Which day is best to add workouts for injured runners

This morning I was on a webcam call with a runner who had healed a fracture and started running again. He has been running every Monday, Wednesday and Friday, with cross-training in between.

 

Now he is ready to add a fourth running workout to his weekly training schedule. 

 

The question is: 

 

“What day of the week is best to add an additional run, because I want to make sure I don’t overload the healing tissue and re-injure it.”

 

Today on the Doc On The Run podcast, we're talking about which weekday is best to add workouts for injured runners.
