Achilles tendonitis is also very common among high mileage runners. Since i wasn't a runner until recently, I didn't take the good precautions I need to prevent injuries.
One of my main goal was to run most km in 1 week. the fact i never stretched after running lead to developing heel pain.
Now it had been a full week i am not able to run. I tried to run an 8 km last night, with a lot of pain i made it back home.
I am not sure what to do i just hope the pain goes away.
