QUALIFICATIONS : 100 Mile only

Qualifying for The Monster: The 100 mile distance is not an easy race and as such, we have a qualification standard for the race. All entrants will be required to have completed, at minimum, a 50 mile race or greater before race day. Do not be fooled though, this race course will absolutely make you earn every mile you traverse. Come prepared, know your course, and tackle the Monster this September. ​

REGISTRATION

Registration for the 100 Miler opens in the beginning of December. Online registration is available through Ultrasignup.com and we have a mail-in entry if you prefer. There will be a 250 (total) runner limit. The Marathon distance (42 Km) will open in April.
