I have no idea how close to accurate my pedometer is for what I just did. I can use it referentially, though, and see how my time/distance changes proportionately.

1st session of c5k:

8 sessions of 60 seconds jogging, 90 seconds walking, for a total of 20 minutes. I walked for a 4 minutes before starting, and about 3.5 minutes when I finished. I went over on a few of the cycles:

3551 steps
1.457 miles
127.6 cal
28:49 minutes
