Zwift is the Official Training Software Provider of the Tour de France, and they’re going big with a series of Tour Fever events in July.
Zwifters can join to conquer virtual versions of the same mountains the pros race, take on a virtual L’Étape du Tour fondo, unlock the brand new Didi the Devil and Tour Fever kits, and more. See details below!
Climb Portal Challenge

Four different climbs will be featured on the same day they feature in the Tour, with events held across three days:
Climb (click for details) | TdF Stage | Dates |
Mûr de Bretagne (1.96km, 129m) | 7 | July 10-12 |
Col de la Croix Saint-Robert (5.7km, 346m) | 10 | July 13-15 |
Hautacam (12.7km, 1029m) | 12 | July 16-18 |
Col de la Madeleine (14.3km, 1118m) | 18 | July 23-25 |
Ride all four climbs (solo or in an event) to complete the challenge. You will receive rewards as you progress through the challenge:
- Complete 1/4 climbs = Tour Fever Kit (see images below)
- Complete 2/4 climbs = 1000XP Bonus
- Complete 3/4 climbs = Didi Kit (see images below)
- Complete 4/4 climbs = Didi Cap (see images below)
Accessing the climbs and events is easy. It’s hard to miss the Climb Portal Challenge Zwift has just rolled out for the TdF! Click the homepage banner, register for the challenge, then you have access to all of the climbs above whenever you’d like.

The Climb Portal events are technically group rides, not races. But you can still chase leaderboard placings and try to set your fastest time on each climb! Be sure to use a lightweight bike and wheels. Here’s a guide that tells you the lightest bike frame and wheelsets available at each Zwift level.


A fully-upgraded Specialized S-Works Aethos paired with Zipp 353 NSW wheels is the fastest climbing bike in game. If you’re looking at non upgraded bikes, the Specialized S-Works Tarmc SL8 with Zipp 353 NSW wheels it the best climber.
