Could getting a blister on your foot be the most important, valuable thing that ever happens to you as a runner. Crazy as that sounds.

I want to encourage you to ponder what your body is doing. Use that information as the appropriate feedback. Pay attention to the good side and if there's not a good side, just experiment. Just try something different.

Problems can actually help you figure out what really is going on and that might allow you to make the changes needed to correct them.
