Where is the Trail Running Capital of North America?

What are the criteria we should use to crown the capital of North American Trail Running?

Here are some of my thoughts.

Number of elite ultras

Number of non elite ultras

Number of elite runners

Varied trail terrain

Number of dirtbags

Number of bandit races

Trailhead proximity to great restaurants 

Which of these do you like? What would you add?

Why am I doing this?

1. Fun

2. Funner
