Is any weather perfect for a marathon?

Hi bloggers,

    Last Saturday, Olathe held its annual marathon.  A guy from Minnesota won the race, ran it in less than 3 hours.  I ran the half-marathon, 13.1 miles.  My friend, Ric and I finished finished 400th out of 600 some odd runners.  The winner ran the race in about an hour-15.

    As you can see in the pic, it was cloudy and cold.  Pefect for a marathon or a half-marathon.  I found this article on-line, on research done into the best weather for running a marathon.  It comes from www.poweringmuscles.com.

    "Researchers gathered many years' worth of results and weather data from six major North American marathons and performed stastical analyses to determine the effect of air temperature on finishing times among runners at various levels of performance. Specifically, they looked at year-to-year comparative finishing times of the top three male and female runners at each event, as well as the 25th, 50th, 100th, and 300th finishers.

The results showed a clear trend toward faster times at colder temperatures.  For example, the finishing times of male races winners were, on average, 1.7% slower than the course record when the air temperature was between 34 and 50 degrees. The finishing times of the top male runners were 2.5% slower than the course record, however, when the temperature was between 51 and 59 degrees. And at higher temperatures, finishing times fell off even more dramatically.

Runners at all levels were slowed by warmer air, but higher temperatures had a smaller effect on faster runners. The ideal marathon temperature, according to these analyses, was a bone-chilling 41 degrees. Think about that when you sign up for your next marathon!

    My next marathon will likely be one in Maryville, MO in June.  I'm thinking it will be a lot warmer than 41 degrees.   Also, wanted to pass along this sunrise snapshot from Mike Penley  in Gilman City, Missouri.  Gilman City is up on the Harrison/Daviees county line.

   

   Great picture, Mike thanks!

Have a great day,

Brett

Marathon, huh? At least you beat 200 other people. Well, that is all I gotta say about that.Byan.  **** Bryan, Yes, it will be my second.  KC nearly killed me last year but I want to try it again and correct some race day errors.  Brett

Fascinating research - thanks for posting it.

If I remember right, it was realtively warm last year when you ran the KC Marathon (my wife and I did the half that year)...but June has the potontial for being even warmer than that I suppose.  If you're looking for another half to complete as part of your training, the Lawrence Half Marathon is coming up on 4/20.  We've run that race the last couple of years and it is a pretty fun course (save the cobblestones in the old part of town and the climb up Mount Oread).

Temps were in the upper-40s at the start of the Twin Cities marathon when I ran it...but finished in the upper-50s or low-60s.  It was a bit on the warm side by the end, but it worked out relatively well.  I can't complain since I've seen some marathons run in conditions significantly worse than that.

I'd say my ideal running conditions are probably temps in the low-50s, a light (5-8mph) breeze, and some filtered sun which accomadates a light shirt, shorts, and sunglasses.  What about you, Brett? **** Notes, thanks for the heads up on the Lawrence half, Last Saturday was about as good as it gets for me.  Low 40s & overcast.  I did a 20 mile training last year in Lawrence in similiar conditions hitting Mt. Oread at mile 18 and I was cruising.  Standing at the start line in KC with the temp rising through the 50s by gun-time I knew I was in for a tough race and it played out that way as by the end of my run (5+ hours later) it was sunny and 71.
