Seven weeks with this sucker but it seems to finally be on the mend. Maybe like 90%. I'm planning to begin slow running on Saturday, and plan to go at it every other day to see how the AT responds. All of these early/slow runs will be done on a treadmill. Anyone had any issues with returning from AT while using a treadmill? I don't have access right now to anyplace flat, and that'll be the case for another month or so.
