Tony and Dee1P,
How are you both doing regarding your return to running? I am now 3 and 5 months out of having both of mine replaced, and hope to resume running. I am still on a rollercoaster with occasional setbacks with just walking (up to 4 miles a day) and resuming strength training (light rack squats, etc). I seem to have plateaued and see no way of running in my current state.
Cheers,
Gary
