I am on week 3, and walk/jog on a paved trail in a wooded area in Atlanta (USA). Since it is 62 miles long, I turn around to go back to my beginning point after the podcast is done. So, I do the podcast again on the return trip. I also usually add two runs during the time for the first run's cool down and the second run's warm up period. I want to point out that I am jogging at a snail's pace, but do feel that I am truly spent when I am finished.
Today, I attend my first session of a fitness bootcamp. We just did fitness assessments today, but they were tiring nonetheless. What I am most excited about, and have to give thanks to the C25K program, is that I was able to run around the track 4 times without stopping. It took me 15min 26sec to run a mile, and I was lapped by quite a few others, but I didn't think for one second to stop my trot.
I would like to hear how you've customized your C25K and exercise plans.
