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 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 230 (total) runner limit.

Hardrock 100 Qualifier

As the Hardrock Hundred was canceled in 2019 and 2020, the current qualifying race for the next Hardrock will be the 2021 Mogollon Monster 100 Mile. This finish will go towards the 2022 Hardrock lottery. See additional details here: Hardrock 100 Qualifying Races

The Monster is NOT a Western States 100 qualifier.
