I've been working with a new coach the last half year, and because I have an injury history he only has me running 5 days a week.
We are getting in good work on the 5 days I do run - 45 mpw including tempo run, track workout, long run, strides, etc. All the important pieces are there, we have just replaced two easy run days with cross training (elliptical & bike). So I'm probably at 15 mpw less than I was doing before.
Except I'm getting the same results - he has me back to peak fitness. Actually the results may even be better, I'll be taking a swing at some indoor pr's in the coming month.
This has me thinking - what the heck is the point of easy runs?
