My shin is beginning to feel like I could abuse it again, and I slip on the ice. I fall down. I go to the hospital. I get casted for a fracture. Four weeks is not too long, but my first real race ever is in five weeks.
I'm going out to run anyway. I figure the throbbing will go away soon. I'll give it a few more days and get back outside.
Obstacles. Gotta love them, I guess.
