Last week, Zwift launched two summer mini challenges named “Cardio Crusher” and “Heat Check”. Each consists of 5 workouts, and completing them earns you an XP bonus.
Cardio Crusher Workouts
“Get ready to sweat! Cardio Crusher is your ticket to staying fit, fast, and fired up all season. With five targeted workouts built to boost endurance, power, and speed, this challenge keeps your summer training locked in—so you show up stronger for every ride, indoors or out.”
Heat Check Workouts
“Summer’s here—are you ready to bring the heat? Heat Check is all about staying sharp, fast, and race-ready, even when outdoor riding is in full swing. With structured workouts designed to maximize your time and build power, this challenge proves that the smartest riders don’t just ride more—they ride better.”
Joining a Challenge
To sign up for one of these Challenges, just click its card on the home screen under “Challenges”, pick a workout, and go!
Mini challenges are typically available for 3 months. These two challenges both expire on August 12.
Challenge Rewards
Your reward for completing all five workouts in one of these challenges? Boosted fitness, of course. B
But you’ll also earn a total of 2000XP as you progress through the 5 workouts.
Tip: do one of these workouts each week on the Route of the Week to earn a 500XP bonus!
