Rash? Really?

[shmoogrrrl]

I am doing the Couch to 5K program and today I did W5D2, which is 8 minutes running, 5 minutes walking and 8 minutes running. I run on my treadmill, and I did nothing different tonight from any other run.

Well, by the time I made it through the first 8 minutes, I had broken into this, for lack of a better word, rash. It was all over my hands, arms, stomach, chest and a small bit on my legs. I spent that 5 minute walk between runs trying to keep myself from scratching my skin off. I made it through the second 8 minutes (yay!) but by the time I was done with the cool down and stretching, I was miserable. Running cool water over it in the shower made it feel better and now, about two hours after I finished running, it is completely gone.

So does anyone have any clue what in the world happened? The only thing that I can figure out is that it was a heat rash, but I wasn't any hotter than I normally am. My basement is pretty chilly and I had the fan running on the treadmill so I had a lot of cool.

Thoughts?

Has this ever happened before? If you were to play a sport to the point of sweating at the same rate you were while running do you have the same problem?

The only thing I can even think of is that it was a reaction by your skin from the salt in your sweat but that would happen whenever you perspired, not only while running.

Were you wearing something new or different? I have allergic reactions when I sweat to different types of fabric (and especially if I switch laundry detergent).

Yea I would look for an allergen in your clothing that got spread over your body while sweating if you've done other sports/activities where you've sweated before.
