I don't really have a "runner's body", yet for my entire adult life I have found that, for me, a successful weight management regime must include running. The more I run the better shape I'm in.

I am currently walking to and from work for a total of 50 km per week. Yet even this distance does not yield the same results as jogging 30 km per week. The walking is an attempt to get me back into a shape that will allow me to run again on a regular basis.

All leading up to the Ottawa marathon next May.
