San Francisco ½ marathon [1:26:32 – 15/7533]

Just completed the 2016 San Francisco ½ marathon. And this despite Air France’s best efforts to keep me out of it (and thanks to my son!), a long flight and hardly any sleep before the 5:30am start. This is the most brutal, unforgiving, relentless ½ I ever ran, with a significant positive differential of more than 700 feet (215 meters) and according to other runners with tracking devices possibly 0.3 miles extra (close to 500 meters). And fierce winds on the Golden Gate Bridge, both ways! So I am utterly flabbergasted by the outcome, which sees me arriving 15th altogether and first in the over 50 group [and third French!]… race_2167_photo_39804811Even though I presume the training for Monte Rosa, the (unsuccessful) attempt at Monte Rosa, and the additional bike rides the previous month helped, although I did very little speed sessions. The race got hard the moment we started climbing, first a little hill near Fort Mason, then the slope to the bridge that truly slowed me down. Crossing the Golden Gate Bridge both ways was exhilarating, although I could not see one pile from the previous one, being in a cloud the whole time and Sun being not up yet. And although this section of the race was the most exposed, with no runner around to run in packs. Thankfully, there was one big downhill run around the 11th mile (that I passed in 1:11:11!) which helped me gaining back some time if no position, and facing the last climb, which seemed to last till the finish line in the Golden Gate Park… My overall time of 1:26:32 is surprising in itself if I account for the elevation: by Naismith’s rule, that would brings the time on a flat terrain under 1:20, a feat I only achieved once. And many other things are just weird in this race, from the 7500 runners I never saw, many of which finished over 4 hours, to the number of young winners (the third male runner is 17, the first female runner 20, a 14 year old came 22nd and even weirder the second female in the 5k is 8 year old!). And to the fact my ranking changed several times from 18th to 16th, 15th, 17th, and eventually 15th again.  [Congratulations to the organisers, by the way! The whole race was brilliantly organised with all kinds of amenities I had never seen before. And thanks to the supportive Erythrean taxi who took me from the airport and offered me a free ride back if I ended up in the top ten! It sounded like a joke at the time….]

Bayes by the Bay

No, no, this is not an announcement for a meeting on an Australian beach (which is Bayes on the Beach, taking place next November (6-8) on the Sunshine Coast and is organised by Kerrie Mengersen’s BRAG, at QUT, that I just left! With Robert Wolpert as the international keynote speaker and Matt Wand as the Australian keynote speaker.) Bayes by the Bay is “a pedagogical workshop on Bayesian methods in Science” organised by the Institute of Mathematical Sciences, based in the CIT campus in Chennai. It is taking place on January 4-8, 2013, in Pondichéry. (To use the French spelling of this former comptoir of French India…) Just prior to the ISBA Varanasi meeting on Bayesian Statistics.

Great: the webpage for the workshop uses the attached picture of Pierre-Simon (de) Laplace, rather than the unlikely picture of Thomas Bayes found all over the place (incl. this blog!). This was also the case in Christensen et al.’s Bayesian ideas and data analysis. So maybe there is a trend there. I also like the name “Bayes by the Bay“, as it reminds me of a kid song we used to sing to/with our kids when they were young, “down by the bay“, after a summer vacation with Anne and George Casella…

Coincidentally, my re-read of Laplace’s Théorie Analytique des Probabilitiés just appeared (in English) in the Boletim ISBrA, the dynamic Brazilian branch of ISBA.
