I haven't been running a lot lately because of my business travels overseas. Then I got sick; then I traveled again; then worst of all, I hurt my back. I didn't run at all for almost two months. My back is better now, but I don't feel fit at all. I badly wanted to go back to running but I didn't want to risk injury. So, I decided to become a beginner again and start at the very beginning - Day 1 Week 1 of the Couch to 5K program . Today, I did a 5 minute walk, 1 minute run and 1.5 minute walk for 20 minutes, and then a 5 minute walk. I didn't get bored or anything and more importantly my back didn't hurt while I was running. I was just glad I was outside running again. I plan on going through the whole 2-month C25K program and am looking forward to joining a 5K soon after.
