Progress is a funny thing. Progress is also a difficult thing to define. There is “progress” in all three scenarios below. But at what cost?

If you are training for a marathon as a wife and mom of three kids—and spending time away from your kids in a way that makes you feel remorse.

What if you are working on your marriage so hard that you never hit your planned cycling workouts? You feel your training and race goals slipping through your fingers like sand. And as a result, you are miserable.

What if you are hitting all your workouts, and getting faster, but you are just too tired to care about the other things in life? You have no “real” relationships, no time for anything else, and no fun outside of triathlon? You feel alone.
