For ipod gym users

I don't necessarily take it to the gym, but I do go running in the mountains about 5-6 times a week for about 3 miles a run. I'm a big guy (6'1", 190 lbs.), but I don't sweat excessively. I have never had a problem with the earbuds. I have also played tennis in the rain 2 times with it, for about 4 hours, and water welled up in my ears so much that the sound of the buds was muffled by it. They still work great weeks later. I use a mini, and I simply clip it to my shorts when running, and it works great. I've never had it skip or anything. If it weren't for the ipod, I probably wouldn't be running nearly as much (running bores the hell out of me, but my pool hasn't opened for the summer yet).
