For the new year I am going to add some road work to my training. I have never been a runner, so I am not sure how to start. I am in moderate shape...I train bjj 2 days a week, and go to my 'TMA' school another 1 or 2, so I am not starting from square one, but I am not in great shape either. I am 39, if that matters.
How many miles should I start with? How many days a week should I run?
