U23 Pursuit Recap: Women

Just a quick follow up to my earlier post examining some of the North American men in today’s U23 pursuit, this time for the women. I’ll just focus on three ladies: Sadie Bjornsen, Caitlin Patterson and Alysson Marshall. Here’s the graph for Bjornsen: Today’s race (blue) seems neither much better nor much worse than she’s […]

U23 Pursuit Recap: Men

As before, with the U23 racers we typically have more data to work with, since these folks have generally been around longer and so are likely to have raced against each other more often. We’ll continue using the percent back difference plots, that examine how a particular skier has fared against each of their competitors […]

Animated WC Points Tracker

A little fun using the Google Charts API, R and my WC points spreadsheet. Both of these motion charts require Flash. It shows the progression of WC points for the top 30 athletes or so throughout this season. Distance points are on the x axis and sprint point are on the y axis. This does […]

I’ve said it enough that I should probably provide some evidence: […]

U23s: 10/15km Freestyle

Today’s U23 races in Estonia resulted in victories for some talented young skiers, Russia’s Evgeniy Belov and Finland’s Krista Lahteenmaki. In both cases their wins were fairly convincing, with Belov distancing himself from second place by 16 seconds and Lahteemaki crushed the women’s field by a full minute. One of the difficulties in gauging performance […]
