Fitness Plan - Revised

I've been struggling to get motivated to get myself back into running shape. It's been hard. I've decided that I will aim for daily activity - to me that means 5 days each week. After picking up my bike on Wednesday, I took it out for a short twenty minute ride on Thursday evening. Today, my son and I went for a walk of about an hour. We're going to run with an area club tomorrow morning. That will be three days in a row.
My hope is to integrate more activity into my day, and to keep it varied. The plan is to gradually build my aerobic condition while I strengthen by legs. Once I am comfortable running, I'll try to do that 3 or 4 days a week, with other activity on the other days.
I hope this will also help motivate me to drop some additional weight - I'm at about 185 lbs., I'd like to get down to about 165 by year end.
