cross-posting this link from my journal because i think it's worth looking at as the world gets hotter, faster, and folks on here are still training outside (me, seifullaah, vag, etc.) or doing a lot of other outdoor work (adarq). wet-bulb temperature as i write this is 28, or at the top of the range that the authors propose for the upper limit of thermoregulation when doing light exercise. and that's just for young, healthy adults, to say nothing of older people, babies and toddlers, people with health conditions, etc. it's 99 degrees (37.2 and the accuweather "real feel" is 118 (48.8).

my fiancee found an article this morning that used my T+DI measurement and suggested that anything over 160 is too dangerous to do hard exercise. this was after cutting off her own run at 13 miles, at about 10 AM, before it got *really* hot.

stay safe out there, everyone.

Evaluating the 35°C wet-bulb temperature adaptability threshold for young, healthy subjects

This study is the first to use empirical physiological observations to examine the well-publicized theoretical 35°C wet-bulb temperature limit for human to extreme environments. We find that uncompensable heat stress in humid environments occurs in young, healthy adults at wet-bulb temperatures significantly lower than 35°C. In addition, uncompensable heat stress occurs at widely different wet-bulb temperatures as a function of ambient vapor pressure.

After getting a headache 2km into my intended 3km test today I got frustrated. My result, 2km in 7:46, translates to a 20:30 5k by pace, which means essentially zero improvement over the last year. I haven't been the most consistent with training but I haven't been a complete slouch, either. Zero improvement would be depressing. So I did a bit of research about running the heat. Turns out, humidity is worse than heat because it impedes sweating. That makes sense. It has been super humid here this summer.

Humidity is measured by % or by dew point. This article - - from Runners Connect showing the dew point effect on running. Forgive the fucked up formatting, hopefully it's legible at least.

Dew Point in °F (°C)                 Performance Adjustment   Easy Running   Hard Running
<55 °F (12°C)                         0%                                   Unaffected           Unaffected
55°F (13°C) to 60 °F (15°C)      1%                                   Unaffected           Slightly difficult
60°F (16°C) to 65 °F (18°C)      2-3%                                Slightly difficult   Difficult
65°F (18°C) to 70°F (21°C)      3-5%                                 Difficult           Very difficult
70°F (21°C) to 75°F (23°C)      5-8%                                 Difficult           Very difficult
75°F (23°C) to 80°F (25°C)      12-15%                             Very difficult   Not recommended
Above 80°F (25°C)                      Just run                         Not recommended  Not recommended

Anyway the dew point here today is 75 degrees, and air temp 90. According to the chart that means easy running should be difficult and hard running very difficult, edging into not recommended. Calculators should always be taken with a grain of salt but it's a bit of a relief to see how much of an impact the dew point is expected to have.

I've said it before and I'll say it again, I can't wait to run in cooler and less humid weather. Only one way to find out how true this all is.

Also, adarq, for the love of god: Get yourself to some autumn races where it's cool and dry. Like go as far north as North Carolina at least, in October or November. I'm tryna see you run 16:20.

800m+ Running and/or Conditioning / fastest known times - ultrarunning

Came across this article in Outside about a rash of "FKTs" in ultra running last year:

For many, it seemed a foregone conclusion that Karel Sabbe would be awarded the male FKTOY for his herculean showing on the AT. The 28-year-old Belgian dentist and relative newcomer to the world of ultra-running did what many people thought was impossible: he not only bested Joe “Stringbean” McConaughy’s seemingly unbeatable 2017 record, but he did so by four full days. Sabbe’s FKT time stands at 41 days, 7 hours, and 39 minutes. He ran through some particularly awful weather in the White Mountains and was up before dawn every day, finishing his miles before sunset.

The AT is 2,200 miles long. He averaged a little under 54 miles per day for more than a month with no days off.

Next frontier, adarq?

not strictly training related but this is so cool:

Paralysis is becoming less permanent — at least for some.

There’s now more evidence that stimulating the spinal cord can restore voluntary movement in paralyzed patients who haven’t recovered after other treatments. After five months of training coupled with targeted stimulation of nerve cells in the spinal cord, three people who had a severe spinal cord injury regained the ability to walk with varying degrees of support, researchers report online October 31 in Nature.

incidentally my mom used to edit that publication, science news, when i was in high school.

Frequent injuries have been a fact of my life since I started playing sports. I'm not talking about traumatic injuries -- I've only had one of those, a separated shoulder, and it was from a fall that would have hurt most people -- but more strains and sprains and aches that just always seem to be there in one part of my body or other. As a person who loves exercising and playing sports, this is incredibly frustrating. There has to be a reason, whether or not I can do anything about it.

My interest in training came out of an interest in physical therapy that itself came out of spraining my ankle six goddamn times. Time to get back into PT mode. This thread will be a repository for things I read about injury-proneness and what to do about it.

MOVIES & ENTERTAINMENT & SHeeT! / penn and teller: fool us
« on: September 16, 2017, 05:26:13 am »
For me, Penn and Teller: Fool Us is the greatest TV show of all time. Simple premise: Magicians try to do tricks that fool Penn and Teller, and the prize is that they get to appear in P&T's act in Vegas. Three reasons I love it:

1. Many of the tricks are incredible in their own right. Even the ones that don't fool the hosts are usually beautiful or amazing or both.
2. Penn and Teller are always kind and positive. The whole atmosphere on the show is one of supporting and sharing love for a weird, niche craft that is ultimately a really hard way to make a living for most of the people doing it professionally. Everybody feels good. It's wonderful. It's similar to the British show QI for that reason: everyone is rooting for each other. Watching people be generous is extremely gratifying.
3. When they get fooled, it's because the magician did something stupefying. Cases in point:

on a related note, i have become obsessed with david blaine, who is a genius.

I feel like this guy is Moderately fit non-athlete picks a random, hard goal that has minimal extrinsic value but massive intrinsic value. Goes and gets it.

ETA: he did a similar thing, for dunking, a couple years ago:

Holy shit! First time in 108 years! Somewhere, wherever he lives now, Steve Bartman is weeping just a little bit harder than everyone else around him.

26 days until Michigan's defense rips Hawaii's still-beating heart of its chest and eats it raw. The D was so nasty last year until Glasgow went down. We're going to be even better this year.

I just watched this video and got so hyped at my desk I started breathing audibly.

Really pulling for an all-Williams final. Probably the last time we'll ever see it! It's unbelievable how long Venus and Serena have dominated the women's game. Others have come and gone but the Williams sisters -- Serena in particular, the goddess that she is -- remain. They've both been pros for more than 20 years! That's fucking insane!

Also I want Federer to win again.

My cousin is an actor and writer and she is destroying it right now. I am really proud of her and excited for her! And feel like bragging a little to all y'all quasi-strangers! She's about to be in another play on Broadway, with Nathan Lane and some other famous people. And the most influential and famous theater critic in New York (and therefore probably the country) gave her play that just opened a raaaaaave. Jesus.

There’s a raw spot — one of the tenderest places on the continent of human emotions — that exists between laughter and pain. Make that between laughter and everything that feeds pain: rage, hatred, desperation, hopelessness, fear, even physical disease.

Such is the location of Halley Feiffer’s “A Funny Thing Happened on the Way to the Gynecologic Oncology Unit at Memorial Sloan Kettering Cancer Center of New York City,” a play that is as deeply felt as its name is long. To be literal, its setting is a sickeningly pink double room in the hospital of its title.

But as anyone who’s spent much time in similar rooms knows, antechambers to death are incubators for those guffaws that it’s hard to distinguish from sobs, places where you find yourself fighting a close battle with the urge to giggle madly. To give in to such an impulse, in such a context, would be very, very inappropriate.

Or would it? “Funny Thing,” which opened on Tuesday night at the Lucille Lortel Theater, makes a convincing case that hard laughter is an absolutely appropriate response, if not a socially sanctioned one, to those moments when life seems like too bad a joke not to respond otherwise.
