Slowly slowly catchy marathony?

First run post-physio - four slow miles, around 9:30-10 minute miling. Some tightness in the soleus in the first mile, some ache in it by the end of the fourth, no pain. It's a small step but that's where all the giant leaps begin. I'll ice the muscle a bit and hope for the best it feels okay over the next 24 hours or so...
