Over 6 Miles and NO UNDERWEAR!

yes, i thought i would try it. before, i had to have some type of running underwear on longer runs (over 4 miles) or i would gald or chafe, whatever you want to call it, i know you've been there. since i am trying to run with improved form when i grabbed a pair of my running shorts that has the little lining in them, i thought, what the heck. either this new form will help since i am running correctly, or it will kill me since i am running much slower during the learning phase. before it would have just been about an hour of torture. however, now, since i am trying to run based on heart rate, it would take me longer and that could be really bad. i ran 6.13 miles in 70 minutes and no undies, and no chaffing! the funny thing is, this is one of the few pairs of shorts that i have not cut the lining out of. i was actually running with these shorts over my underwear last year, kind of as an experiment. my left calf hurt from the time i started until mile 5. i kept trying to eleviate the pain by using the correct form, but couldn't quite get it down. finally around mile 5 i figured a few things out and the pain went away. after the run i really felt great, like i could have ran 4 or 5 more. my pace was 11:26, about the same as my 4 mile runs during the week. my average heart rate was up a little due to 2 big hills that i had to get up to get the extra mileage in. i did use some tips from the chirunning book and cd i have to get up the hills and they really seemed to make the hills go much easier. can't imagine how i will finally feel when i get this form down. thought of the day: if you don't have to wear underwear, why would you? don't worry, i will be wearing some sort of underwear, it was just a thought.
