What is Zwift?
Zwift is the indoor cycling and running platform that turned smart trainers from boring basement equipment into a gateway to virtual worlds. Founded in 2014 by Eric Min and Jon Mayfield, Zwift connects to your smart trainer or treadmill and places you in a 3D virtual environment where you ride and run alongside other athletes in real time. Every workout syncs automatically to Strava.
It is the biggest thing in the category by some distance, big enough that in April 2026 it bought its closest rival, ROUVY.
Key Features
Virtual Worlds
Ride through Watopia (Zwift's flagship fictional island), London, New York, Paris, and other rotating worlds. Each course features varied terrain including flat roads, rolling hills, and serious mountain climbs that adjust your trainer's resistance in real time.
Structured Workouts & Training Plans
Access hundreds of structured workouts designed by professional coaches, organized into multi-week training plans for everything from base building to race preparation. The ERG mode locks your trainer to specific power targets so you can focus on pedaling.
Group Rides & Racing
Join organized group rides led by community leaders or compete in races through Zwift Racing. Events run around the clock, so whatever time you can actually get on the trainer, something is starting.
Strava Integration
Every Zwift activity automatically uploads to Strava with full power, heart rate, and cadence data. Your virtual kilometers count toward Strava challenges, and your friends can see your indoor efforts on their feed.
Who It's For
- Fair-weather cyclists who need motivation to train indoors
- Time-crunched athletes who want efficient structured workouts
- Competitive riders looking for year-round racing
- Runners who want treadmill workouts with a social element
- Triathletes fitting in bike sessions around swim and run training
How It Compares
Zwift is the largest platform in the indoor training space, with the most active user base for group rides and racing. Where platforms like ROUVY focus on augmented reality with real-world video routes, and TrainerRoad emphasizes pure structured training without the virtual world, Zwift balances both social interaction and training structure. The trade-off is its subscription price and the requirement for a capable smart trainer.
Worth knowing: Zwift acquired ROUVY in April 2026. Both apps continue to run independently with separate subscriptions and roadmaps, and Zwift Ready trainers and the Zwift Ride frame now work with ROUVY too. See our full Zwift vs ROUVY comparison.
What equipment do I need for Zwift?
At minimum, you need a smart trainer (which controls resistance automatically) or a classic trainer with a speed/cadence sensor. You also need a device to run the app: a computer, iPad, iPhone, Apple TV, or Android tablet. A heart rate monitor is recommended but optional.
Does Zwift work with any smart trainer?
Zwift supports most ANT+ and Bluetooth-enabled smart trainers from brands like Wahoo, Tacx (Garmin), Saris, and Elite. It also works with smart bikes like the Wahoo KICKR Bike and Tacx NEO Bike.
Do Zwift rides sync to Strava automatically?
Yes. Once you connect your Strava account in Zwift's settings, every completed activity uploads automatically. It includes full power, heart rate, cadence, and distance data.
What does Zwift cost, and is there a free trial?
$19.99 a month or $199.99 a year in the US. Zwift bills in local currency elsewhere: £17.99 / £179.99 in the UK, €19.99 / €199.99 in the EU. The monthly plan comes with a 14-day free trial. The annual plan doesn't get a trial, but a first-time subscriber who cancels within 30 days gets a refund.
