"Run... you fools..." (aka les 20 km de lausanne)

Running, on a rainy day...

In an everlasting effort to partake of the local life, to experience the place in which we live, and to enjoy a grand event together, the Lasa team took part in the 20km de Lausanne this saturday, sporting 8 participants to the celebrated running competition. Since we're still scientists and not weathered sportsmen, we elected to run the 10km, which accompanies the participants along the lake shore, then sends them up to the Parc de Milan, down again through the Vallée de la Jeunesse and eventually back to the Vidy park.

The weather was bad, rain and cold worsening by the kilometre, but it could not mar the spirits of the Lasa members and their support teams (wives, girlfriends, friends, sisters) who cheered and motivated the by then soaked and trembling runners in the middle and in their last stretch of the race.

As for the aftermath, the humble author of this here text will spend the day on the couch, dreading the moment in which he will have to get up to fetch the laptop charger, and generally trying to remember that, while not necessarily being able to sense them, he still has 4 articulated limbs…

In any case, to provide some data (we are, after all, a machine learning lab) here are some results on the race itself.

 

The LASA Participants:

  • Guillaume de Chambrier
  • Mohammad Khansari
  • Seungsu Kim
  • Klas Kronander
  • Basilio Noris
  • Guillaume Pihen
  • Nicolas Sommer
  • Ajay Tanwani

Plus some 7000 other people who managed to finish the race..

So let's have a look at the age distribution for all participants to the 10km race

We could speculate about what this graph says about the competitive spirit, or the willingness to take care of one's own body, or health consciousness of men and women, but to be on the safe side, let us just remark the definite shift toward a younger age for female runners, and the curious gap between the peak age (28 for women, 34 for men) and the plateau of participants that are some 10 years older than that...

 

Race Results

Let us start with the overall results for the 7000 something participants to the 10km race, segmented by age.

It is interesting to note that, while it is true that women run a tad slower than men (this can be explained in part by the fact that on average they have shorter legs...), their performance does not seem to suffer from age as much as men's (this tendency is clear as day in the 16-60 years range).

 

Team LASA

And now, since we're here to talk about us after all, let us look at the results, in infographic format, of the LASA participants:

And here are the same results plotted on the same graph above

And to describe these results in terms of numerical achievements:

  • The LASA team's average time was below one hour (58 min 40 sec), thanks in no small parts to Guillaume P and Klas
  • Guillaume P and Klas ran faster than the men's average time of 52 min 4 sec (std: 7 min 37 sec)
  • All LASA members ran in less than 1h 10 minutes
  • All LASA members were within two sigma of the men's average
  • LASA members had an average running speed between 9.0 km/h and 12.6 km/h

And of course, the methodological caveats (latin for "excuses for why we're so bad…") :

  • The dataset contains only people who DECIDED TO PARTICIPATE to the race
  • The results are only for those who FINISHED the race

 

The Verdict

All in all, these results count as AWESOME in my book! So kudos to Guillaume Pihen and Klas Kronander for their outsdanding results, congratulations to all the others for finishing the race so fast and a big hooray to the LASA team and friends for an unexpectedly and deserved good performance!
