Day 8 - 2nd Week of marathon preparation

Today was the second week of the preparation for the marathon next year. Today I was supposed to walk for 5 mins and then run for 4 mins 3 times. I walked at 3.5 and then ran at 4.3 m/h easily, repeated this twice and started feeling proud of myself - wow GB what progress.....after that...I couldn't run for more than 2 mins the 3rd time, my body refused to..so walked at 3.1 for 5 mins and stopped.
I am 35 yrs old with a BMI of 31, almost inactive till last week when I started preparing. After today's workout, I feel I need to take it a little slow instead of trying to run at 4.3 mins. My advice - Take it slow - listen to your body.
I will be changing the table provided at the top of this blog to make it more feasible for real couch potatoes like me. Also, for people in northern California, I will attach the San Francisco marathon route to this blog so that we all know what we are aiming for.
