Recovery method: longer running instead of rest

After yesterday's run I was concerned about my left knee and its recovery. It's been almost a month since I aggravated this knee. The injury was probably caused by too much distance and hard training prior to my half marathon. Since then I've kept my runs relatively short and have tried to do more low impact activities like elliptical and biking. That seems to be working.

This morning my knee feels even better than it did before yesterday's long run. There was an article in a recent Running Times that said easy long runs can be preferable to resting for recovery from minor leg and knee issues. Supposedly the easy running over longer distance helps oxygenate muscles. Considering how well I feel today, this method may have merit.
