If just usually running or inhaling cold air and so on lead to intercostal muscle spasm, by deep breathing or stop running to a warm environment for a few minutes can be self-recovery, a little more serious may need 3 days; if the blood flow is not good or suffering from costochondritis, it may need 7 days, or even 10 days.
