6 mile run today on the treadmill in just under an hour - the furthest I have run since the end of August - so good progress! No back pain or leg stiffening during the run - I just found it very tough due to my lack of running fitness. Feel fine now and had a good stretch.
My QL and hip were tight this morning so there is definately some sort of correlation with swimming and my injury. I have been in contact with my physio and going to see her later this week to get to the bottom of it.
