A few weeks ago, I contacted my general (and sport) practitioner for a mild issue with hurting toes, as they were indeed hurting and not only during or after my daily runs (!). Since the beginning of lockdown. I thought he would tell me to contact him later and stop running in the meanwhile but instead he told me to come to his office and after a rather cursory glance at said toes started discussing on a rare occurrence of COVID-19 induced frostbite-like toes. He then ordered a blood test which I took the next morn. Right after my (legit and solitary) one hour run. The results of the test were within the “normal” boundaries, except for the D-dimer test which was above the limit and is usually intended for detecting deep venous thrombosis. (As reported on Wikipedia, “a four-fold increase in the D-Dimer protein is a strong indicator of mortality in those suffering from COVID-19.”) This caused my physician to react quickly by prescribing me a cocktail of anticoagulants, corticosteroids and antibiotics. And another test four days later, incl. one for COVID-19. While anticoagulants made sense wrt to the coagulation issues, the corticosteroids were a surprise as they had been earlier pointed out as a potential aggravating cause for younger patients. Including by the French Ministry of Health. I thus asked my daughter for advice, as she had been triaging potential COVID-19 patients in the emergency room for the past month and she was strongly negative about the treatment, both because of the corticosteroids and of the antibiotics. Treatment that was apparently advocated by my practitioner on his own. I thus waited for the second round of blood tests, which returned a lower D-Dimer level and a negative signal for COVID-19. (In the meanwhile, I had spotted a BMJ paper on the possible impact of extended running on the D-Dimer levels and hence waited till the mid-afternoon to take the test!) While this ended up as a non-story, only made more exciting by the lack of competitive events during the lockdown!, I find it interesting that my doctor, who was most reasonably worried about the rising number of COVID-19 among his patients, leaned towards a viral conclusion with little data, as my month-old return to intensive (daily) running was a more likely explanation for sore toes…

free fall [fake]

As I was looking for the location of a picture serving as a background image for Windows 10 log-in page, I came across several versions of the above, supposedly showing a climber failing to grab another climber’s hand and as a result falling. Or “falling” as the image is obviously doctored, most likely by removing the ropes securing both climbers. This is fairly ridiculous, from the top climber hanging by his hand to the bottom one carrying quickdraws on his harness, as in the worst climbing movies… Still, I wish the location of the shot was provided on the website. (As an insider joke, I had a fall when running that was definitely not fake during the Xmas vacations, scraping a fair amount of skin on the gritty sidewalk, but with no apparent lasting damage, although I am barred from running by a tendinitis which started in Warwick last month..!)

should I run less?!

Run_ABCA study [re]published three days ago in both The New York Times and the BBC The Guardian reproduced the conclusion of an article in the Journal of the American College of Cardiology that strenuous and long-distance jogging (or more appropriately running) could have a negative impact on longevity! And that the best pace is around 8km/h, just above a brisk walk! Quite depressing… However, this was quickly followed by other articles, including this one in The New York Times, pointing out the lack of statistical validation in the study and the ridiculously small number of runners in the study. I am already feeling  better (and ready for my long run tomorrow morning!), but appalled all the same by the lack of standards of journals publishing statistically void studies. I know, nothing new there…

Argentan half-marathon [1 23’38”-31/583-V2:1/111]

Early readers of the ‘Og might remember that the very first entry was about my 2008 half-marathon in Argentan! I was not particularly happy about the outcome, due to a recurrent tendinitis. In the subsequent races, I was injured for two years in a row and last year saw a combination of very hot weather and reduced training thanks to two broken ribs. Last Saturday, I ran the Argentan half-marathon for the 16th time (including the year I ran it by myself as it had been cancelled!). Despite a bike fall three weeks earlier, I managed to get my training schedule completed (partly thanks to the opportunities offered by the trip to Bristol) and to follow a slightly stricter diet than usual. Whatever the reasons, this proved to be successful, in continuity with three earlier podiums this year!

The weather happened to be much better than last year, meaning it was cold, only mildly raining (this is Normandy after all!), and with a moderate wind (always the issue with this race). As shown by the above picture (kindly provided by Normandie Course à pied), I stuck with a group of runners who had mentioned a goal of 1 hour 25 minutes (at the start) for the first half of the race and, feeling in great shape by then, increased slightly the pace in the long uphill track in the Gouffern forest, left the group (which prompted some grumbling for unfairness by runner 660, believe it or not!), passed three more runners, and finished in 1 hour 23 minutes and 37 seconds, which is far from my best times in Argentan (1 20′ 34″) but nothing to complain about. I ended 31st in the race (out of 800 plus runners) and first in the V2 category, which led me on the podium for the first time since I started this race in 1995. (As Peter Green got me into running that race, I hope he will not mind if I dedicate this [very minor] victory to him and his wife Liz [who also won Argentan a few years ago].) As I ended up 34th last year versus 31st this year, I do realise that I benefited from the “Law of Small Numbers“: the presence/absence of just a few runners has a determining impact on the outcome and this year, the three V2 runners that were in front of me last year did not show up.

Here is an attempt at representing in R the split times with a background image (and the part in the forest), but it does not look that great (and I could not remember how to modify the axes and label colors with a simple option…)

Not back from Argentan

The half-marathon in Argentan took place yesterday and, out of sheer masochism, I looked at the results of the first runners. This is more than frustrating as, even with my poor time from last year, I would have made it in the first ten V1’s (1:24;36) and before the first V2 (1:22:40)… But I have another month of complete rest from running before checking with the doctor whether or not I can run again.
