Just outside of Toronto, Canada !

I agree with all what was said above. When I was on the program I was begging my phone to say 'one minute remaining'! What is it that's stopping you from going longer - is it boredom or just a feeling that you can't go on any farther? Whenever I feel like I can't go on, I focus intently on deep breathing to get myself back on track. When it's boredom, I just change the song.

I think I have experienced this before too. A couple years ago I brought it up to my doctor who ran an ekg but nothing was wrong. I've recently got back into running and I think that it's caused by your breathing technique. Next time you experience that pain, focus on deep 'belly' breaths & it should clear. It's worked for me!
