La Rochambelle, 15000⁺ women in pink! [38:53, 118th & 8th V2…]

As essentially every year in the past decade, I have run the 10K in Caen for Courants de la Liberté, with 5000⁺ runners, on once again a new route, still completely intra muros in the city of Caen, and mostly flat, with highlights Guillaume’s medieval castle and Men Abbey,  the gothic St. Pierre church,  and a few other churches. It went reasonably well if not great (although I ran the first 5K’s in 19:02) as I ended up at a mediocre position (8th) in my category, which is not surprising with some runners now 9 years younger than I! (The runner next to me is the first V3.) Weather was much better than last year, if still too hot. I however primarily want to congratulate my mom and my mother in-law for walking the 6⁻ km Rochambelle the previous evening  in great cheer despite the rain and the crowd. I could not spot them on the picture above…

 

semi-marathon d’Argentan [1:27:27, 22/356, 2/65]

As a new anniversary of the beginning of this ‘og, here comes and goes my yearly half-marathon in Argentan, Normandy, which was the 33rd edition of the race and my 19th participation there…

“Ah, le fameux Robert de l’INSEE qui vient faire chier chaque année!”

This was not one of my best races, by far, and the [fake] news that this was going to be the last edition did not help. There were fewer runners than in the earlier races, meaning no protection on most of the route from what seemed like a constant headwind, as I ran by myself from the third kilometre. And I was tired from too much training (and not enough sleeping) the past week in Warwick. Or not enough training the previous week in Vienna. Anyway, this was not a great race and the local V2 [Grand Master] runner who greeted me with the above good-natured apostrophe when I passed him on the second km ended up one minute ahead of me. I could have even stopped at mid-race, were it not for a deficient watch operation, that kept me thinking I could keep with my earlier time [3:39 – 3:50 – 3:59 – 3:53 – 4:00 – 4:28 – 4:11 – 4:06 – 4:04 – 4:07 – 4:24 – 4:39 – 4:01 – 4:12 – 4:05 – 4:14 – 4:03 – 4:16 – 4:17 – 3:58 – 0:25] till the finish line when I found a 4mn difference with the official time! Despite the low participation of 356 runners, and with the support of runners from England, the town of Argentan has vowed to keep the race on for next years, calling for volunteers to man the route and the arrival hall. Till next time, then, hopefully!

a trip back in time [and in Rouen]

On Monday, I took part in a celebration of the remarkable career of a former colleague of mine in Rouen, Gérard Grancher, who is retiring after a life-long position as CNRS engineer in the department of maths of the University of Rouen, a job title that tells very little about the numerous facets of his interactions with mathematics, from his handling of all informatics aspects in the laboratory to his support of all colleagues there, including fresh PhD students like me in 1985!, to his direction of the CNRS lab in 2006 and 2007 at a time of deep division and mistrust, to his numerous collaborations on statistical projects with local actors, to his Norman federalism in bringing the maths departments of Caen and Rouen into a regional federation, to an unceasing activism to promote maths in colleges and high schools and science fairs all around Normandy, to his contributions to professional training in statistics for CNRS agents, and much, much more… Which explains why the science auditorium of the University of Rouen was packed with mathematicians and high schools maths teachers and friends! (The poster of the day was made by Gérard’s accomplices in vulgarisation, Élise Janvresse and Thierry Delarue, based on a sample of points randomly drawn from Gérard’s picture, maybe using a determinantal process, and the construction of a travelling salesman path over those points.)

This was a great day with mostly vulgarisation talks (including one about Rasmus’ socks..!) and reminiscences about Gérard’s carreer at Rouen. As I had left the university in 2000 to move to Paris-Dauphine, this was a moving day as well, as I met with old friends I had not seen for ages, including our common PhD advisor, Jean-Pierre Raoult.

This trip back in time was also an opportunity to (re-)visit the beautifully preserved medieval centre of Rouen, with its wooden houses, Norman-style, the numerous churches, including Monet‘s cathedral, the Justice Hall… Last time I strolled those streets, George Casella was visiting!

La Rochambelle, 25000⁺ coureuses! [39:29, 24⁰, 164th & 7th V2…]

As almost every year in the last decade, I have run the 10K in Caen for Courants de la Liberté, with 5000⁺ runners, on a new route completely in the city of Caen, partly downhill..! It did not go well (although I started in 3:44 on the first three k’s) as I ended up at a poor position (8th) in my category, which is not surprising with some runners now 8 years younger than I! (The runner next to me is the second V3.) And a fairly hot weather, especially for a Norman early morning…. Several runners fainted on the race or upon arrival and the faces of most runners showed the strain. But I first and primarily want to congratulate my mom for walking the 6⁻ km the previous evening despite serious health issues in the previous months, as well as my mother in-law who walked with her.
