Personally, I suggest having a good rest.
Although running with a cold is not recommended, there will definitely be runners still running. What we need to do is to extend the time, not an hour a day. We need to watch it for 60 years instead of just one hour, so we suggest having a good rest. But Ken has to run, so he must obey the following neck rules.
Neck ruler
If you just have a cold and need to run, we can refer to the neck rule. If you have cold symptoms above the neck, such as stuffy nose, itchy throat and headache, you can do moderate jogging, brisk walking or core strength training.
Once you have a fever, chest tightness and limb weakness, you should stop exercising and have a good rest. It should be noted that if your headache is accompanied by chills and pains all over your body, it may be an early symptom of a fever, so don't exercise any more.
