Yesterday my hemoglobin was the highest I’ve ever, ever seen it since I became obsessed with my hemoglobin seven years ago. Proof: And it wasn’t until I got home from the doctor that it dawned on me: My hemoglobin is 13.1 just days before I’ll be running 13. 1 miles in my first half-marathon. This has to be a good omen. Even my red blood cells are ready to run.
