Why This Matters

This isn't poetry. It's a spec sheet. When you understand the oxygen debt, the glycogen burn, the heat rejection—you understand why the record stands at 3:43.16 and not 3:40. The body has limits written in chemistry. The runner is just the vessel that finds them.

I built this because the town is chasing ghosts—Odysseus, Troy, Helen. I'm chasing the mile. The only god worth worshipping is the one that breathes.
