It has been nearly 3 years since I participated in a timed marathon experiment. It has been much longer than 3 years since I actually trained for any event. I have “trained” for several events before, including the two marathons – Marquette, MI and Madison, WI, but without a formal training plan. Back then and until recently, I was basically hopping from one event to the next using the performance in one as the baseline for the next. Such an approach worked pretty well in the first few years of getting into running because there was a LOT of room for improvement – so much so that anything and everything I tried, small or big, often led to newer personal best times.
