Have you considered walking instead of running? I put the treadmill to maximum grade and walk. When I walk, I can easily read a book or listen to an audiobook. I am happy with the exercise without having to actually run. I can't remember the calories, but walking at 15% grade was equivalent to a pretty fast clip at 0%.
