I finally started my training yesterday! And it feels sooh good. Learning from Jaymie's experience, I started it slow. I walked 2k for 30 minutes then ran 1/2k for 4 minutes. This morning, when I ran five times around the tennis court before our tennis lessons, I was no longer gasping for breath. What a nice experience!
So if you're still deciding whether to run or not, simply go for it. Begin by walking first like what I did. Run only when you think you're ready for it. Don't rush. We have 1 year to prepare for this 5k fun run. Will you join me?
