Requirements and Expectations

• Experience: It matters not how many ultras or 100-milers you have run, nor how fast you are.
• Purpose: What matters is that you want to test yourself against the course and the time limit.
• Commitment: Take your entry into the race seriously.
• Selection Process: The process is private and will not be disclosed to avoid attempts to 'game' the system.

Awards and Fairness

IMPORTANT: THERE IS NO BUCKLE AS AN AWARD FOR FINISHING. There hasn't ever been a buckle offered since the race's inception, and as of this writing, there are no plans in the works to offer one in the future. If any of this is a problem for you, then there are more than 150 other 100-mile races to choose from, and you should choose to run one of those other races.
