weird post-LR episode

Dave Tallo

Did my long run last night.  Went a bit harder than normal, but nothing insane.  I've done the distance and duration - what - maybe a few hundred times before.  Took in the same amount of water and gatorade as every other time, ran the same course as always, temp was perfect running weather. 

I have a bit of nausea afterwards, but force down a post race meal, get home, get oiut of the wet running clothes, and then I'm freezing.   It's room temperature, but I'm shaking violently from the cold.  I put on track pants, two shirts and a sweater, and eventually have to crawl into bed under a duvet and wool blanket.  And I'm still shaking.   In the end, it takes about 30 m for this to cede.

What happened?  At the time, I was wondering if it was hyponatremia, but the fluid situation wasn't anything out of the ordinary.  Any thoughts?

Dave - I'm wondering if your weight is down a little. If so the same amount of fluids could make you cold. I'm down in Tampa, FL and keep an ice chest in the car trunk to help replenish. I can easily put down 60-80 oz of cold liquid after a long run which means I've replace fluids that were body temperature with ice cold fluids...and I sometimes get chilled...but that's a good thing for me. I keep a gallon and a half of tap water in the trunk too. That's for the instant shower when I'm done running. Wet clothes are not a big deal...they are either wet from sweat or from the shower. Anyway, it doesn't sound anything like hyponatremia...but something was different. If your weight was not down, was the humidity down? Or maybe you were just on the edge physically and this particular run took you over...nothing a little rest shouldn't cure.

Also, see how you are feeling today / 24hrs later...could be onset of something...

Doesnt' sound like hyponatremia to me either.

What was the temp during your run and what were you wearing? What was the color of your urine post-run?
And how are you feeling now?

@Dave - I've had similar in the past during MTB XC races (90mins at full-gas type stylee) - even though its 85 degree temps & I'm sweating, I still got the chills - BIG warning sign. Usually goes once you stop, hydrate & get solid food inside - see it as being at rock-bottom.
