Latest run

Yesterday I did a 10.68 mile run/walk and had no problems with my recent calf strain. I am slowly increasing the run duration and decreasing the walk duration. Last week I was in Florida and while running I could feel my calf muscle get tight and sting a little bit so I am being cautious this close to the half marathon. I had been on pace to run the half on a 2:20 pace but that looks too aggressive at this time-better slow go than no go. I have been using arnica gel on my leg,using the foam roller and the stick(I take the stick to work). This is the first time using arnica gel so I am not sure yet if it is helping.
