World Cup Long Spain: Quick GPS analysis

Posted by Jan Kocbach, 05 Apr 2014@19:20

Through a cooperation between World of O and TracTrac, it is now possible to open TracTrac orienteering events in 2DRerun for analysis when the TracTrac events are in replay mode. Below follows a very quick GPS-analysis of the World Cup long distance in Spain this Saturday.

Note that the GPS-measured lengths are quite far off in some cases as the GPS reception seems to not have been ideal for all runners. The men’s analysis illustrations are based on actual official split times whereas the women’s analysis illustrations are based on GPS split times (with some inaccuracies. C lick on each illustration to see it bigger.

Men leg 1


Going slightly right like Kratov and Rollier do is the fastest choice here – not however that there are many “micro” route choices on the way, and the execution of the leg is just as important as choosing the correct variant. Rollier looses nearly half a minute to Lundanes on the first 400 meters of the leg – thus Rollier’s variant could have been even faster with a better start. Lundanes and Sild loose around half a minute by running direct.

Going far around to the right and taking the control from the road was fastest in the women’s course – the women having a similar leg. However, this option is a bit too long with the control placement in the men’s race – also the men are usually stronger when running direct.

Men Lundanes versus Rollier


Above you see an autOanalysis of the races of Lundanes and Rollier. Rollier has a bad start and looses nearly half a minute on the first part of the first leg – but then executes the rest of the first leg very well.  Rollier’s speed is very high on the first half of the course – loosing some time on “micro” route choices along the way (e.g. to 4 and 11) and also has a half minute mistake on number 7.

Lundanes does a stable race, seemingly with a big lower speed than Rollier. The main time losses of Lundanes is one route choice loss (control 1) and the mistake at control 24 (according to Lundanes due to loosing focus after control 22 being removed).

Women leg 1


(Note: GPS-times only here). On the first leg for women going all the way around to the right and taking the control from behind is the fastest (Eliasson, actual time 19:08). Helena Jansson has probably run approximately the same route (some of the GPS-track is missing), and is even a few seconds faster than Eliasson.  Alexandersson looses half a minute (time 19:36 according to official split times) while Mironova runs 19:25 with a route a bit to the left of Alexandersson’s.

The women going left or direct loose a lot of time here – this might also be partly due to the fact that none of the top-runners choose these alternatives.

Women leg 5


Alexandersson looses more than a minute by going direct – using the path system to the right is clearly fastest here. Especially if you run as fast as Eliasson.

Women Alexandersson versus Eliasson


Eliasson runs faster than Alexandersson – and also has a better time on the two long legs. However, mistakes on several controls costs too much for Eliasson – only her high running speed saves her a place on the podium, nearly 5 minutes behind Alexandersson.

WinSplits Pro for Iphone: Quick Review

Posted by Jan Kocbach, 01 Apr 2014@5:00


One of my favourite computer programs for race analysis is WinSplits Pro – a orienteering split time analysis program released back in 2007 by Mats Troeng, but it still does its job very well. Yesterday the iPhone version of the program, WinSplits Pro for iPhone, was released.

The programmer behind WinSplits Pro for iPhone is Ludvig Eriksson – and not Mats Troeng. Troeng does however support the development and has endorsed the use of the WinSplits name for the iPhone App.

Basic version and Pro version

As for the Windows version, there is a basic free version available with a reduced feature set along with the paid Pro version (the Pro version costs NOK 22,- which is about 3 Euro).

No graphical functionality

Although WinSplits for iPhone is very responsive and easy to use, it has (in its current version) a very limited functionality compared to its big brother – the Windows version:

  • Basically all you get is the possibility to easily download  and see the split times from all events which are available in WinSplits (including storing them offline on your phone). If you buy the Pro version, you can see mistake free times (including adjusting the error threshold) and choose which runners you want to compare the splits to.
  • There is no graphical functionality, no performance index, no hang index etc.

The following are the advantages with the Pro version in the current release:

  • The basic version lets you view only events from the last week – the Pro version lets you search in all events in the WinSplits database
  • See times without mistakes and adjust error threshold + choose which runners to compare
In use: Responsive but limited

The app works as expected, but all you can currently do is look at split times – including mistake free times for each split. Unfortunately one can only study one leg at a time, even with the smallest font size – thus having to always sweep to see the next leg. This makes it difficult to get a good overview. An option to show several splits at a time with a small font size would make it more user friendly. Also,  it would be nice with some sort of graphical overview where you could easily (by color) see on which legs mistakes were done  - and then be able to zoom in on them.


The current version of Winsplits for iPhone does not give a lot more than using the WinSplits website from your phone (this actually gives more data easily accessible in some respects). However, the easy access to split times from new events (especially for orienteers in Norway/Sweden were nearly all events are automatically available in Winsplits online) and the offline capability is enough to recommend downloading the free WinSplits version for iPhone and try it out.

I also hope a future update will contain several of the unique capabilities of WinSplits Pro for Windows. I guess the more people buy the Pro version – the more incentive will the developer have to add features.
