Q1:2026 STARTS IN:
CAN YOU RUN 100+ MILES
AND STAY CONSISTENT FOR 90 DAYS?
RUN90 is a 90-day, 100+ mile challenge built to push your limits, elevate your consistency, and strengthen your community. The heart of RUN90 is simple: lace up, get outside, and put in intentional miles. No special gear. No complicated programming. Just steady, disciplined movement.
In RUN90, participants commit to running a minimum of 100 miles in 90 days, tracking progress and building momentum week by week.
But RUN90 isn’t just about mileage. It’s about showing up, even on the days you don’t feel like it. To stay active in the challenge, every participant must run at least one day per week. The rhythm of the challenge builds discipline, sparks personal growth, and connects runners of all levels in a shared pursuit of progress.
Whether you’re brand new to running or a seasoned athlete, RUN90 gives you a clear, structured path to improve your endurance, strengthen your mindset, and earn exclusive milestones and swag along the way.

THE RULES ARE SIMPLE
CHALLENGE DURATION:
RUN90 is a 90-day, 100+ mile running challenge starting on the first day of each quarter and ending on the last.
Participants may join anytime, but all challenges end on the final day of the current quarter, no matter the start date.
MINIMUM WEEKLY ACTIVITY:
Participants must log at least one run per week.
Missing seven consecutive days results in disqualification for that quarter.
NO TREADMILLS:
All miles must be completed outdoors or on an indoor/outdoor track.
Treadmills do not count for RUN90.
LOGGING MILES:
Participants must log and submit their run miles consistently so progress can be tracked, validated, and celebrated.
FAIR PLAY:
Accuracy matters. RUN90 relies on honest reporting and integrity from every participant.
Run your miles. Log your miles. Keep the challenge authentic.
LEVEL UP:
Once participants hit 100 miles, the challenge continues.
They move into higher mileage tiers — 200, 300, 400, 500+, and beyond.
Each tier represents deeper discipline, stronger habits, and the determination to keep pushing to the very last day of the quarter.
RUN YOUR RACE:
Compete with others, push your edge, and strive for more — but above all, run your race.
Your pace. Your progress. Your growth.
Whether you finish at 100 miles or fight your way into the 500+ mile tier, every mile is a win and every run is a step toward a stronger version of yourself.
DISCLAIMER:
By participating in RUN90, you acknowledge that running is a physical activity with inherent risks, including potential injury. You accept full responsibility for your own health, safety, and well-being throughout the challenge. By joining, you agree to follow all RUN90 rules, including mileage submissions, activity requirements, and disqualification policies.
Participation in RUN90 releases Buffalo Mentality, its affiliates, and its organizers from any and all liability related to injury, harm, or issues that may arise during your involvement in the challenge.

How do I stay active in the challenge?
You must ruck at least once every 7 days. If you go 7 consecutive days without a ruck, you disqualify yourself from the challenge.
What happens if I miss a week?
Missing 7 days in a row means disqualification (DQ) for that quarter. Don't worry, if you DQ, you can start the challenge over within the same quarter once for free, however you lose any mileage you previously tracked in the quarter.
Can I use a treadmill for my rucks?
No. Rucks must be completed outdoors or on a track (indoor or outdoor). Treadmills are not allowed.
Do rucks have to be a certain length or speed?
No. Any distance counts toward your mileage. There’s no required pace. The goal is consistency.
How do I earn the custom RUCK90 T-shirt?
You must complete at least 100 miles within the 90 days to earn your custom tier T-shirt. The shirt design reflects the mileage tier you reached.
When do I get my T-Shirt?
All T-shirts are ordered and shipped after the challenge ends. This ensures your final mileage tier is locked in and you get the correct shirt for the distance you completed. Shirts usually ship within a few weeks after the 90 days are over.
What happens if I don’t hit 100 miles?
You’ll still gain the experience of the challenge, but you will not receive a T-shirt.
How are miles verified?
Miles are tracked through your submissions. We encourage honesty and accountability. This is a personal challenge to develop healthy habits and consistency this is not a competition.
