US Development – Men

Continuing on from earlier this week, we’ll look at some US men in the “development pipeline”, although I use that term pretty loosely. Basically I just mean some of the top US men who aren’t necessarily obviously going to be skiing WC full time or something. (Click for full versions.)

Miles Havlick and Erik Bjornsen are interesting cases, similar to Joanne Reid as I mentioned earlier. His FIS point trend is promising, but he’s mostly been on the “easy” part of the curve up until now.

US Development – Women

I’m going to run two quick posts looking in on some of the US’s top men and women in the development pipeline (all that really means is that I’ve mostly, but not completely, excluded some “obvious” US Ski Team members).

We can check in on how these folks are doing by using my cohort plots, which compare their FIS points vs. age to the FIS points vs age earned by skiers who went on to finish in the top ten in a WC/OWG/WSC event. That’s a fairly low bar of just one top ten finish, ever, since I want to emphasize that I’m trying to be as generous as possible here. The following two plots summarize a few of the top US women (click for full versions):

The blue lines are the median FIS points for each athlete, and the gray shaded regions show the equivalent range of values at that age across all athletes who went on to achieve a top ten result in a WC/WSC/OWG event. I think this mostly speaks for itself, but I wanted to draw attention to Joanne Reid. One aspect of plots like these is that it’s much easier to look like you’re “on the path” prior to age 22 or so, simply because the FIS point curve bends so steeply up when you go back that young. She’s one to watch, but the next two years, where the FIS point curve start to flatten out, will be the first real test to see if she can keep pace.

Patience Is Not A Virtue

I’m going to do something stupid in this post. I’m going to disagree with someone who has likely forgotten more about the sport of XC skiing than I will ever know.

It’s World Championship team selection time, and in North America that pretty reliably means some drama from the peanut gallery, represented here by the commenters over at FasterSkier. Lots of people like to poke fun at the folks commenting there (which I have done myself, from time to time), but  occasionally people weigh in whose opinions I find interesting. Here is the comment that got me to complaining last week on Twitter:

[I]t’s interesting that it takes the Canadian Team selection to get into some very good and serious discussion about what the US has been doing in this regard for the past several years.

I do not sponsor or favor any particular athletes. I do not know many of them, or much about their capabilities, not having seen them ski or race a whole lot. All I do is study the WC results and the ages of the skiers–emphasis on “ages.” Then I tell some of the younger skiers I DO know that they should not be impatient, that they should not expect significant results on the WC circuit until they are older. You should ask why.

A simple study of WC results shows that the majority of the top 30 finishers are between the ages of 25 and 30. About as many are older than 30 as there are that are younger than 25, but these two groups make up only about 1/3 of the total. (Please note that the successful women mature a bit earlier and their ages–for success– are a bit younger than the men’s.)

I have seen virtually no examples where our skiers mature earlier than their counterparts from Europe, Scandinavia, Russia, and so on. (Exception: Bill Koch. Northug is a Norwegian example.) Therefore, it doesn’t make sense to me to expect our younger skiers to perform really well. It’s going to take time. Now what the coaches do to optimize the time needed to reach maturity is their job. It does seem many of the older skiers have been abandoned in the past years in favor of younger stalwarts. It’s also noteworthy that our older skiers–Randall, Newell, Freeman, Brooks and even Stephen (26?)–are getting the best US results.

This was posted by someone called caldxski, so we can’t be 100% sure of who it was, but it seems like a fair bet that it was someone living in Vermont who’s last name begins with “Cald”. Hence the first two sentences of this post.

In any case, I have two issues with this. The first is that the bit about how many top 30 World Cup skiers there are between the ages of 25-30 is just incorrect. The claim appears to be that a “majority” of top 30 WC skiers are 25-30 years old, and the remainder (under 25,30+) account for about a third of the total. That suggests that the other 2/3 are the folks between the ages of 25-30. My arithmetic tells me that we should be seeing around 20 skiers in the top 30 between 25-30 years old, and the remaining 10 should be split evenly between those under 25 and over 30.

It just so happens that I can count up how many such people there were of various ages in the top 30. All of them.

This is the average number of people aged 25-30 finishing in the top 30 of World Cup, Olympic and World Championship races by season, for the past decade or so:

age25-30a

These lines are not hovering around 20. They are hovering just below half, between 10-15. The men’s numbers have risen very slightly over the past 2-3 seasons.

What about the younger skiers? Based on the comment above, we might have expected only around 5 people under the age of 25 in a given WC race. Here’s the reality:

age24a

Now, there’s absolutely no reason to expect someone to accurately estimate these things just by looking at results sheets, even if you’re looking carefully and paying attention. So there’s no shame in being wrong about this; the whole reason I started this website was because of how difficult it is to accurately get a sense for these things simply based on your gut. But this mistake leads directly into the second issue I have:

…it doesn’t make sense to me to expect our younger skiers to perform really well.

With all due respect, this seems like madness to me. First, we’ve demonstrated that the premise is incorrect: although many certainly are, the majority of top 30 skiers are not, in fact, between 25-30. But even if the premise were true, it does not follow that it is “OK” to be slow in your early 20’s. I’ve written numerous posts on this, but I’ll say it all again:

A strong majority of the very best skiers in the world have demonstrated an ability to ski at the highest level well before they turned 25. And when I say “demonstrated” I’m talking scoring World Cup points (or better), regularly.

Here’s what I mean:

perf_age

 

I took all skiers who’ve notched even a single top 10 result at the WC level in the past 5 years, and then grabbed the results for their entire careers. This shows the proportion of WC starts by these skiers that resulted in a podium, a top 10 or a top 30 result, by age.

Let’s focus on the blue line, corresponding to scoring WC points, and just the men’s distance panel: prior to the age of 25, these skiers were landing in the points at least 1 race in 4, and that quickly rises to 1 in 2 before they turn 25. The other three panels paint an even starker picture of the performance level of top skiers at younger ages. How can we reconcile this with the implied message that we shouldn’t expect our young skiers to be fast?

The answer, I think, is that we can’t.

It is true that we shouldn’t expect a 23 year old to race as well as they could with another 5 years of training under their belt. But we should expect them to race as well as the best 23 year olds in the world. And guess what? The best 23 year olds in the world are quite capable of scoring WC points, or better.

 

First WC vs Performance

Continuing with the athlete development theme recently, here’s a graph showing the age at which a skier races in their first WC versus their overall median WC result:

For fairly obvious reasons, you have read this fairly carefully, particularly at the more extreme ages. I wouldn’t pay much attention to either panel past the age of 30, simply due to sample size.

What I find interesting about this is that for the men, at least, it reinforces the idea that 25 is really the maximum age at which you want to be cutting your teeth on the WC circuit. The relationship for the women is more stable, indicating an interesting contrast between the genders. It seems that it’s at least more likely for women to start late and not perform (on average, across all skiers) significantly worse than folks who started on the WC at a fairly young age. I want to emphasize that that’s a relative conclusion, i.e. that we’re simply saying that the women are more likely to see that happen than the men, rather than saying the women are generally likely to start late and perform really well.

Domestic Podium Development

I got a request for some similar graphs from my podium development posts, but focused more on the domestic scene. So, for example, we had this graph:

This showed the age at which future WC podium finishers achieved a particular milestone. So let’s turn to just US and Canadian skiers who have simply participated in a WC over roughly the same time span and make a similar graph, with a slightly expanded set of milestones:

Sprint and distance have all been lumped together here. The only thing I’m going to point out with this is the rather dramatic age difference for the skier’s first WC start. Note how for the international podium winners, it is virtually unheard of for them to have cut their teeth on the WC after the age of 25. Now look at the domestic graph; many more of our WC athletes are getting their first taste of WC action at a very late age.

It’s important, as always, not to confuse cause and effect here. Dumping skiers into a WC at the age of 21 won’t magically turn them into podium material. (But it might not hurt…) A more plausible explanation might be that other countries are doing a systematically better job at developing athletes faster, such that they are at the right stage of their development for a first WC start at a significantly earlier age.

Development Patterns In Detail

As promised from last time, I’m going to show you the un-aggregated data from Tuesday’s plots. This means we’re going to have some big graphs, bigger than I typically think is useful, but no matter.

I’ve plotted FIS points versus age for each of the male and female skiers with a podium result in a major international competition, and indicated the age at which each skier attained their first WC start, their first points and their first podium. If you only see two (or fewer) vertical lines, that means that some of those events happened at basically the same age. (Keep in mind that my age data is only at the resolution of a whole year.)
