C25K Week 3

Week 3 has been really good. I feel like I can just keep running and running. I'm feeling stronger in the legs and my knees have held up really well. It's suprising how quickly the cardio side of things improves. Right now I feel it more in the legs (which are so out of shape) than in the breathing side.

Week 4's plan is:

Brisk five-minute warmup walk, then:
Jog 400m (or 3 minutes)
Walk 200m (or 90 seconds)
Jog 800m (or 5 minutes)
Walk 400m (or 2-1/2 minutes)
Jog 400m (or 3 minutes)
Walk 200m (or 90 seconds)
Jog 800m (or 5 minutes)
