In Which I--Wait, What?

I started using the Couch to 5K app on my phone. The idea is for you to train to do 5k in 30 minutes. I've done the C25K thing before, but never on my phone. So there I am, my timer counting down (you didn't really think I did over two miles in fifteen minutes, did you?!), running along (okay, running for 60 seconds and then walking for 90. Leave me alone, I'm taking baby steps in my fight to not be fat here, mmmkay?), and my phone chimes to tell me I'm done.

Um, what?

According to my calculations, 2.18 miles is roughly 3.51 km. That's 1.49 km less than what I was trying to attain.

Even my phone app thinks I'm too much of a wimp to do a full 5k.
