What weather will put you off training?

Been out in my shorts and base layer only in all the wind and rain for the last couple of weeks.  If I don't, then I'll be sitting around moping all day and reading about how someone had a great run that morning!  Still a bit warm though...only had icy pavements once recently.

Never know when a race you enter might have the same weather conditions, so best to get used to it.

I don't mean to be a pedant... but it's just the way I am.

Hyperthermia is OVERheating... "Hyperthermia, in its advanced state referred to as heat stroke or sunstroke, is an acute condition which occurs when the body produces or absorbs more body than it can dissipate"  -Taken from Wikipedia

Hypothermia is probably what you meant. Did you know that when skin is wet, heat dissipates from it 25 times faster than when it is dry? Hypothermia has been known in cases where people have been caught unprepared in sudden, icy showers. This combined with the above described wet skin effect results in a dangerously quick drop in core body temperature.

 Pneumonia however is a different kettle of fish entirely... it's viral/bacterial and is an infection rather than a "state" as the other two are. Pneumonia is an illness whereas the other two are "conditions" that simply represent a culmination of various symptoms.

If it's a combination of strong winds and heavy rain, i'll use the gym or go for a swim instead.

Find it uncomfortable running in anything above 20 odd degrees, so during the summer I tend to run late evenings.

 Not sure I believe what some of my family / friends say (who dont run) - that by running in cold / wet / windy conditions we are more likely to catch a chill / cold / flu, etc. Not had any of these for a long time, yet my colleagues who are mostly sedentary seem to always have a cold / virus / flu etc. Anyone else find this?

Life's too Short - thats too funny by half.

I very rarely get colds & flu nowdays been running consistently now since 2003 and where before i'd get them 3 times a year. In recent years i'd only catch something once a year normally in Oct/Nov. so far this year nothing. Coincidently been running more this year than i have ever done

Yet others (non runners) seem to get them regularly

it's that fine balancing act...the running increases your body's defences...but over a certain level you're battling going the other way.

However, so far so good this year... 

when i ran 25milesa  week i'd have a cold a few times a year..not really had one this year despite doing 40-50 these days...

I go out whatever the weather although I do have to push myself a bit more to go out when it's chucking it down.

I hate to brag, but living in Winnipeg, Canada, it's stupidly cold for months on end. Last winter, I found that I could run for about 75 mins at -35 degrees C, if it wasn't too windy. There was one occasion when I was coming home from work, and the windchill was approaching -50. That was cold like you wouldn't believe.

AreThoseMyFeet - I can vouch for that. I was in Winnipeg in 1997/8 for 4 weeks over Christmas and New Year and I couldn't believe it - ludicrous. The friends I stayed with plugged their cars into heaters to stop the oil freezing (I think) and started the car with a key fob from inside the house to warm it up.

Also lived in Chicoutimi, Quebec for 6 months in 1990/1991 - not much warmer there and much more snow - I couldn't believe it. Those were my student days though so only running I did then was between pubs.

Oh yeah, all the parking lots have rows of plug sockets for the cars, and remote starters are very popular. I don't drive though, so it's the heated bus shelters that I'm thankful for.

However, I'd take stupid minus numbers over stupid plus numbers any day of the week.

Personally, I'd call those gadgets for running on ice ice cleats. The stretch-over types are sold in ordinary shoe-shops here in Norway. They help prevent people breaking hips in the winter. It's been minus here for a few days so I've just been getting used to my Ice Bugs again, training for a marathon next March. My other half uses ASICS Arctics. The main differences are that the Ice Bugs protrude whereas the ASICS are protected by the tread and are replaceable.

Anyway, on the original topic, I agree that wind and driving rain, or a sudden icy wet shower are the worst.
