Today I started again with a brisk walk for 5 minutes and continued on alternating 60 seconds of running with 90 seconds of walking for 20 minutes. I did it twice yesterday, and plan on doing this for the rest of the week. 2-3 times a day. My goal is to get to a spot where I can run a 5K or even 10K race. Beautiful Day today, hoping to work in the yard this evening.
