THE RULES ARE SIMPLE

WEIGHT REQUIREMENT:

RUCK90 participants must ruck with a minimum of 20 lbs in a Ruck Vest or Ruck Backpack (Rucksack). This ensures the challenge remains true to its purpose, building endurance, strength, and resilience through weighted movement. No exceptions.

CHALLENGE DURATION:

RUCK90 is a 90-day, 100+ mile ruck challenge starting on the first of the quarter and ending on the last day of the quarter. Participants can join anytime, but their challenge ends on the last day of the current quarter, regardless of start date.

MINIMUM WEEKLY ACTIVITY:

Participants must ruck at least one day per week. Missing seven consecutive days will result in disqualification.

NO TREADMILLS:

All rucks must be completed outdoors or on an indoor/outdoor track. Treadmills are not allowed for this challenge.

LOGGING MILES:

Participants must log their miles and submit their progress regularly. Holding or "banking" miles, is not allowed. Post your rucks daily.

FAIR PLAY:

Participants are expected to log accurate miles and honor the spirit of the challenge.

LEVEL UP :

When participants cross 100 miles, they keep rucking and move into the 200 mile leaderboard. Each tier is a new challenge, and there is no limit to how far participants can go. Whether it's 300, 400, 500, or more, every tier represents personal growth and the determination to keep pushing forward until the very end.

RUCK YOUR RACE:

Compete, push yourself, and challenge others—but remember, this is your journey. Focus on rucking at your own pace, setting personal goals, and growing stronger with each step. Whether you’re aiming for 100 miles or 500, every ruck is a victory in your own race.
