Zwift Racing League 2025/26 Round 4 Details: Routes, Rules, Registration + More

Now in its 19th round, Zwift Racing League continues to take racing to the next level on Zwift! Registration is now open for the fourth round of the 2025/26 season, which begins on April 7.

This page contains everything you need to know about the current ZRL round, and is updated as WTRL announces new details.

Intro to ZRL

Zwift Racing League (ZRL) is team-based racing for all abilities. It’s also the world’s largest virtual cycling competition, with over 30,000 riders of all abilities participating in each of the past two seasons!

Organized by WTRL, this is a team-based points competition spanning multiple weeks, with teams divided into divisions based on time zones and ability. Races take place every Tuesday, and the season is divided into distinct rounds with brief breaks in between.

ZRL is Zwift racing at its highest level. Its unique structure and varied race formats drive serious Zwift racers to show up week after week while providing a place for new racers who jump in and find their first team home.

Key Changes this Round

Zwift + WTRL continously collaborate to modify ZRL’s structure and rules with the aim of engaging as many racers as possible. Heading into this final round of 2025/26, no rules have changed according to WTRL. But it is worth noting that this final round has only 4 races!

For details on ZRL rules, see the ZRL Rules page >

Routes and Dates

Each ZRL round comprises weekly races which are either scratch races, points races, or team time trials (TTT). Scratch Races and Points Races are both actually points-based in terms of final results, but Points races include intermediate segments while Scratch Race points are all earned at the finish line. TTT winners are the teams who complete the race course fastest, with team time taken from the fourth rider across the line.

Race #1: Hell of the North
April 7, 2026 (TTT)

The round begins with a team time trial on a route we’ve never TTT’d before. Despite starting on Les Intestins, Hell of the North is quite flat… until the final 2.7km climb up the Petit KOM! New this round, WTRL says we’ll get a Draft Boost powerup in the pens and at all arches, for a total of 5 Draft Boosts.

• 1 Lap of France’s Hell of the North (20.1km, 241m elevation)
• PowerUps: Draft Boost in start pen, and at all arches 🛈

Race #2: The Classic
April 14, 2026 (Points Race)

The first points race of Round 4 finds us racing CCW loops of Jarvis Island, which is basically uphill for the first half, and downhill for the second! Points will be contested on the KOM and sprint segment each lap, with a flat finish.

• A/B: 6 Laps of Watopia’s The Classic (32.3km, 310m elevation)
• C/D: 4 Laps of Watopia’s The Classic (22.9km, 212m elevation)
• Intermediate Segments (FAL+FTS):
  • Jarvis KOM
  • Jarvis Sprint
• PowerUps 🛈 TBD

Race #3: Croissant
April 21, 2026 (Scratch Race)

The only scratch race of round 4 is on a flat French circuit with a slightly uphill long sprint finish. Who will sit in the pack and trust their sprint, and who will try to go long?

• A/B: 4 Laps of France’s Croissant (40.4km, 219m elevation)
• C/D: 3 Laps of France’s Croissant (31.1km, 170m elevation)
• PowerUps 🛈 TBD

Race #4: Double Span Spin
April 28, 2026 (Points Race)

The final race of the round takes us onto repeated CCW loops of New York’s Manhattan and Brooklyn bridges, where both the sprint and KOM sections are draftable uphill efforts.

• A/B: 5 Laps of New York’s Double Span Spin (40.6km, 531m elevation)
• C/D: 3 Laps of New York’s Double Span Spin (26.6km, 371m elevation)
• PowerUps 🛈 TBD

Race Timeslots

Some divisions and start times are adjusted between rounds. Use the table below to find a time slot that works for your team. Please note that time slots may shift a bit – we will update the table below once WTRL publishes it for round 4.

Teams/Registration

Team registration is already open (go to wtrl.racing/zwift-racing-league/participants/ and click “Register a Team”). Registration closes April 4, 2026 at 05:00 UTC.

ZRL is a team-based competition – you cannot sign up as an individual rider. Teams can roster up to 12 racers, but only 6 can race in each event. Teams must have at least 4 riders on their roster, and a rider can join as many teams as they’d like, but only a maximum of two teams per league category.

Want to race, but don’t have a team? Here are seven ways to find a team:

1. Recruit friends onto a new ZRL team, then sign up your team at wtrl.racing/zwift-racing-league/participants/.
2. If you’re already a member of a larger Zwift Club, contact a senior Club representative to see if you can join one of your Club’s ZRL teams.
3. Join an official team-lead ZRL Group Recon Ride (see below) where several teams can be found looking for more riders. These run several times a day, starting two weeks before the first race.
4. Join the ZRL Facebook Group and post preferred race times/league, Pace Group Category, and any other preferences under the #zrlteamhunt tag where many teams are eagerly waiting.
5. Reply to one of the #zrlrecruiting posts that teams make in the ZRL Facebook Group if you don’t want to post your own request.
6. Reach out directly to WTRL and they can match you to a team based on race times, category, and team preferences.
7. Use the new “WTRL Team Finder” tool once it becomes available at wtrl.racing/zwift-racing-league/teamhunt/.

First-Timer Tips

If this is your first time racing on Zwift, here are a few tips to get you started fast:

1. You must create a WTRL profile linked to your Zwift account – do so at wtrl.racing/registration
2. The minimum category you’ll race is determined by your power history on Zwift. See this post for details.
3. Riders must use a power sensor to transmit power to the game – this would be a smart trainer, smartbike, or power meter. (You’re allowed to race C and D categories with a “classic” trainer and virtual power, but your points are cut in half.)
4. Heart rate monitors are required. (You’re allowed to race without a HRM, but your points are cut in half.)
5. Cadence monitors are required.
6. You’ll want to have at least a few races under your belt before you try to join a team, so you are confident that you’re in the correct category. It causes a lot of hassle if you join a team and are forced to upgrade to a new category mid-round!

Race Recon Events

If you’re unfamiliar with a particular week’s race course, join a ZRL recon ride! These happen multiple times per day and are led by experienced racers who may share route info and racing tips as you ride.
