Split analysis: World Cup Gällivare, Women 10km, 20/11

Posted by Jan Kocbach, 20 Nov 2010@10:55


Marit Bjørgen was fastest at all splits in the season opener in Gällivare today! A very impressive race by Bjørgen, who seems to be in great shape this early in the season. Above you see a screenshot from Splitsbrowser which gives you a graphical overview of how the race developed.

In the above Splitsbrowser-screenshot a flat line on a split means that an athlete is the fastest on a split. The steeper the line goes, the more an athlete looses on that split. Split 1 is at 1.8 km, split 2 at 2.2 km, split 3 at 5.0 km, split 4 at 6.8 km (same position as split 1), split 5 at 7.2 km (same position as split 2) and finish at 10.0 km.

As you can see from the illustration above – and also from the splitsbrowser if you play with it yourself –  nobody was even close to keeping up the speed of Marit Bjørgen. The only one trying was Kristin Størmer Steira who kept the speed of Bjørgen between split 3 and split 4 after being caught by Bjørgen by 30 seconds out in the course. As you can see from the illustration, that period got tough for Steira - resulting in a fall through the results list from a 3rd spot down to a 5th spot.

The following illustration shows how many percent each runner lost to the best split time on each split. Bjørgen of course has a flat curve at the top – being best at all splits. Bjørgen is strongest at the short splits between 1.8 and 2.2 km and between 6.8 and 7.2 km (they seem to be partly downhill and partly uphill from the course profile). At the part between 2.2 and 5 km (and 7.2 and 10 km) she is not that dominant – Skofterud and Kalla being very strong in this part of the course.  Looking at the course profile, you can see that this is the flatter part of the course.

Skofterud versus Steira

Above you see curves comparing the position at each split for Kristin Størmer Steira and Vibeke Skofterud. As you can see, Skofterud got stronger and stronger through the race. Starting at a 10 place at the first split, and finishing with the second best split at the last split.
