Bad run with a sore ankle

Tried to run a 6.5 mile route and learned a valuable lesson. Keep a day of rest after speed workout and sore ankles dont do good while running. Whereas maybe sore calf quads etc can be managed, its not the case with ankles. I averaged 13mi/miles and the soreness got real bad 2 miles into the course so I had to do a lot of walkins and slow jog to make it back. Did a total of 5.5 miles of the planned route
