This is wonderful! What is kinda cool on my end is that I TOO have been thinking 'I need to start a running program again'. And those zombies apps sound cool. I personally have to have music in my ears while running otherwise I hear myself breathing...which is not unlike the sound of someone creeping up behind me! ;) The one with extra little bursts of exercises sound cool too! I usually just use the 'C25K' ('couch to 5K') app, though.
Good luck to you!!
