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. This is different than the last three years as Aravaipa has now directed this beauty of a race since 2016 and believe we are more prepared for the logistical battle of putting on this race. Combine that with the same HAM Radio team and MedStar Solutions medical team joining us year over year, we have taken out specific race qualifiers. 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 is now open. Online registration is available through Ultrasignup.com and we have a mail-in entry if you prefer. There will be a 230 (total) runner limit.
