We all talk about it, but my experience is that more than the general public, runners are much more attuned to conditions mother nature dishes out, especially here in fickle New England. Studies have indicated the ideal conditions for running are temperatures of about 45-55 Fahrenheit. But as in almost every other facet of the human condition, there is a wide individual variance around this figure.
Some runners seem to prefer hot weather, while others seek the cold.
Here in New England we have enough during the year to satisfy both types. Far be it for me to offer advice for running in weather, other than to say that long distance and temperature extremes are a very bad combination. Like many other runners, I've become something of an amateur meteorologist. Here are a few odds and ends I've picked up along the way. If you think you've worried about the weather as a runner anticipating a big race, try being a race director - then you'll really know about weather worry.
