Thanks everyone for all the advice. I ran back in the 80's(about 50 mpw) - just ran for fitness and fun. This is what I was going to try. Since I can run 32 minutes, a couple of times a week, run a shorter distance/time(maybe something like 20-25 mins) and 2 days run the 32 mins, then 1 day increase to 35 mins, then increase the next week so my 32 mins run would be 35 mins and then gradually increase my time/distance. What do you think about this plan?
