Q. After a 10-12k run, I often feel a burning sensation in my lower calf where the Achilles tendon goes into the calf. It eases with movement but is there a way I can avoid the discomfort?
A. This is most likely to be an overload issue in either your calf muscle, Achilles tendon or the area where the tendon blends into the muscle. If you find your calf does not bother you on shorter runs but does after the longer ones it’s likely you have reached the point of fatigue for your calf and the muscle is no longer able to perform. This can cause irritation of either the muscle or the tendon giving it that inflamed feeling. Movement will help this as it gets lots of blood pumping around the area and will flush the swelling away. Icing your calf at the end of your run will also help.
I suggest testing your maximum calf raises to fatigue on both your affected and non affected leg. If there is a difference then you know you need to work on strengthening that calf to ensure it can keep up with the distances you are wanting to run.
