Brr... I'm freezing!!!

Well, the last two long runs I've done I've noticed a new phenomenon that I've never encountered in my experience as a runner... I'll usually cool off for a few minutes after I've changed out of all my ultra-sweat-soaked workout clothes and then go shower. Well for the second time in as many weeks, I spend the entire length of my shower so cold... it seems like I just can't get the water warm enough to overcome how cold I am. Since I've only noticed this for the last two weeks during my long run days, I started putting two + two together today. Thinking about it, I realized that this is probably not a unique experience... after all they give marathon runners space blankets at the end of a run. So, I ended up trying to poke around online to see if I could come up with the answer.
 

Here's what I've come up with so far:

1. I'm probably letting myself get too dehydrated during a long run. I'm not sure of the exact physiology here, but everything I've read in different articles and in various forums suggests that, especially for long runs, you need to make sure you replenish your fluids during the run.
2. I'm probably not getting enough nutrition during long runs... again it affects your body's ability to regulate itself. Apparently, you should also not be having whole "natural" foods during or immediately after (w/in the first 15 minutes or so) a long run, it can be hard on your stomach. Hence, the need for energy gels & cubes. (Okay, I confess to having a kind of d'uh moment on this one...)
3. Your body heats up during a run, but then when you stop running your body immediately cools off, dropping several degrees rapidly... and apparently this can include dropping down to below 98.6º
4. Don't forget the problem of wet clothes. Tech clothes will help with wicking moisture away from your skin during the run, but after a run, wet clothes are still, ultimately, wet clothes whether they're 'tech' or not... and sitting around in them for too long can also lead to a reduced body temp. Like I mentioned above, I usually change out of my wet clothes immediately, so this most likely isn't where I'm getting chilled, but it is certainly something to keep in mind..

Now that I've learned a little bit more about long runs... stuff, I confess I probably should've known before setting out on one... I will take some extra precautions during next week's run and let you all know if I think it is helping me keep my body a little better regulated.
