We will be enforcing time cutoffs on the Dirty Dozen MTB Race (20 mile course).
Racers that arrive at the bottom of the Sallee Key climb after 9:30am will be cutoff. Racers that arrive at the bottom of the Dante’s Peak climb after 10:15am will be cutoff. If you don’t make the time cutoffs you will have your race number pulled and you will be directed to the finish line by course marshals.
