Running?

I've never been a runner...in fact, I'm not a fan of cardio. I love weights and resistance training, but I need to get over the cardio distaste because I NEED it. Ethan starts preschool tomorrow from 9am-12pm and Zach will already be in the stroller (preschool is like a block away), so I'm thinking of maybe going for a jog. See how that goes. If I fit in a 30 min jog twice a week while Ethan is in preschool that would be great! 1 thing that might be a hindrance is the stroller though, even when I'm walking I'm constantly hitting the wheels with my feet! That sounds like an excuse, but we'll see if the logistics work out lol.
