Gotta be, has to be dehydration. It doesn't matter that you run with a drink bottle. If you are a little low when you start, don't take enough in when you run or just as importantly afterward then the dreaded 'D' WORD can get you. I've had the same phenomenon and it always comes down to hydration.

I experienced sever "shakes and shivers" after a race in December. I am on a low GI diet and neglected to consume high GI before and after the race. Within a few hours I was in bed trying to get warm and it was 28C outside.
My sports dietician recommends gatorade and a banana after a long run.

Interesting issue, I have also experienced chills, but I don't think it is dehydration as I usually run with a lot of water.
Not sure about the damp clothes as I have got back from a run in the rain and jumped straight into a hot shower and experienced chills whilst standing in the shower :rolleyes: and I felt quite warm on the run.
Could be lack of glucose, I will try and experiment with that.
Whatever the cause, it doesn't seem to have caused me any problems.

My husband cannot understand that I can come home from a run all red and sweaty, then 20 minutes later I'm shivering and covered with goosebumps. After a long run it will take me a good couple of hours to get back to normal.
I would have to agree with KT that my (also made up) theory is that I have used up my energy and can't get warm (blood sugar, etc). I will still be freezing after a hot shower or bath. Eating a good meal soon after (and probably before too) helps.

Quick shower, warm food and sugary fluid, put on your track suit to keep yourself warm for a few hours.
Tell hubby he is lucky to have a fit wife, and he can run the ship for a couple of more hours while you spoil yourself with a post run feast, and do a pilates stretch to music.
If you are slim, your body will chill quickly when your blood reduces from 39-40C running temperature back to normal 36-37C.
You are more likely to chill if you have not eaten much solid food in the 3-4 hours before a run.
A lot of the core heat comes from a tummy full of warm food.
If the tummy is empty, and you do a long run, you are depleting things further.
Your blood will be hot from the muscles working really hard and giving off heat, but as soon as you stop, heat production falls away quickly if you don't remove wet clothes and have a feed.
I once had a sick baby, and I was surprised to see how much her temperature changed during 24 hours with hourly checks.
Certain times of the day, you are more vulnerable to chilling after exercise, but it's got a lot to do with how much food is in the stomach, and what clothes you are wearing.
Track suits were designed to keep you extra warm for several hours after a long run, whilst you are recovering.

I really don't think dehydration is the answer because I do drink at least 2 litres a day, plus the water I run with. I've tried tracksuits after races and it does delay it a little, but I still need a shower to warm up...
It could be glucose related, because I never eat before running, so I'll try that and see how it goes. The low blood pressure idea sounds promising too because I mine is always on the low side of normal. If anyone has any other ideas I'd be glad to hear them...

This is a report back from someone who regularly got 'the chills' after a race (not training runs).
After the Welly half marathon last week I got stuck right in to a bag of fruit bursts (fruit flavoured chewy lollies) YUM!! No sign of the chills, though admittedly the weather was warm.
Today's after-work 5km at the Wellington Waterfront. After the equiv race 2 weeks ago, definitely an onset of the chills while waiting for the bus home. Today I glugged a bottle of 'e' (sugary fruit drink) and no chills despite it being a cool evening.
So my vote goes with the sugar theory, I am now prepared with a fix and thanks to those who contributed here. :-)

It happens in the summer too but not nearly so bad of course. I always take a snack or sweet drink to have after training or racing.

The theories seem mixed from this thread and another: http://www.coolrunni...p?showtopic=363

Interesting though. Thank you for the link.
I wish we could share and discus more articles here on Cool Running. I learn a lot from reading and then discussing the ideas with others and hearing about their experiences.
I firmly believe in my case it was low blood sugar. Sometimes , especially if it was cold outside I would be shivering, and my hands and feet were white & numb driving home after training. Once I started taking a drink (juice, choc milk, gatorade) and drinking it immediately after training I haven't had any more problems with it. Even some fruit seems to stop it.
I also believe having some sugar after training helps keep me from getting sick too. I have been much healthier since. I can't remember the last time I had a cold.
