5 km... Oh Dear...

I'm always pretty embarrassed at how bad my cardio is. I've never been someone who ever had a desire to run. However, I guess it's the best way to develop endurance. There's a few races in Edmonton that actually seem like fun and I'd actually like to try them. Next summer I'd like to run Color Me Rad and then do the Zombie Run in the fall. Today I downloaded the free Couch to 5km app and went for a jog/run. I'm not going to lie, I felt like crap. I know my posture must've been wrong because my shins and calves hurt, so I have to get some advice on that, and I felt really weak afterward. The app is an eight week program so I'm going to keep going with it as I'm sure it will get way better. Why else would so many people do it.
