point.

To get information about where on the leg these runners have lost/won time, we plot isochrones by plotting a dot at the points where the runners have used 20 seconds, 40 seconds, 60 seconds and so on – and connect these with a line. Thus it is now possible to see how Weltzien earns most of his advantage in the first half of the leg – and Gueorgiou looses time at the first part of the leg.

To get more of a feeling about how the field in the WOC middle final spread out on the different alternative routes – and the distribution of fast times on each alternative – we plot all routes on the same map with red color for slow overall time for the leg and green color for fast overall time for the leg. You can here see that most of runners who run fast times choose one of the left variants. There is only one fast runner on the direct alternative, and that is Carl Waaler Kaas. Thus based on this a left variant should be the optimum on this leg.
map20101222000600_colorroute_s

Next we divide the leg in a large grid, and find the minimum pace run by any runner on each cell of the grid. Fast areas are visualized with a green color – slow areas with a red color. There are several interesting observations to be made from this pace distribution illustration. For example, for the first part of the leg the runnability seems to be a lot better just below the hill than on the hill-top (the spot where we earlier saw that Gueorgiou lost time). Also, we see how the path going up the hill on the eastern route choice is slow. Note that the pace distribution here is probably influenced by the fact that fewer runners took the eastern alternative – if more (top placed) runners would have chosen the eastern option the pace might have been higher there.
map20101222000600_pace_l_s

Based on this pace distribution map, it is possible to set up an illustration showing the calculated optimal route (black in the illustration below). It is also possible to identify all points which you can reach in a certain time from the start control. In the illustration below, all points which can be reached at the same time have the same color. Thus it is possible to get an overview over the possibilities for the leg. In particular, it is possible to see where control number 7 should have been positioned in order for the eastern route alternative to be faster (based on the speed data available, which is probably not 100% correct due to the distribution of runners). When studying the illustration, it is clear that the control should be placed in the middle of the blue in the area where the color changes from green to blue to green some 50 meters to the east of control number 7.
map20101222000600_optimal_l

To make the above discussion a bit clearer, the control has been moved to 4 different position, and the optimal route has been calculated for each position. As you can see, the optimal route changes for the different control positions – the eastern control position giving the eastern routechoice as the optimum (note again that the control could probably have been placed a bit more to the west).

The ‘Route to Christmas’ series at World of O was very popular the last years – and I’ve therefore decided to continue the series this Christmas as well. If you have got any good legs in RouteGadget from 2010-competitions – or old forgotten ones which are still interesting – please email me the link at Jan@Kocbach.net, and I’ll include it in Route to Christmas if it looks good. Route to Christmas will not be interesting if YOU don’t contribute.

There will be no analysis about the best routechoice for each leg – you can provide that yourself in the comments or in the Webroute. Not all legs are taken for the interesting routechoice alternatives – some are also taken because the map is interesting – or because it is not straightforward to see what to do on a certain leg. Any comments are welcome – especially if you ran the event chosen for todays leg!

Route to Christmas: Day 21 2010

Posted by Jan Kocbach, 21 Dec 2010@5:00

Todays leg in Route to Christmas is from the first competition in the Nordic Tour in Finland. The leg is not as long as the legs of the last days – it is rather chosen because this is the event I have found with the most GPS units applied [77(!) GPS units just in the mens class] – and therefore this is a very interesting event for some analysis using the GPS data.

The leg is as usually first provided without routes – you may take a look at it and think about how you would attack this leg (if the image is too small, you may click on it to get it larger):

Webroute

Next you can draw your own route using the ‘Webroute’ below. Think through how you would attack this leg, and draw the route you would have made. Some comments about why you would choose a certain route are always nice for the other readers.

Then you can take a look at the best splits for this leg based on the GPS data (I could not find the splits anywhere online – they might be off by some seconds – hopefully not so much as to change the conclusions:). As you can see Valentin Novikov is fastest on the leg on a direct/left route – some seconds faster than the right and left variants.

When we start looking in more detail at the GPS data, it starts to get more interesting. First a density map which shows how many runners choose each route. Red color means that more runners choose a particular route. As you can see, there are three distinctive routes which are chosen by a majority of the runners.

Next we take a look at the pace distribution, i.e. how fast the fastest runners have been on different parts of the leg. Here green is fast and red is slow.
map20101221025600_runandopt

Based on this pace distribution, we can now (as described in the Route to Christmas of yesterday) calculate the time it takes to run to any point on which runners have been on this leg. This is visualized in the below illustration where all points with the same color take the same time to reach. Here one can clearly see how the left/direct variant is significantly faster than the right variant, i.e. the green color is much closer to the control when following the left route than the right route. You can also observe that the direct route actually has potential for being faster than the right variant. The optimal route is again drawn in solid black – no surprises there – it is very similar to the route of Valentin Novikov, except he should have cut through the green and over to the path a bit earlier after around one fourth of the leg.
map20101221025600_optimal_l_s

Finally, an iso-time plot, i.e. an illustration which connects the positions at which runners have used equal time from the start of the leg. This is another way to visualize how Novikov reaches the control ahead of Østerbø.

map20101221025600_dots.jpg

So I guess that in today’s Route to Christmas we can be fairly certain that the direct/left variant of Valentin Novikov is really the fastest on the leg – or have you found a better option? I’m sorry that you didn’t get a long, tough leg like I know most of you like today, but I couldn’t let the chance of looking at all this GPS data run away…
