How the Hardrock 100 lottery works

  • Separate draws for never-finished and past finishers.
  • Each of those is split into men's and women's pools.
  • Never-finished tickets double for every prior unsuccessful year, so odds grow exponentially with persistence.
  • Past finishers draw from a linear pool — no doubling.
