A safety checklist for deciding whether to keep running or stop, not a self-diagnosis chart.
The heaviness you feel after a run and the pain that should stop you immediately can look similar but call for completely different next steps. This isn't a chart for diagnosing conditions โ it's a sequence of signals to check before deciding whether to keep training.
It moves from whole-body fatigue through localized pain and sudden onset pain to gait changes and emergency signs. If a symptom matches your situation, follow the suggested response, but if it persists or worsens, prioritize a medical consultation over anything on this list.
01
Whole-body fatigue
If your entire body feels heavy along with poorer sleep quality โ not just one area โ it's more likely a sign of insufficient recovery than a specific injury. Track your recent sleep and workload, and if a day off doesn't help, scale back your training further.
02
Even soreness on both sides
Symmetrical soreness after a harder-than-usual session is often a normal response, but it's a different story if walking or climbing stairs also feels uncomfortable. Watch whether it eases over time, and push your next run back if the discomfort is significant.
03
Pain concentrated on one side
Discomfort that repeatedly lands on one side or one specific spot is a different signal from general fatigue. Note when it started and whether it affects walking, stop running for now, and consider a consultation if it lingers after rest.
