Welcome to HCM,
Running is good exercise and you should continue.
But immediately you can not so much long.
Start with small distance and gradually increase the distance.
In your case due to sudden running big distance your calf and back muscles went into spasms and strain on muscles caused this problem.
Running in cold
atmosphere caught cough
Now get some rest for few days and afterwards start increasing running distance gradually.
In the cold take all precautions covering your body properly.
ok and bye.
