do cartoons help?

I received a (mass) email from Taylor & Francis about creating a few cartoons related to recent papers… As in the example above about the foot strike of Kilian Jornet. With a typo on Font-Romeu. Apart from the authors themselves, and maybe some close relatives!, I have trouble seeing the point of this offer, as cartoons are unlikely to attract academic readers interested in the contents of the paper.

graphics for the New York City marathon

Central Park, New York, Sep. 25, 2011As the first runners are starting the race in Staten Island, here are six graphics published in the NYT about the NYC marathon, pointed out to me by my friend Darren. The first one is a great moving histogram that I cannot reproduce here, following the four batches of runners. And the unbearably slow last runner! The second graph is an almost linear increase in the number of women running the race (which, by extrapolation, means that the NYC marathon will be an all-female race by 2068!). The third graph is a square version of a pie chart, which shows that the second largest contingent after the US runners is made of French runners (7%), way above Canadian runners (2.7%). The fifth graph shows spikes in the age repartition of the runners, at 30, 40, 50, and 60: since it is unlikely to be a reporting bias, unless id’s are not controlled when registering, which would be strange given the awards are distributed by five year block age groups, this may be due to people making a big case of changing decade by running the marathon or by runners who take advantage a new age group to aim for the podium. The latest explanation is very unlikely as it would only apply to elite runners and as it should also induce a spike at 35, 45, etc. (Incidentally, I checked the winner’s time in my category, 55-60, and last year a Frenchman won in 2:48:19, which means I would have to run at about the speed of my latest half-marathon to achieve this speed…) The last graph is also quite interesting as it follows the winning times for male and female runners against the current world record across years, showing that the route is not the most appropriate to break the record, in contrast with Berlin where several records got broken.

Trip to Louvain (and back)

Rue des Wallons, during the 24 heures de vélo, Louvain-la-Neuve, Oct. 21, 2015Apart from the minor initial inconvenience that I missed my train to Brussels thanks to the SNCF train company dysfunctional automata [but managed to switch to one half-an-hour later], my Belgian trip to Louvain-la-Neuve was quite enjoyable! I met with several local faculty [UCL] members I had not seen for several years, I gave my talk for the World Statistics Day in front of a large audience, maybe not the most appropriate talk for that day since it was somewhat skeptical about the nature of statistical tests, I got sharp questions, comments, and suggestions on the mixture approach to testing [incl. a challenging one about the Bernoulli B(p) case], I had a superb and animated and friendly dinner in a local restaurant—where everyone kindly spoke French although I was the only native French speaker—, I met the next morning with two PhD students from KU Leuven (the “other” part of the former Leuven university, albeit in the Flemmish side of the border) about functional ABC and generalised Jeffreys priors, I had a few more interesting discussions, and I managed to grab a few bags of Belgian waffles in Brussels before heading home! (In case you wonder from the above pixture, the crowds in the pedestrian streets of Louvain-la-Neuve were not connected to my visit!, but to a student festival centred at beer a 24 hour bike relay that attracted around 50,000 students, for less than a hundred bikes!)

Argentan half-marathon [1 24′ 46″ – 22/496 – V2: 2/116 – 17°C]

ADSC_0135A fairly good race in Argentan, despite (relatively) hot weather that saw the winning time increase by two minutes and a half. (Last year’s winner actually lost 3 and half minutes on the same track). Gaining 18 seconds over my time from last year was thus a significant achievement. This was my 17th—or 18th including one I ran on my own as it had been cancelled—Argentan half-marathon. The first half [of the half] was a bit unpleasant under the relentless sun, and each wee slope made me miss my 3:52 kilometre goal. But very few runners passed me for good after the 5th kilometre and reaching the forest part was a blessing, providing shade and cool. A single runner passed me there, although I had not slowed down, and I did not realise it was another runner in my V2 category as I could have tried to keep up. The last kilometres were indeed much smoother than in previous, thanks to a change in my training where I increased the number of long distance trainings. And presumable thanks to the previous week abroad when I trained twice a day. Anyway, I was still surprised to end up as the second V2, 15 seconds from both the first and third V2 runners. Which got me a nice Timex watch as a reward! And a pretty ugly cup… [Thanks again and again to the photographs of Normandiecourseapied for their free pictures!]


Argentan, 30th and 17th and 7th edition(s)

Posted in Running, Travel with tags , , , , , , on October 2, 2015 by xi'an

When I started the ‘Og, in 2008, I was about to run the 23rd edition of the Argentan half-marathon… Seven years later, I am once again getting ready for the race, after a rather good training season, between the mountains of the North Cascade and the track of Malakoff. with the last week in England, Holland, and Canada having seen close to two trainings a day. (Borderline stress injury, maybe!) Weather does not look too bad this year, so we’ll see tomorrow how I fare against myself (and the other V2 runners, incidentally!).
