Boy, this kicked up my routine! I m a regular runner, and I tried this on my usual, difficult, hilly, five-mile loop. I jogged instead of walked for the warm up and sprinted during the fast intervals. I was DYING. Good music and motivation.

I didn t make it the whole five miles.

This one has a very good warm up session, long enough to get you going. Even though I like the intervals a lot adn I think it`s a great idea to have somebody timing it for you instead of trying to run and check the clock every two minutes I don`t think the music is motivating enough. I don`t like running but I use some other songs that really keep me going. Other than that a great idea. Keep the idea, change the music.
