I'm hoping to run in the Disneyland 5k in January. Since some of my family will be running as well I don't want to be the lazy unfit bum who walks the whole thing, so I started the Couch to 5k plan. Workout One consists of a 5 minute walking warm-up and then alternating 60 seconds of jogging with 90 seconds of walking for 20 minutes. I knew I had a little endurance so I cut the walking portion to 60 seconds. I'm such a lucky girl cause my hubby offered to do it with me. We did it! The whole 20 well 25 minutes including the warm-up without stopping. It was actually kinda fun counting down the intervals. We ran without iPods since I read you can get frustrated trying to hard to stay in time with the beat of the music.
My only problem, I always get a stitch in my side. What causes this?
