For amateur athletes, developing the "know when to say when" intuition is tough.

“How do I know what pain is OK to train and race through and what might be injuring me?”Timothy Triage

We hear slogans like, “Pain is temporary. Glory is forever,” and I often see highly motivated, driven, results-oriented athletes (sound familiar?) who are concerned they are hurting themselves by ignoring pain while training. You might have a goal race coming up, or you might simply be worried about losing hard-earned fitness by taking time off What’s the best thing to do? Soldier on or become a couch potato?

You have to understand the difference between acceptable pain (or just plain hurting) and injury. So how does an athlete recognize the warning signs?

The “old sports guys” used to say that 4/10 pain or less is safe to train through. Obviously, the issue here is subjectivity. Athletes who expose themselves frequently to intense training are more comfortable with being in discomfort, so a 4/10 for them is quite different than for someone new to sport. However, here are some red flags:
