This years race capacity will be limited to 350 RUNNERS, which is an increase from our 2020 limited entries, however we still anticipate this race will likely reach capacity long before online registration closes September 26th, so don’t slack if you’ve got those Monsterish vibes - commit and sign up! In the event it does fill, a wait-list will be generated on a first-come-first-serve basis.
