This morning, though my right knee was feeling wobbly, I did my morning run/walk and regained my previous best time, 11:21. I only got to the bus stop after Aston Street before breaking stride, but I spent more of the mile with my legs limber and stretching. The great impediment, I think, is my lungs, which is a bit scary (since my father died of lung disease), but pushing and making such progress as I can is presumably the best way forward.
