Congratulations on scoring one of the coveted spots at the 2019 Garmin Dirty Kanza. The fact that you would even want to tackle an event like this means you have a couple screws loose. We're going to get along just fine.

If you want to conquer the Flint Hills you're going to have to be strong both physically and mentally. The Sufferfest has you covered.

    One App. Everything You Need to #BeatYourBest.

    Whether you have your sights set on the top step of the podium or a personal best, The Sufferfest will get you there. With a huge library of structured workouts designed by elite coaches, connection to devices and smart trainers, activity archive, achievement tracking, yoga, mental training, strength training, and instant sharing to Strava, TrainingPeaks, Garmin Connect, Final Surge, and Today's Plan, it’s the only training app you need.


    FTP isn't enough. Train like the pros with 4DP™

    Training apps that just use a simple Functional Threshold Power (FTP) test to set power targets don't know what you're truly capable of. That means workouts that aren't as effective as they should be. The Sufferfest created Four-Dimensional Power™  to reveal your complete power profile and ensure that every power target in every workout is tailored to your unique physiology. You’ll work at the exact intensity necessary to get stronger, faster, and more powerful, without wasting a single pedal stroke.



    All of your activities are recorded in your Passport, allowing you to analyse your performance and keep track of your progress. Instantly upload your activities to Strava, Garmin Connect, TrainingPeaks, Today's Plan and Final Surge to inspire the world with your Suffering.


    Yoga, Mental Toughness, and Strength Training for Cyclists

    You're going to need all of the physical and mental strength you can muster to make it through 10+ hours on the bike in grueling conditions. We have your back.

    Thirty-six Yoga for Cyclists videos will help improve your strength, enhance your flexibility, and speed recovery. You'll also be able to build your mental toughness with a 10-week Mental Training Program of 20 audio modules and associated exercises. Once you finish the event and are sufficiently recovered, check out our Strength Training for Cyclists program. We'll help you build functional strength that directly improves your performance on the bike.
