At the end we were supposed to "save time for a 10 min mile." I got on the treadmill and felt pretty good, so I decided to run at 9:13. At about 1/4 mile Tim came around and started increasing our incline- from 0 to 2. Although difficult, I felt that I could still handle it. It wasn't until he went from 2 to 4 that I felt that I was going to die (not in the literal sense of course). I moved the pace to 9:45 just to keep up. I did have to step off the treadmill for 10 seconds, but I got back on and finished. He waited almost another 1/4 mile before taking off all of the incline. Needless to say, I was really tired when it was all over.
